Dual boot Windows 7 (64) and Arch Linux (64) problems

Hello:
I am new to Arch Linux and just finished installing the 64bit on my laptop. It had a prebuilt Windows 7 (64) installed which I kept but split the hdd from 160Gb to 80Gb and 80Gb. I installed Arch there and set 4 partitions, all of them as Logical - a 64 MB ext2 /boot partition; a 512 MB swap partition; a 15 GB root partition; and the rest as my /home partition. My partitions look like this:
Disk Drive: /dev/sda
Size: 160041885696 bytes, 160.0 GB
Heads: 255 Sectors per Track: 63 Cylinders: 19457
Name Flags Part Type FS Type [Label] Size (MB)
sda1 Primary Unknown (27) 12889.02
sda2 Boot Primary NTFS 106.93
sda3 Primary NTFS [] 73915.11*
sda5 Logical Linux ext2 65.81*
sda6 Logical Linux 509.97*
sda7 Logical Linux ext2 15002.92*
sda8 Logical Linux ext2 57549.55*
The install was succesful(this was running from the core install cd) and I installed GRUB to my /boot but when I restarted it loaded Windows 7. I have used Knoppix USB disc to boot and see my Arch Linux install files and edited the /boot/gur/menu.lst file.
In Windows I installed EasyBCD 1.7.2 and tried to get NeoGrub bootloader working as a dual boot. I tried getting rid of the boot flag for Windows with cfdisk and setting it to my (Logical) sda5. That did not work. So far the only way I have booted into my Arch Linux install has been by going to the Live CD, choosing "Boot from Existing Linux Install" and editing the command files there.
root (hd0,4)
kernel /vmlinuz26 root=/dev/sda3 ro
initrd /kernel26.img
My goal is to get a dual boot working for Windows 7 and Arch Linux 64 and continue installing the Xorg and KDE to Arch. I just don't know what the problem is here. I don't mind reinstalling Arch if something went wrong, but I would like to keep my Windows running in order and add Arch on.
Any help would be greatly appreciated.

I ran the LiveCD and chose "Install to MBR hd0". I ended up with this:
setup hd(0,1)
Checking if "/boot/grub/stage1" exists.....yes
Checking if "/boot/grub/iso9660_stage1_5" exists.....yes
Running "embed /boot/grub/iso9660_stage1_5 (hd0,1)".....failed(this is not fatal)

Running "install /boot/grub/stage1 d (hd0,1) /boot/grub/stage2 p (hd0,1) boot/grub/menu.lst".....failed
Error 31: File is not sector aligned
My entry for Windows into the menu.lst looks like this:

Dual booting Windows 8 and Arch Linux with UEFI

Hi all!
I'm trying to install Arch Linux on my computer where I already have Windows 8, and I'm getting a little stuck when it comes to the partitioning.
Following the beginner's guide and the method here: https://wiki.archlinux.org/index.php/Un … n_in_Linux for setting up the partitions properly, regarding UEFI. My problem is that when using cgdisk to set up a new EFI system partition (ef00), I get an error message when trying to write the partition table (just saying that something went wrong). I figure the problem is that I already have a partition like this (correct me if I'm wrong), but it really looks like it succeded (see info below). So my question is: How do I preceed to keep my Windows 8 installation happy, but installing Arch? Do I remove the old EFI system partition and create a new one, or is there some method that allows me to edit the already existing one, to allow me to dual boot Windows 8 and Arch?
My partition table now looks like this:
Part. # Size Partition Type Partition Name
1007KB free space
1 500MB Windows RE Basic data partition
2 300MB EFI System EFI system partition (this one was already present on my system)
3 128MB Microsoft reserved Microsoft reserved partition
4 63.5GB Microsoft basic data Basic data partition
8 512MB EFI System EFI System partition (this is the one I tried to create when I got the error message)
5 29.5GB Linux filesystem Arch (this is where I was going to put my Arch installation)
6 22GB Windows RE Basic data partition
7 1024MB Windows RE Basic data partition
615KB free space
Just for the record; I only created partition #8 and #5.
Any help is appreciated! And sorry for beeing a total noob, but I really suck at this.

There's really very little to do to share an ESP between OSes. Most OS installers will auto-detect the ESP and use it. Problem solved. For Arch it may be a bit more effort just because Arch uses a more hands-on installation process, but I've only done a couple of Arch installations, and the last one was several months ago, so I don't recall the details clearly enough to comment.
And how big will the partition need to be? The beginner's guide says 512MB or higher.
I don't know what was in the mind of the author, but my guess is that's because that's roughly the cutoff point where mkdosfs starts creating FAT32 by default rather than FAT16. The ESP is officially supposed to be FAT32, not FAT16, although FAT16 usually works OK. It's also possible to create FAT32 on smaller partitions by using an explicit option to mkdosfs ("-F 32").
The optimal size of the ESP depends on the files stored on it. If you don't store your Linux kernels, something as small as 100MiB is usually adequate; but a few Linux kernels and their initrd files can consume twice that amount. My own recommendation is for the ESP to be 200-500MiB.
The only error message I got from cgdisk is "Problem saving data! Your partition table may be damaged!", however booting Windows again works fine. Parted did not complain about antything.
Use the "verify" function in cgdisk. That will reveal any problems with the data structures. If a verify turns up OK, then that means that cgdisk ran into some sort of disk problem. Running gdisk rather than cgdisk and using the gdisk "w" option (without making any changes) may produce a more helpful error message.

[SOLVED] Dual boot windows 7 and arch Linux with seperate hard drives

Ok so I'm stuck trying to get my computer to dual boot windows 7 and arch. They are installed on different hard drives and I have grub 2 as the boot loader. I can't find any tutorials on how to do it with seperate hard drives I know how to do it if they are on the same hard drive. Also I want windows on the "first" hard drive how do I check to see which one it considers the first?

Not from the BIOS. He would need to physically open up the computer and switch the cables between them (or add another drive).
There's no actual performance increase in changing this order. Performance increase is when you have the partitions as close to the beginning of a HDD as possible, where the platters spin faster (basic mechanics, not to be confused with CD/DVD, which are being written from the inside-out to prevent errors after extended usage), and it especially doesn't apply to SSDs whatsoever.
You may be right about that. I remember I had to do this a while back but I probably switched the cables. It also messed up the drive mapping in Windows 98 if I remember correctly.

[Solved]dual boot windows 7 and arch linux

I have successfully installed arch linux dual boot with the original win7 on my PC. If I only use linux, then the system works well. The problem is that once I boot into Win7 then after reboot, the linux boot manager will stop working and the system always boots into windows automatically. My guess is Win7 automatically repair the boot loader.
My current solution is whenever I have finished using Windows, I'll boot with my linux USB installation, and run "gummiboot --path=/boot install". Afterwards, linux will work fine. But I believe there must be a better solution. Any help will be appreciated.
I have UEFI board by the way.

Thanks for all your help first! I have tried Head_on_a_Stick's suggestions as the first step. Here is what I did. I have created :
$ cat /boot/loader/entries/windows.conf
title Windows
efi /EFI/hidden/Boot/bootmgfw.efi
The window boot path was :
/boot/EFI/Microsoft/Boot/bootmgfw.efi
and I changed
/boot/EFI/Microsoft
to
/boot/EFI/hidden
After reboot, I clicked 'Windows' option on the linux boot manager. Below are the error messages:
Windows failed to start.
File: \EFI\Microsoft/Boot/BCD
Info: An error occurred while attempting to read the boot configuration data.
Any idea what goes wrong?
I'll try other suggestions soon. Thanks all of you again.

Dual Boot Windows 7 and Arch with Shared NTFS partition.

Hi everyone,
I want to dual boot windows 7 and Arch Linux.
Here's the problem... my hard drive isn't the biggest. I want to store all my music, movies, pictures, and documents on partition that both linux and windows can access seamlessly.
I want the partition to be NTFS. -- (the programs that map an ext4 drive to Windows are trash).
Here's what I think I need.
30GB NTFS to Windows.
30GB ext4 to Arch Linux
The remainder (190ish GB) to Shared Data.
I don't want the swap partition because I have a SSD and 4GB of RAM.
What is the best way to setup my partitions? And is this even possible?
Thanks!

Not a problem. I would create:
First of four primary partitions for windows.
Second of four primary partitions for /boot
Third of four partitions is an extended partition encompassing all the space not used by the first two partitions.
Put everything else inside the extended partition.
Mine is a bit more complicated, but this should give you an idea:

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.

I want to dual boot windows 7 and Arch with an HDD caddy.

I am thinking of two possiblities with this scenario. I want to first leave my windows 7 install on the hard drive that came with my laptop, and leave that HDD where it is, but in a few days, i'm getting a caddy so i can switch my optical drive for another HDD, which is going to be a 250gb. On the 250, i want to experiment with arch, and maybe other linux distros, so i can get a nice feel for linux once again, it's been about 2 years since I've played with it. What i am hoping to maybe do is switch those hard drives out, if I can get a linux install i feel 100% comfortable with, and running the windows HDD in the caddy, and the linux HDD installed in the motherboard.
I just have a few questions though. First, is it possible to boot Arch when it is an HDD caddy? and second, would windows possibly work if i moved that hard drive into the caddy later?

perpulstuph wrote:First, is it possible to boot Arch when it is an HDD caddy? and second, would windows possibly work if i moved that hard drive into the caddy later?
Yes, and yes. Both should be quite easy.
You should be able to set you BIOS to boot from one or the other - or alternately you can chainload windows from a linux boot loader quite easily (if/when linux is on the drive that the BIOS has selected to boot).

Dual Boot Windows 8 and Linux?

I have (UEFI System) an ASUS K55A UEFI motherboard laptop that came factory with Windows 8. I would like to install backtrack linux and Windows 8, but before I go screwing up my laptop, I want to see if this would be at all possible. I would use a virtual
machine, but I need Backtrack Linux on a physical machine for testing purposes as I am taking a course in computer forensics, and I want to test cracking my home wi-fi. My processor is an Intel Core i5 2.5 ghz with a 500 GB HDD and 8GB DDR3 RAM. Any insight
on this would be appreciated. Thank You.

Dual booting win 7 and arch: cannot install grub to partition

I have read the arch wiki page on dual booting and several other sources on line, but I am still struggling to get this to work.
I am trying to dual boot arch and windows 7 on my lenovo ideapad s205. the machine comes with windows 7 pre-installed.
I shrank the win 7 partition and added an extended partition with 3 logical partions for /boot, swap, and /.
I am able to install and run arch by installing grub to the mbr. when I do this, though, I cannot boot windows. (the windows section of grub menu.lst is uncommented and points toward hda0,0. I have tried hda 0,1 as well).
I have also tried to use the windows boot loader to load arch, as described in the arch wiki page on dual booting. The problem here is that, taking this approach, I should install grub to my /boot partition, but when I try to do this, the installer only allows me to install grub to sda or sdb (the usb stick).
I have read that grub should be able to boot linux from a logical partition. Is this so?
Is there something wrong with the arch installer that it is not giving me the option of installing to a partition rather than the mbr, or is this a problem with my partition scheme, or something else?
I am tempted to remove lenovo's recovery system, but on the other hand, I have already needed to use it several times while monkeying around with installing arch.
Thanks for any help.
UPDATE:
I now have the laptop dual-booting win 7 and arch. My solution ( adapted from here: http://helms-deep.cable.nu/~rwh/blog/?p=177) was to:
1. installed arch on the partitions I had created for it, but skipped the "install bootloader" stage.
2. in win 7, I downloaded and installed EasyBCD and made an entry for arch in it. I checked the option to "Use EasyBCD's copy of GRUB"
3. When I restarted, I got a grub error because the entry in grub's menu.lst was pointing at the wrong partitions for the kernel and root.
4. So I went back into the arch live disk, mounted the boot partition and edited menu.lst.
Now when I start the laptop, the windows boot loader starts and I can choose between win 7 and arch. when I select arch, grub4dos starts and gives me the option to start arch. this is not particularly elegant (nor is it fast), so I think this solution is less than ideal, but it does work.
I'd be interestd in any thoughts about what went wrong and what a better solution would be.
thanks.

Is this a typo in your post or how it was in menu.lst? Surely it should be hd0,0 and not hda0,0? The entry I have in my menu.lst is as follows:

Windows XP and Arch Linux

How do I install both Windows XP and Arch Linux on my system? I want to be able to boot either of the two from a menu that loads after the bios. I have created 4 partitions (NTFS, linux root, linux swap, linux home) and installed Windows XP on the NTFS system, as well as Linux on the other partitions. How do I go about the booting process? Are there any better ways of doing this than as above?

Just add the following in your /boot/grub/menu.lst

I assume from your description that you installed XP on the 1st partition of your 1st disc. If not, replace hd0,0 according to your setup.
kirkl_uk wrote:PS How do I make a user supervisor in Arch Linux? When I try and reboot under my made user, I do not have sufficient rights.
Just add that user in the root group in /etc/group. Or you can install sudo & 'man sudo' for details.
However, believe me, you don't want to do something like that. In windoze if you try to delete, ie the windows folder through explorer it'll stop you, pointing that this is evil. In linux you can easily call a 'rm -rf /' (as root) and wipe your disc out .
So better stick to a non-root user for everyday usage and su (or sudo) when you need root-access for a task.

Y500 dual boot windows 8 and fedora 19 problem

I bought a y500 two days ago and i wanted to dual boot windows 8 and fedora 19, so here's what i did
1. downloaded fedora 19 (x64) iso from the fedora website.
2.made a live USB using live usb creator.
4.opened disk management utility and shrunk the c drive (windows 8 was installed here) by 100 gb and kept the 100gb unallocated.
3. started the laptop with novo button, changed the bios config to boot from usb.
4.installed fedora from usb, selecting the 100gb unallocated memory for installation
5.restarted the laptop.
now the problem is fedora works perfectly but when i try to boot windows 8, the following error is shown.
windows failed to start
file:\BOOT\BCD
status: 0xc0000225
info:the boot configuration data for your PC is missing or contains errors.
i am guessing the fedora installation overwrote the boot files of windows and
i have not taken a backup. please help

hi,
I have a Y500 and I wanted to dualboot fedora 19 with windows 8, this proved to be unsuccessful. I had made a repair disk before the process (but not a set of recovery disks unfortunately >.< ). now I inserted the repair disk and selected the automatic repair option, it showed a message that auto recovery has failed. now when I pressed the NOVO button and selected the system recovery option, it does not go into the OKR menu but continues with the normal booting process. Can somebody guide me or give links where I can find step by step instructions to making OKR work and reset my laptop to factory settings? PLEASE help As Soon As Possible
NOTE: I did resize the windows 8 os partition but the recovery and the lenovo partition are still untouched

Dual Boot Windows 7 and solaris 10

Can some body guide me how to dual boot windows 7 and solaris 10?
Thanks

First partition your harddisk with at least 2 primary partitions, one for windows and the other for solaris if you only have one harddisk. It would be a good idea to create an additional small boot partition as the first partition as well if you intend on using an independent boot loader but it really depends on what your machine is capable of. For example, if you have multiple harddisk and your BIOS supports it, then you could just install each OS onto its own harddisk and use the BIOS function to disable/boot off specific harddisk. Otherwise, if you only have one harddisk and created multiple partitions, install windows7 first followed by solaris10, obviously installing into different partitions. If you have created a boot partition, then you can install the boot loader into that dedicated partition.

Re: Tecra S11 - Dual boot Windows 7 and XP

I have installed Windows 7 (from the hidden recovery section of the hardrive) on my new Tecra S11. I would like to know whether I can use the Windows XP
recovery media provided by Toshiba to create a dual boot Windows 7/Windows XP rather than reverting to XP?

You can create dual boot but not using two recovery images. Recovery image can be used for first OS installation. You cannot define on which partition the recovery image will be installed. It will always be installed on first partition.
I recommend you to do follow:
-at first install WXP using original Toshiba recovery disc
-Windows 7 install using Microsoft installation disc
I have done the same on my Satellite A300.

Windows 7 and Arch linux dual boot problem

hey guys I had an issue with windows 7 dual booted with arch and i was just wondering my windows 7 crashed. I had Reinstalled windows OS and all my partitions are set up but now when I try to boot up arch I cant at all cause windows Boot took over and i have no way of getting into arch is there anyway i can fix this or maybe reinstall arch without loseing my home folder with all my data, or is there just and easyer way to fix this issue im stuck. thank you all for your support as i am a noob

You need to re-install grub. When you reinstalled Windows it will overwrite grub preventing you booting Arch. You'll need to boot from a liveCD and chroot into your Arch installation. details for recovering grub are in the wiki - https://wiki.archlinux.org/index.php/GR … stallation
