Dual boot Windows 7 and Arch from 2 seperate drives (UEFI)

Hello everyone, I've been working on installing Arch to a secondary hard drive for the past few hours, but I am trying to make sure I won't mess up my Windows 7 install. I have found several topics talking about dual booting Windows 7 and Arch, but not a whole lot on booting them from separate drives. My drives are currently setup as follows.
sda (120GB SSD for Windows 7)
sda1 (100MB System Reserved NTFS partition)
sda2 (Windows 7 install)
sdb (1TB HDD for Windows programs, files, etc)
sdb1 (1TB NTFS partition)
sdc (1TB HDD)
sdc1 (boot 512MB FAT32)
sdc2 (root 500MB ext4)
sdc3 (home 300GB ext4)
sdc4 (swap 10GB)
rest unallocated "free space"
I used Gparted to create the partitions. I ended up getting hung up on the "Create Filesystems" sections, specifically this line"
# mkfs.fat -F32 /dev/sdXY
Now that I am looking at it, I'm thinking the "Create Filesystems" section maybe isn't necessary because I've used Gparted?
If it isn't necessary, when I get to the "mount the EFI System Partition to /boot" section, would I simply use
# mount /dev/sdc1 /mnt/boot
instead of
# mount /dev/sdXY /mnt/boot ?
The way I had this setup with Ubuntu was 3 partitions on sdc (/, home, swap) and I set my PC to boot to the sdc drive on startup. The boot loader would then give me the option to boot into Ubuntu or Windows 7, and I never had to alter the sda or sdb drives at all. Is this possible through Arch? My thinking is that even if it isn't, I should still be able to enter the BIOS boot menu and select which drive to boot manually correct? That wouldn't be too big of a deal for me because I spend 90% of my time in Linux, and only use Windows for Photoshop and gaming occasionally.
Thanks for taking the time to read this. I would have just tested this out, but I am afraid of messing up my Windows install.

After several sleepless hours I had to give up and go to bed about 5 hours ago. The installation process went smoothly (or so I thought). I followed the tutorial closely and upon rebooting I was met with a blinking cursor. After some googling I found others who said I should press TAB, but nothing seemed to work.
I rebooted to the iso disk and found the "boot installed OS" option and noticed it said "Press TAB to edit". I then found the boot parameters and tried everything from hd0 0 to hd4 4. I believe I have Grub setup correctly because every option besides hd0 0 either says "Booting..." and then gets stuck, or says "That disk and partition combination does not exist". So yea, I think hd0 0 is the correct boot path, it just gets stuck with the blinking cursor.

You have the right idea. You want to install a bootloader on sdc1 which will be able to boot both Arch and Windows.
Your best bet would be to use something like rEFInd. It has a "scanfor" option that should automatically detect your BIOS-configured Windows installation and add a boot option for it. Note that depending on your motherboard, you may have to switch to UEFI-only mode and Windows will be unbootable without the assistance of a UEFI program which is backwards compatible with BIOS (like rEFInd).
Thank you for the link. Considering I can't get into my install and the actual install only took about 30 minutes, I think I am going to just start from the beginning again with REFIndr. It seems much simpler. I only used Grub because I've used it before with Ubuntu, but my very limited knowledge is telling me Grub is probably the problem.
MoonSwan wrote:Just an idea: My bios has a "Boot-up Prompt" which I can invoke when it's POSTing by hitting F11. This brings me to a menu that allows me to choose which drive I want to boot up that day. I use it when Syslinux isn't working properly (Which is right now as a matter of fact ...) in order to boot Windows so I can do some SCII, for example. I, too, dual-boot but I have both OSes on different SSDs. So my 120GB Crucial SSD has Arch on it and the 240GB Kingston has Windows, SCII, Portable Apps, etc and nary the two shall meet. It makes dual-booting easier in the case of a corrupt OS or MBR or what-have-you. You may want to give your Bios a better look to see if you can do the F11 trick. It probably can and will usually tell you so at POST by printing that information on-screen along with your drives-detected and other messages (I hit Pause sometimes to read all the POST messages).
This is exactly what I was talking about doing when I mentioned:
My thinking is that even if it isn't, I should still be able to enter the BIOS boot menu and select which drive to boot manually correct?
That's good to know, because even if this next install doesn't work I think if I pull the other drives I should be able to get it working fairly easily.
Thanks again everyone.

Dual Booting Windows and Arch (SOLVED!)

Hello all, I'm having trouble getting a windows partition activated again. (Windows was on here for many years, then I installed arch on a separate partition.)
Here is the layout of fdisk -l:
Disk /dev/sda: 100.0 GB, 100030242816 bytes
255 heads, 63 sectors/track, 12161 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x00000000
Device Boot Start End Blocks Id System
/dev/sda1 * 1 7833 62918541 7 HPFS/NTFS
/dev/sda2 7834 12039 33784695 83 Linux
/dev/sda3 12040 12161 979965 82 Linux swap / Solaris
sda1 is the windows partition, and sda2 is the arch partition. The linux partition SHOULD be primary bootable (have the * next to it),but all my attempts to do this have failed. (I've used "testdisk" to change the flags, but for some reason it keeps reverting back to setting sda 1 as primary bootable after a reboot or 2).
This is the pertinent section of /boot/grub/menu.lst:
title Arch Linux
root (hd0,1)
kernel /boot/vmlinuz26 root=/dev/disk/by-uuid/f3be3baa-3b62-460c-8801-64b0b1cca$
initrd /boot/kernel26.img
# (1) Arch Linux
title Arch Linux Fallback
root (hd0,1)
kernel /boot/vmlinuz26 root=/dev/disk/by-uuid/f3be3baa-3b62-460c-8801-64b0b1cca$
initrd /boot/kernel26-fallback.img
# (1) Windows
title Windows XP
rootnoverify (hd0,0)
makeactive
chainloader +1
I have a . . . modified . . . copy of XP Professional, which comes with a recovery console to reinstall the MBR if it's necessary.
From what I've researched, I somehow need to reinstall grub to the second partition, make the second partition primary bootable, then rewrite the MBR on the first partition, and correct any command errors in menu.lst, but I haven't really figure out a way to do it.
Thanks in advance for your help!

I read up on some documentation of installing GRUB to the MBR.
So far, I went into ArchLive (from the cd) and did the following
grub> root (hd0,1)
grub> setup (hd0)
The installation reports success with no errors, but the problem persists. Arch linux will boot fine, but when I select XP it flashes my configuration, like so:
title Windows XP
rootnoverify (hd0,0)
makeactive
chainloader +1
then kicks me back to the OS select GRUB screen. Did I install it to the wrong place?
EDIT:
I decided to issue this command:
grub> setup(hd0,1)
It reported some errors, then arch couldn't mount the ntfs partition because of possible MFT cluster errors.
Using testdisk, I repaired the boot sector and MFT clusters, then using ArchLive reinstalled grub with grub>(hd0)
Arch and Arch Fallback will boot correctly, but now the windows side shows an error:
rootnoverify (hd0,0)
makeactive
chainloader +1
Loading stage2Read Error (or something to this extent)
I wonder if this error brings me closer or farther to a solution?
Thanks for the replies so far!

Dual Boot Vista and Arch

Hey, I am attempting to set up my laptop to dual boot Windows Vista and Arch Linux.
The problem I'm having is after installing Arch my laptop still boots windows w/o going to the grub
I started with having Windows Vista installed on the laptop, and then shrank down the partition with vista by 30 gigs for Arch.
I was following the Arch setup guide in the wiki along with the Dual Boot Windows and Arch guide in the wiki [wiki]Windows_and_Arch_Dual_Boot[/wiki].
My partitioning Scheme is:
/dev/sda1 1.46 gb (some sort of toshiba recovery partition I believe)
/dev/sda2 117.8 gb (Vista Partition)
/dev/sda3 1 gb (Swap partition)
/dev/sda4 29 gb /root partition
According to the Dual Boot wiki article, I should install the grub to /boot, which in my case is in /root which I did.
The thing that confuses me about this is if I install the grub to /boot how do I get the grub to boot before the windows MBR?
Thanks in advanced

It still works fine. It doesn't matter if its not in root directory. Others linux OSes have their bootloaders in the same directory and it manages to boot just fine.

Dual Booting Windows and Solaris

Hi
how do i dual boot windows and solaris
Do i install windows first and then solaris or do it the other way around..?
how do i make sure that Windows and Solaris appear in my boot options..?
Is their a guide on doing this...?
Thanks
Liam

Hey I did a quick google search for you. So I havent tried this method myself but it sounds reasonable.
The text below is from the following link:
http://www.hccfl.edu/pollock/AUnix1/DualBoot.htm
"Solaris boot loader
Partition the drive to leave at least 2GB of space available for Solaris;
more drive space is desirable.
As with Linux, install Windows first then Solaris.
Do not use the Installation CD but boot and install
from Software CD 1.
If you accept the default partitioning scheme which
the installer provides you will soon run out of space in
your / and /usr partitions since only enough space is
allocated to install the system.
All extra space is allocated to /export/home.
A typical installation on a 4.5GB partition might look
something like this:
Filesystem Size Used Avail Use% Mounted on
/dev/dsk/c0d0s0 900M 536M 310M 64% /
/dev/dsk/c0d0s1 334M 109M 192M 36% /var
swap 671M 8.0k 671M 1% /var/run
swap 671M 8.0k 671M 1% /tmp
/dev/dsk/c0d0s5 845M 222M 565M 29% /opt
# (FAT32 partition):
/dev/dsk/c0d0p0:1 5.0G 3.3G 1.6G 66% /c
/dev/dsk/c0d0s7 1.1G 92M 954M 9% /export/home
/dev/dsk/c0d0s4 752M 225M 474M 33% /usr/local
The Solaris boot selector enables you to choose either
Solaris or Windows with Solaris as the default.
(I prefer grub or lilo!)
To mount FAT under Solaris:
# mount -F pcfs /dev/dsk/c0d0p0:c /dos (or �:1�?)
And the vfstab file:
/dev/dsk/c0d0p0:c - /dos pcfs - yes -
To create a GRUB boot floppy, follow these steps:
$ mkfs -t ext2 /dev/fd0
$ mount /dev/fd0 /mnt/fd0
$ mkdir /mnt/fd0/boot /mnt/fd0/boot/grub
$ cp /boot/grub/stage[12] /boot/grub/grub.conf \
> /mnt/fd0/boot/grub
$ /sbin/grub --batch <
Hope this helps!

[SOLVED] Dual Boot Window 7 & Arch on a Uefi system.

From the Wiki
Windows 7 x86_64 versions support booting in x86_64 UEFI mode from GPT disk only, OR in BIOS mode from MBR/msdos disk only. They do not support IA32 (x86 32-bit) UEFI boot from GPT/MBR disk, x86_64 UEFI boot from MBR/msdos disk, or BIOS boot from GPT disk.
I don't understand this. As stated in the title I have a ueif system so that means I have to create a GPT disk ? I already have a gpt disk which I confirmed by running Arch Live USB. Under type it said GPT. I don't understand this at all
However if Arch is installed in BIOS-GPT in one disk and Windows is installed in BIOS-MBR mode in another disk, then the BIOS bootloader used by Arch CAN boot the Windows in the other disk, if the bootloader itself has the ability to chainload from another disk.
Note: If Arch and Windows are dual-booting from same disk, then Arch SHOULD follow the same firmware boot mode and partitioning combination used by the installed Windows in the disk.
In the Note above it says both Arch and Windows follow the same boot mode if they are dual booting from same disk. I DO NOT want to do this. I have already decided to partition my drive with 200 Gb going to Windows and 500 Gb going to Arch. Does this mean that I should install both in different modes i.e. Arch in Bios-GPT and Windows in Bios-MBR.
The recommended way to setup a Linux/Windows dual booting system is to first install Windows, only using part of the disk for its partitions. When you have finished the Windows setup, boot into the Linux install environment where you can create additional partitions for Linux while leaving the existing Windows partitions untouched.
UEFI systems
Both Gummiboot and rEFInd autodetect Windows Boot Manager \EFI\Microsoft\Boot\bootmgfw.efi and show it in their boot menu, so there is no manual config required.
For GRUB(2) follow GRUB#Windows_Installed_in_UEFI-GPT_Mode_menu_entry.
Syslinux (as of version 6.02 and 6.03-pre9) and ELILO do not support chainloading other EFI applications, so they cannot be used to chainload \EFI\Microsoft\Boot\bootmgfw.efi .
Computers that come with newer versions of Windows often have secure boot enabled. You will need to take extra steps to either disable secure boot or to make your installation media compatible with secure boot.
Being a beginner should I go with Gummiboot then. GRUB made a mess last time.
Also my secure boot is NOT enabled so is that good.
I have read the FAQs, Beginner's guide, Installation Guide, Dual Boot wiki entry but I just don't understand the above concepts. But it looks this this is the main thing in dual booting. Almost everything else is doable but this I have to get right on account of what happened the last time I installed Arch without getting the above right.

A few issues with the dual boot setup
Hello again, I lost my dual factor authentication grid from lastpass. Opensuse was acutally overwriting new pdf files over my old pdf files so now that grid pdf is actually an Arch cheat cheet with the name last_pass_grid.pdf. And the gmail account I used to register to Arch forums is also in last pass.
This is why I created another account. I am some arch lovin.
The installation went smoothly but I could not dual boot Windows7 with Arch because my Win7 image is not UEFI bootable so had to dual boot win8(not a fan at all) and arch.
Almost everything is working correctly. I have a few issues that aren't affecting how the system is working but they still need sorting out.
I'll do them one at a time but I want to know from the admins if I should start a new thread? Because in a way this thread accomplished it job i.e. win7 and arch dual booting in uefi system.
If the answer is yes I should create a new thread depending upon the issue then I will do that but in case its a no since I have only 2-3 problems I am going to ask help for the first one.
My gummiboot is not working on startup. I have to press f12 and use bios booting menu to boot. The problem with that is if I put Windows at the top of the boot priority the bios does not show F12 and F2 at the time of booting up so I can't access the boot menu. I have to boot into Windows and crash it by holding the power button and then the F12 options shows up and I am able to boot into Arch. If I put Arch at the top then Windows keeps restoring back to an earlier version due to start up options.
NOTE : I can't be sure but one it did work(only once). I checked the images online to compare with what I saw and its very similar. An all black screen with three bootloading options
Windows
Arch
Opensuse(don't know why I created a completely new GPT partition table)
This is what I did while installing Gummiboot
# mount -t efivarfs efivarfs /sys/firmware/efi/efivars
# pacman -S gummiboot
# gummiboot install
I tried going through the gummiboot to see if I can do something but it very difficult to comprehend as a beginner. All I get is the characters gummiboot understands but thats all.

Dual boot Windows and Linux?

I recently bought a T61, and will be taking a programming course. One prof I spoke with said they ask us to use Unix tools, so one option is to dual boot linux and Windows. I haven't decided yet whether I will keep Windows Ultimate, or go to XP for this. But I was wondering how easy/hard is it to make this work, and what kind of steps need to be taken? If you could point me towards any good tutorials/guides that would be appreciated too.
Also, I have never really used linux, so which version is best? I will be needing it for programming, but also still want to do the basics like web surfing, music, dvd's, burning discs, etc. I have an old copy of Ubuntu that I never used, but its probably about 4 years old. Is this still acceptable or will I need something newer?

Hi,
If it's just a couple of programming courses that you are going to take I suggest you'd try out VMware player:
http://www.vmware.com/products/player/
You can get this software for free and since your system packs a lot of punch it will be able to run it smoothly without any hassle. I'm an engineering grad student and I have to do alot of programming. I've used VMware player before to do some software developement in Ubuntu when I didn't have enough HD to install dual boot but still couldn't do all my other stuff without XP.
VMware Ubuntu will need a bit of fiddling to get it work just right (USB devices, etc) but it shouldn't be harder than installing a dual boot (actually it is alot easier for my opinion). The only down side is that file sharing between VMware and Windows can be somewhat difficult. I used an external USB drive to share my files but you could always set up Samba to handle file sharing.
I hope this helps out with your decision.

Boot Windows AND FreeBSD from my MacBook Pro 8,3 using an external DVD drive. I'm considering to remove my DVD-ROM and replace it with an SSD drive. That doesn't seem to work. Why not?

As the title says, I'm attempting to boot off my favorite operating systems, Mac OS X, Windows 7 and FreeBSD from an external DVD drive. However, for some odd reasons, booting the Windows DVD and FreeBSD 9.1 install DVD from the external drive does not seem to work. I was able to create a bootable USB with the Windows installer, but whenever I attempt to do the same with FreeBSD, I only get an error message that says "No bootable device -- press any key to restart." Is this a limitation that Apple deliborately created? If so, why won't Apple let its customers do whatever they please with their computers, considering that customers who want to change the hardware and/or operating systems knows what he is doing, without having to worry about some silly Apple limitations?
If I sound rude, I apologize for that, as no impoliteness is intended from my side.
In advance, thanks. Have a wonderful day, everyone.

That is only partially correct at best.
When you are booting off Windows or any other operating systems that usually don't support EFI (including Windows), your Mac uses something called CSM-BIOS. And as long as that CSM-BIOS implementation on EFI-based Mac do not support booting off from USB (note that Mac OS X Installer works fine when booting from USB), not even a USB Apple SuperDrive which once was an internal drive, there mot definately is something for Apple to fix.
When attempting to install Windows via BootCamp, a somewhat hybrid GTP/MBR table is created. When you boot off the installer disc of the OS you intend to install (i.e. Windows 7, FreeBSD, etc), your Mac might not support the EFI boot option (at least my 2011 17-inch MacBook Pro doesn't support that), so the only way of booting that second OS installer is via the regular BIOS, which Apple's EFI based systems implement as CSM-BIOS.

Dual booting Windows 7 & Arch...

I have 2 SATA hard drives on my system...
320gb & 500gb
I have 6 gigs ram, triple core 2.1ghz w/256mb HD 2400 ATI pciE
Im reading the wiki page https://wiki.archlinux.org/index.php/Wi … _Dual_Boot
and I have some questions and am seeking some advice..
I was thinking about putting (in the bios) the 320 as primary w/ windows 7
and using the 500 for linux.. 300 ( /boot=100mb, /=20gigs /swap=2gigs /home= approx 275gigs) and 200gb FAT32 to share music,pics,documents, et al with both OS's
maybe using a gparted cd to make the 320 ntfs, /boot ext2, /root & /home ext4 /swap as swap and 200gigs as fat32
then installing windows on the 320, then using the arch ftp install to install arch on sdb (second sata drive) using the partitions I've explained about.
now for Grub.. where I get lost is.. i read on one of the many forum posts i read, if you install 7 first, then arch, everythign will work fine and when you reboot you'll have a choice.. now this answer/comment goes against the wiki that says you have to set up grub to do the dual boot.. or am i wrong, will it just "work" (it does with other distros, but I know arch doesnt hold hands like the others, and I really dont want to leave arch jsut to dualboot for the few windows needs i have , photoshop, a good printer, office 2010, and afew other windows programs i still enjoy using for work and play)
does anyone have any "easier" to follow directions then the wiki to dualboot win 7 and arch? I'm reading and re-reading and re-reading the wiki again, and it seems like greek to me..
anyone have any other suggestions.. i have win7 in a virtualbox machine, but the usb hub isnt working.. (started happening since 4.x.x.x came out) thought 4.0.0.2 would "fix" this issue, so i made a new vm of win7 and same usb hub isssues in device manager.. so it MUST be a virtual box issue.. and from what I've read, its not being "fixed" anytime soon.. and I cant use my printer on arch no matter what I've done..
so any advice would be appreciated.. don't want to start something I cant finish.. ( i can install arch with my eyes closed i've been through enougth trial and screwups)
thanks in advance

Heres how I do it:
1. Split my drive into one primary partition and an extended partition with logical partitions for Linux.
2. Install Windows 7 (first) to the primary partition and Arch Linux inside the extended partition.
3. Install grub to the drive and just uncomment the lines for Windows. Remember to leave "makeactive" commented out.
4. Thats it.

[SOLVE] Dual Boot Windows and ArchLinux with Syslinux

Ok, i installed ArchLinux on my laptop with Windows XP (syslinux) and I cannot find get Windows to boot or mount it. I have tried to do what i can to do this but cannot. I Installed XP first like a should and something i think might be needed to know is after i created the partitions scheme (10Gb (boot partition), 50GB (XP), 80GB(was unallocated)). The installation disk formated both 2 partitions in NTFS but i installed XP on the second and Windows reported them as C and D drives. Windows being D. Thought that was bit werid thinking Windows installed the mbr on that partition. When I installed ArchLinux, it did have the boot flag set on 10GB (or C drive).
Since I installed ArchLinux, I have been unable to find a solution to mounting/booting to Windows. Installed NTFS-3G and that didn't work when i tried mount /dev/sda3 windows and i did created a folder named windows but got ...
mount: wrong fs type, bad option, bad superblock on /dev/sda3,
missing codepage or helper program, or other error

Here is the partition table:
/dev/sda1 one HUGE linux /boot primary partition (assuming ext4)
/dev/sda2 "name" of the extended partition
/dev/sda3 primary Windows partition (assuming NTFS)
/dev/sda5 logical Linux root partition (assuming ext4)
/dev/sda1 to /dev/sda4 are either all primary, or three primary and one extended. After /dev/sda4 all partitions are logical. If you're still wondering why is there no /dev/sda4, it's because you have 2 primary and one extended, so /dev/sda4 is reserved for another primary partition.
Windows problem:
The /dev/sda1 which Windows named C: is Windows equivalent of linux /boot. When you told linux to place its /boot on /dev/sda1 it formated boot files of Windows. Now you have Windows OS with no kernel. In other words there is no way to boot Windows if you don't reinstall it. Actually there is a way, but you would than screw up Arch.
Mounting problem:
You can never mount extended partition, only logical (an extended partition is made of logical partitions). You want to do:
sudo mount /dev/sda3 -t NTFS-3g -o rw,uid=YourUserName /path/where/you/want/this/partition/mounted
EDIT:
Try it this way:
- Backup all your data
- Delete every partition
- Start Windows installation
- Make only one partition (c:/ for Windows)
- Let Windows make another partition
- Make one more so you could have a data partition, which does not need to be formated to reinstall Windows
- Start Arch installation
- Get to partitioning
=Partitioning=
- /dev/sda4 extended (take the rest of the drive)
- /dev/sda5 logical /boot 512MiB
- /dev/sda6 logical / 20GiB
- /dev/sda7 logical /home (the rest)
Making a separate /home partition will come in handy when reinstalling Arch (any linux distribution), or switching between distros, because it is the equivalent of D:/ in Windows. Also consider LVM.

Dual-Booting Windows and Android on Yoga Tablet 2 13?

So I am a big fan of the lenovo yoga tablet so I started looking into the new versions of the tablet and I came upon something curious. both the yoga tablet 2 pro and the yoga tablet 2 13 (windows) have the same processor (a 64-bit processor) as well as very similar technical specs(the main difference being the windows edition has 4GB of ram instead of 2GB and a larger battery no doubt due to the removal of the integrted pico projector). as well Lenovo has the source code for the android build in the pro available on the website.
So my question is if both are running off the same 64-bit processor is there anything stopping someone from compiling the yoga 2 pro source code and installing the yoga 2 pro android OS onto the Windows version of the tablet (dual-booting both) aside from secure boot needing to be disabled?
after scouring the internet and asking a few lenovo representatives I have found absolutely no information on this (the lenovo reps I spoke to couldn't even confirm the specs of the processors but I found that data from the intel ark database) and it is something I really would like to do if possible (especially with android 5.0 having x86 support integrated in the vanila build)
So anyone have any information on anyone trying this or something similar being attempted?

so, lenovo putted a really bad bios on thoses tablets.
http://forums.lenovo.com/t5/Windows-based-Tablets/Alternatives-OSes-and-CMS-under-Yoga-1051/td-p/190...
To make it short, the uefi bios used on yoga tablets support only x86 so, the x86-64 instruction set can't be used, on windows. Without CSM (compatibility support module) you can't even try to boot some oses. For linux you need to mod it, i'll try later but, i can't build a new bios and lenovo is not present on this board

Stream 7, dual boot, windows and android

Given that the HP Stream 7 can be equipped with lots of storage, why not dual boot it with Window and Andoid so I can have the best of both worlds
can this tablet be configured to do that?

Before going to a lot of trouble, I'd get a boot disk on USB with Android X86 on it. Then boot off the USB.
I'd also suggest using 4.22 or 4.4, not 5.0. "Everyone" is still working on 5.0.x.
I've not had much luck on a few devices and Android x86 - hence my suggestion. I have NOT tried it on the Stream 7

Dual boot gentoo and arch

Can someone help me with a grub entry I'll need for my Gentoo grub.conf to boot Arch?
I want to skip the arch bootloader section on install, so I won't know what kernel is and stuff they use. (well, I guess I could mount the arch partition from gentoo to find out ).
I'll be using the latest cdrom I guess.
Ignore what partitions I'll use. I'm just not familiar how arch boots the kernel.
Thx
My current /boot/grub/grub.conf is:
cat /boot/grub/grub.conf
default 0

Dual boot Windows 7 partition help

I want to dual boot Windows 7 & arch but I need help with figuring out what partitions to make and where to put them because it seems the automatic partition-er won't do the trick for me.
I have two drives that I want to completely format for a fresh, clean install: a 60GB SSD & a 750GB hard drive. I want the end result to be that the SSD only has Windows 7 Pro x64 SP1 installed to it and I will point the 'My Documents', 'My Pictures', etc. to a NTFS partition on the hard disk drive ( I know how to do this folder pointing ). I don't want arch to touch the SSD if possible so I can reformat the SSD separately if I ever just want to reformat Windows. I only want arch to be on the hard disk for that reason. I don't think I care which one handles the OS switching at boot ( should I favor Windows MBR or syslinux? Please give advice. ) And I would assume I make the NTFS partition on the hard disk a primary partition so how do I split up arch for the 3 other primary partitions left since the auto partition from the arch boot CD uses 4?

I'm no expert, but the way I would do it would be like this:
1. Create partitions on the HDD for /, /boot, /home and swap, along with one (or more) for your Windows personal files
2. Set the BIOS to boot from the SSD.
3. Install Windows on the SSD.
4. Right-click the "My Documents" folder, select "properties", then the "Location" tab and choose the new location for the folder.
5. Install Arch on the HDD partitions, and allow the boot manager to install itself in the MBR of the SSD.
Then the whole boot process will be on the SSD... If you ever need to get rid of the Linux bootloader, you can overwrite it with a "clean" Windows one using bootrec.exe (see here: http://support.microsoft.com/kb/927392).

Advice on dual-booting Windows 7 with UEFI motherboard

I'm going to build a desktop PC tomorrow, having finally purchased all the parts for it. I'll be installing Arch as my main OS, and Windows for gaming. However I'm not really versed in UEFI and its uses, advantages/disadvantages; since my laptop just uses BIOS.
My plan is to have 3 drives: 32GB SSD for the / partition, 1TB HDD for /home, and 500GB for Windows 7 x64 Ultimate.
Being unused to UEFI I was thinking about trying to just run everything in BIOS/Legacy mode, but that doesn't seem very sensible to me, especially since I have the hardware so I might as well use it.
So, reading the wiki and forums have led me to conclude that having a 1GB EFI System Partition on the SSD should be sufficient, and use gummiboot for my bootloader.
Other reading about setting up dual boots suggests to me that installing Windows 7 on its own HDD with MBR partitioning and Arch on a separate (set of) drive(s) with GPT partitioning will be sufficient. The reason being that if the BIOS is set up to boot sda, which has GRUB as its bootloader, using GRUB I can choose to boot into Windows despite it being on a separate hard drive.
My questions are (and it occurs to me that I am in the most part just looking to have my ideas confirmed):
1. Have I gotten this all completely wrong?
2. If I'm correct, can the above system of using GRUB on one drive to boot up an OS on another drive be applied to UEFI?
3. Has anybody tried/succeeded/failed to dual-boot in this fashion before me, and if so what did they do?
Thanks one and all! Hopefully I've made myself clear enough here

Using BIOS/CSM/legacy mode can work fine; however, it will probably slow down the boot process by a few seconds, and it will close off some possible future (and even current) advantages, as EFI support in Linux is improved.
So, reading the wiki and forums have led me to conclude that having a 1GB EFI System Partition on the SSD should be sufficient, and use gummiboot for my bootloader.
A 1GB ESP is more than sufficient. In terms of space requirements, 100-500MB is enough, depending on how you use the ESP; but various bugs and default settings make me recommend 550MiB as a good size. Bigger is OK, but wastes some disk space.
A bigger issue is that the ESP won't really benefit much from being on your SSD, since it's read once at boot time. The biggest advantage to putting the ESP on the SSD in your setup is that if you use gummiboot, you'll also have to put the Linux kernel and initrd file on the ESP, so having them on an SSD will speed up the boot process by about 1-5 seconds. Overall, I'd probably put the ESP on one of the spinning disks.
One more comment: gummiboot can launch boot loaders from its own partition but not from other partitions. This can work fine if you plan things carefully, but with three disks and two OSes, you must be absolutely positive that Windows uses the ESP on which gummiboot is installed. I'm not an expert on Windows installation, so I can't offer any specific pointers or caveats on this. If you need something with more flexibility, both rEFInd and GRUB can redirect the boot process to other partitions or physical disks. rEFInd can also redirect from an EFI-mode boot to a BIOS/CSM/legacy-mode boot. (See below.) Overall, rEFInd's flexibility on this score is a plus compared to gummiboot; but gummiboot is covered in the Arch wiki's beginner's guide, which is a plus. You'll have to pick which advantage you prefer. (Note that I'm rEFInd's maintainer, so I'm not unbiased.)
Other reading about setting up dual boots suggests to me that installing Windows 7 on its own HDD with MBR partitioning and Arch on a separate (set of) drive(s) with GPT partitioning will be sufficient. The reason being that if the BIOS is set up to boot sda, which has GRUB as its bootloader, using GRUB I can choose to boot into Windows despite it being on a separate hard drive.
This is an unworkable idea, at least as stated and if you want to do an EFI-mode boot. Windows ties the partition table type to the boot mode: Windows boots from MBR disks only in BIOS mode, and from GPT disks only in EFI mode. Thus, using MBR for the Windows disk will require a BIOS/CSM/legacy-mode installation of Windows. Furthermore, neither gummiboot nor GRUB can redirect from EFI mode to BIOS mode (or vice-versa), so if you do it this way, you'll be forcing yourself to boot Linux in BIOS mode, to switch between BIOS-mode and EFI-mode boots at the firmware level (which isn't always easily controlled), or to use rEFInd to redirect from an EFI-mode boot to a BIOS-mode Windows boot.
Overall, you're best off either using GPT for all your disks and booting all your OSes in EFI mode or using MBR for Windows (and perhaps all your disks) and using BIOS-mode booting for all your OSes.
Under EFI, the boot process is controlled by settings in the NVRAM, which you can adjust with "efibootmgr" in Linux, "bcfg" in an EFI shell, or "bcdedit" in Windows. (The Arch wiki covers the basics at least efibootmgr and bcfg.) In a typical dual-boot setup, you tell the computer to launch your preferred boot manager (EFI-mode GRUB, rEFInd, or gummiboot, most commonly), which then controls the boot process. You set up boot loaders for all your OSes on one or more ESPs. (Note: A boot manager lets you choose which boot loader to run, and a boot loader loads the kernel into memory. GRUB is both a boot manager and a boot loader. rEFInd and gummiboot are both boot managers. The EFI stub loader, ELILO, and the EFI version of SYSLINUX are all boot loaders but not boot managers. Most EFIs include their own boot manager, but it's usually primitive and awkward to use. It's also not standardized, so my computer's built-in boot manager is likely to be different from yours. Thus, I recommend against relying on the built-in boot manager for anything but launching your preferred boot manager.) Thus, the lowest-common-denominator type of setup is to put your preferred boot manager, the Windows boot loader, and a Linux boot loader (which could mean your Linux kernel) on a single ESP. If you want to use multiple ESPs or otherwise split things up, you cannot use gummiboot as the boot manager, since it can't redirect the boot process from one partition to another. (Many EFIs can do this with their own built-in boot managers, but this isn't guaranteed, and it's usually more awkward than using rEFInd or GRUB.)
I know this can be a lot to absorb. The official rules aren't really all that complex, but different EFIs interpret the rules differently, and the different capabilities of the various boot managers and boot loaders creates a lot of subtle implications for how you set everything up.
1. Have I gotten this all completely wrong?
Significant parts of it, I'm afraid; see above. You're working under BIOS assumptions, which don't apply to EFI.
2. If I'm correct, can the above system of using GRUB on one drive to boot up an OS on another drive be applied to UEFI?
GRUB can do this, but gummiboot can't. You set one of those (or something else, like rEFInd) as your primary boot manager. Using both GRUB and gummiboot adds unnecessary complexity, IMHO. OTOH, setting up multiple boot managers or boot loaders is possible, and can give you a fallback in case one fails. For instance, there's a known bug that affects 3.7 and later kernels, mostly on Lenovo computers, that causes the EFI stub loader to fail sometimes. Thus, if you use rEFInd, gummiboot, or the EFI's own boot manager to launch the kernel via the EFI stub loader, having GRUB, ELILO, or SYSLINUX set up as a fallback can provide helpful insurance in case a kernel upgrade causes your normal boot process to fail.
3. Has anybody tried/succeeded/failed to dual-boot in this fashion before me, and if so what did they do?
Many people dual-boot Windows and Linux under EFI. There are a huge number of possible solutions. My own Windows/Linux dual-boot system uses:
rEFInd
rEFInd's EFI filesystem drivers
Linux kernels on Linux-native /boot partitions (two partitions, one for each of the two distributions installed on that computer)
The Windows boot loader on the ESP
This works well for me, but it wouldn't work with gummiboot instead of rEFInd, since gummiboot can't redirect the boot process to another partition. (gummiboot also can't automatically load filesystem drivers.) Arch Linux users who use gummiboot often mount the ESP at /boot, which enables gummiboot to easily launch the Linux kernel. Doing this with multiple Linux distributions would be awkward, though, since you'd end up with two distributions' kernels in the same directory.

Win XP/Win 7 dual boot question and

My replacement motherboard for my crapped out Dell one that was a replacement, crapped out the other week and it was tested with a new power supply to no avail. it was also tested in a shortcut, (connecting the two wires directly, the two that "short out" that turns on the power) and that didnt work either.. (something like that)
My options are:
buy another replacment motherboard and hope it stays working longer than the six months the other did
Buy a new computer and use my old hard drive
thus arising this question:
since the new computer will have Windows 7 on it, can I use that as a slave drive and use my primary drive (not going to loose my data and stuff) I have the primary drive as XP but the new one will use 7, when I put in the win 7 drive as a slave drive, will it boot to 7 or XP and would I have the option to dual boot, even if they are seperate drives..
I think I am writing it a confusing way but I hope you can understand what I am getting at....
Simply put--
I have XP drive
I buy new computer it has Win 7 drive
Xp drive becomes master, win 7 becomes slave
Will XP boot or Win 7 boot when its set as the slave drive? what about XP/7 dual boot? they are on seperate drives, will it let me dual boot?
I want my XP drive to boot.
I hope you can understand that..
If I can, I would like to reformat the win7 drive and just use that for storage. is that possioble?
Ethan
I just want some help or even an opinion, is that so hard to ask for?

Okay I read through your post a few times and I am still a bit confused about what your setup looks like. I am going to assume you bought a new computer with Windows 7 on it thus you DID NOT replace the motherboard on the old one. With that assumption, then your answer would be no, only Windows 7 would boot (and it might have some problems if you have it set as the slave drive). Windows XP from your old hard drive would not boot because simply put, the BIOS will not detect a proper boot.ini file and the hardware configuration (partitions and/or disk types) does not match up.
If you want to set up a dual boot, you would have to install the secondary hard drive (or partition the primary one) and perform a destructive OS restore on it AND find the drivers for it (if the manufacturer of the computer even supports it). When I used to work for the Geek Squad, numerous clients asked about this and the general consensus was that the Geek Squad strongly opposed it because of the drivers. Being that XP and 7 are a generation apart, the chances of the manufacturer of the computer or motherboard releasing drivers for both was unlikely. Sometimes the client would opt to have it done anyway but my former Precinct would always warn them that some features may not work correctly.
If you want Windows XP and Windows 7, I suggest the XP Mode that Windows Pro and Ultimate offers. You literally run Windows XP inside a window of Windows 7.
I DO NOT work for Best Buy. Whatever I post are just educated guesses or common sense.
