Questions on dual booting with win8 and efi

Hello folks,
I have windows 8.1 set up on /dev/sdb in efi mode and would like to install arch linux on /dev/sda
Fast startup on win8 is disabled aswell as secure boot.
Now, my questions:
1) Do I create an efi system partition on /dev/sda or do I use the one windows created on /dev/sdb?
2) Just to make sure, I still need a /boot partition outside of LUKS even when using an efi system partition, don"t I?
cheers,
StR@ng3r

For question #2 I believe the answer is yes. See here: https://wiki.archlinux.org/index.php/Dm … Partitions

Dual boot with Mavericks and Snow Leopard on Two different internal drives?

I have a late 2009 quad core Mac Pro running Snow Leopard- it has 4 internal HD's. I want to eventually upgrade to Mavericks. Before I do a clean install of Mavericks on my start up disk that has Snow Leopard OS, I was hoping I could download Mavericks and install it on another clean internal hard drive to test it out before I commit to erasing my main drive and doing a clean install. My Mac Pro meets the minium specs to run Mavericks.
If I install Mavericks on this second internal drive can I dual boot using the option key at start up and elect to either operate in Snow Leopard or Mavericks? What are the concerns or issues I might face if this is possible?
As I have Snow Leopard, I am also unable to produce a Mavericks bootable USB flash drive- the terminal commands don't work with Snow Leopard. With Mavericks installed on a second internal hard drive- will I be able to create a bootable Mavericks USB Flash drive?
Thanks for any advice.

1. Yes.
2. The Spotlight indexes may be rebuilt every time you switch OSes.
3. Yes.

Dual boot with WinXp and Arch-Solved

Hi friends,
I was using windows boot loader to boot into arch instead of grub. I used this:
dd if=/dev/hda7 of=arch.lnx bs=512 count=1
to get the first 512 bytes of the partition in which I installed arch and then added a line directing towards arch.lnx (moved to windows partition) in boot.ini. But now after reinstalling arch, when i do the same to get first 512 bytes of the partition, it generates a blank file and hence using that I'm not able to boot into arch. Grub is installed in this partition only. Any hints about this issue.
EDIT: I dont know what was the problem exactly, but after I reinstalled grub by "grub-install /dev/hda7" and then did the above command, it worked fine.

moderator comment: This is a question on Kubuntu installation but it seems to me OP specifically wants to know how to set up his partitions without harming Arch. As long as the discussion remains about Arch Linux this thread can stay. I'm going to have to move this from Installation to Newbie Corner.

Please see this. I advise you to read the links 2ManyDogs gave. You also need to give us more information about your partitions, such as what is mounted where. I suspect you only have primary partitions and will need to convert one into an extended partition.

Dual boot with archlinux and windows issue

Hi again!
This is what i did from the beginning :
windows was already installed and then i installed archlinux after shrinking the windows partition . I made a partition for boot , one for swap and one for root(i wanted to do for home too , but only 4 primary partitions are allowed) . I made the boot partition bootable , and so was windows bootable and i got the message that there are two bootable partitions so it couldn't write the partition table . So removed the bootable tag from windows and left only the boot partition bootable . I then installed the grubloader to boot partition and then i edited that grubmenu and uncomment the part where windows was like it says in wiki. After restarting i could see the menu to choose between archlinux and windows , i chose windows , i succesfully logged in and after restarting again i couldn't see the grubloader and i automatically logged in windows .
Does anyone know what might be the issue ??
Thanks !

yes i only have one hard rive , i managed to find a solution not that elegant though , i 've installed acronis os selector from windows and i can choose between windows and linux with acronis on boot . If i choose linux i get to the grub menu and i can choose between arch linux and windows . So it seems that the grub menu is still there but it doesn't appear when i boot for some reason .

Dual boot with lion and mavericks?

Hi Guys,
I want to updgrade to mavericks as well as keeping lion to run my old soundcard { no new drivers will be made } so, I'm thinking of using my external hard drive to try and install mavericks onto and Dual boot my MBP.
is this possible?
Cheers, Iain.

Hi Mate,
I'm currently backing up my hard drive and then I'm going to download mavericks.
After the download completes you get this screen:
Quit without pressing the install button. Go to the applications folder and make a copy of the installer, move the copy out of the applications folder. When the copy is done doubleclick the installer in the applications folder.

Dual Boot with Leopard and Tiger

I've got a Dual 2 GHZ Power Mac, that I recently put Leopard on. Unfortunately there's a program that I need to used for a job that doesn't play well with Leopard (yeah, I shoulda made sure before the upgrade). What I was wondering is if it was possible to partition part of the system drive and load Tiger back onto it, and then be able to boot from either Tiger or Leopard. That way I can load the programs that are only friendly with Tiger on to that partition.
Or do I need to get another drive entirely and pull the Leopard system drive out?
Thanks in advance

Hi. You can install as many different systems on different volumes/partitions as you wish. They can all be mounted at the same time, and you can select the default system to boot from in System Preferences > Startup Disc - or select at boot time by holding down the Option(alt) key as you Startup. But a system must be the only one on that volume/partition.
Where to put the 10.4 system is more tricky. If you only have one internal drive, it's possible to re-partition it live - but not really a very good idea.
It would be best to install 10.4 on a second internal drive - or a volume on that drive - or on an external FireWire drive.
Needless to say all your data should be well backed-up before starting any of this.
Rather than go through all the combinations - please post again with any detailed questions. Good Luck.

Dual Boot with Win8 on UEFI with SSHD

Hi folks!
I have a Lenovo Y40 laptop which currently has Windows 8.1 preloaded, which I unfortunately have to keep for a host of reasons. I've been meaning to install linux on my laptop for a while though, and now I finally have the time. However, I've been doing some research, and there are just too many things I don't understand that are keeping me from just jumping in and installing "on the fly".
Here's where my problems are:
This laptop has a hybrid drive in it, specifically the WDC WD10S21X-24R1BT0-SSHD (I copied this out of the device manager), and I hear linux has problems with that? Also, this laptop uses UEFI, which I have zero experience with. Lastly, I have no idea which of the many preloaded partitions (listed below) are necessary for windows 8 to boot and function properly.
List of my partitions:
Two partitions labeled "Recovery Partition" in the disk manager (one 1GB and the other 15.64 GB)
The EFI partition
A partition labeled "OEM Partition"
The partition my C:\ drive is on
This absurd 25 GB partition with the name "LENOVO" which is mounted as D:/ and has folders named "Applications" and "Drivers"
So basically, I simply do not know how to install arch (or linux in general) on this kind of a system. I'm really hoping someone can generously give up some of their time to maybe send a few links and some basic steps to get this installation procedure going.
Thanks!
P.S. I have installed Arch before, but on a BIOS system with "normal" MBR-formatted hard drives. I'm pretty good with Linux, so you can assume a fair amount of previous knowledge.

Sounds unlikely; what problems? Where did you hear this?
As for your partitions: shrink the C: partition (from Windows, defrag first) & mount /boot to the EFI partition (ie share this partition with Windows).
Leave all the other partitions intact.
Just follow the Beginner's Guide, it includes details pertaining to installing UEFI systems.

Ac100 dual booting with Android and Archlinux

Hi I am trying to install Arch on my Toshiba AC100.
I installed Android already, bit i don't know how and where to install Arch linux.
I followed this tutorial.
https://code.google.com/p/cm-paz00/wiki … Guide?tm=6
(and I made 7th partition to install Arch.)
and I compiled kernel already following this -> http://ac100.grandou.net/kerneldev?&#ma … git_kernel
and I read this -> http://ac100.grandou.net/faq?s[]=dual
but i don't know how to 'flash'!
I really need your help.;D

It's an ARM-based device, so you can't install Arch Linux, you need Arch Linux ARM, a separate distro: https://bbs.archlinux.org/viewtopic.php?id=153431

Dual Booting with the MacBook Pro

I know that on the iMac you can do a dual-boot with PC and Mac, but I am trying to find out if you can do it on the MacBook Pro. Does anyone know?

hi abbyt - Welcome to Apple Discussions!
if you mean dual-boot btw OSX and WinXP - you sure can. apple provides Bootcamp for precisely this reason and it works very well...
http://www.apple.com/macosx/bootcamp/
if you mean dual-boot btw OSX and some kind of Linux - i have less experience there, but i think its possible. perhaps the easiest way is to use Parallels Workstation (but that's not really dual booting in fact - it's virtualization)...
what "2nd" OS were you thinking about? cheers

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.

sudo make sandwich wrote:If it is possible to share ESP between OSes, how do I do this (would it be sufficent to follow this section: https://wiki.archlinux.org/index.php/Beginners'_Guide#For_UEFI_motherboards)?
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.

DUAL BOOT windows 7 and linux HELP with Current info on BIOS, MBR vs GPT, etc

I have a feeling this should be easier than what I'm making it. Please educate me on Lenovo's BIOS Setup menus, etc.
I have installed easyBCD in Windows 7, and plan to use it to set up my new boot menu with Linux Mint (and possibly other distros).
I am using a live DVD. I inserted the DVD and went into SETUP and selected to boot off the DVD drive. It started to boot into Linux and all was going well.
However, I realized that I had not checked on the Secure features (Secure Boot, EFI). So I shutdown again and went into BIOS. I went to the SECURITY menu and Disabled UEFI. Then I disabled Secure boot.
Tried to boot off the DVD and couldn't get anywhere. Kept putting me back into the window to select the boot device over and over again. THought I'd ruined my machine
Anyway, finally stumbled upon STARTUP menu, and put it into EFI Legacy, and I was able to get back into Windows 7.
Obviously before I pursue this further, I need some educaiton on your MENUS, Lenovo and EFI/Secure Boot.
I have a feeling that I can probably now install the Linux but want to make sure my settings are correct before I pursue.
Thanks, Kim
Moderator note: this thread gets more Linux-flavored with each post Moved from the "T" board to the Linux board.

Hi, thanks for ans. Your specs are almost identical to my T530 ,which I should have listed. The only diff is
I have an i7 35something processor. Same intel card, RAM and HDD, not that that should matter I'm guessing.
I purposely avoided the Nvidia card because of all the heaadaches with Nvidia.
I have to teach a class tomorrow and I need to clean up my notes. (Definitely not computer related...LOL.) I don't want to be stressed out about this during class, so I plan to wait to attempt a new install tomorrow afternoon.
What I have done is find out some more info about dual booting with windows 7. I went in to windows 7 to shrink the C: partiition and it said I'd have to reserve at least 220 GB for MS! Not what I wanted; I don't really care a thing for MS. I was born and raised on Unix and Linux; I never really fiddled with MS after the demise of MS-DOS during my college days.
Given that, and the fact that I'd lose half my 500 GB HDD to the Borg, I may just chuck the entire dual boot thing and just load Linux on it.
If you say you're running Linux on it just fine, that would be a great encouragement. No HW problems at all? Everything working fine? Which distro are you using?
I plan to test Mint, Fedora, PCLinuxOS, Mageira (sp?), saybahon (sp again?), Debian Wheezy, and even Pear, LOL. I'll keep trying till I find a distro to run on my Lenovo T530, but I'm guessing all of 'em should do okay.
I have Lubuntu I could give a spin, as well and Crunchbang and Bodhi, but they're all 32 bit. (I have an antique Dell desktop that I still use down in my woman cave.)

[SOLVED] RTC and dual booting with Windows 8/8.1

I am planning ahead of installing Arch on a windows 8.1 laptop, and need to understand whether or not the known Windows registry hack to get windows to use UTC for the RTC is still valid for Windows 8/8.1? I have been searching via google and the usual sources of information, but it is not clear to me if there are problems doing this, specifically if arch is dual booted with Windows 8/8.1 rather than older versions of the MS OS. Certainly I have used the technique without any problem in the past when dual booting Windows XP with Arch on several different machines.
Does anyone have personal experience with doing this on a Windows 8 or 8.1 machine and can report here on whether it works successfully or not?
Thanks for any advice.
Last edited by mcloaked (2014-02-11 21:16:21)

Since there were no replies at this point I thought I would just go ahead and implement the registry hack on the Windows 8.1 O/S in the laptop and see if Windows behaves. It appears to be OK, with the displayed time being correct after reboot, and time synchronisation remaining fine with no problems seen in the displayed time, although I won't be able to read the RTC directly until I have completed the Arch install in the coming week or two. I now don't foresee any issues with the time synchronisation between booting Arch and Windows 8.1 so I will mark this as solved.
Since the RTC is now in UTC then normal clock config in Arch using chrony should perform normally once the install is done and the new system set up.

[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.

Can I dual boot with MAC OS/X and Windows

What is the best way to configure a dual boot on my MAC Bookpro laptop? Also, can I dual boot Windows 8 and MAC OS?

The first alternative is a dual-boot arrangement between OS X and Windows provided with OS X.
Windows on Intel Macs
There are presently several alternatives for running Windows on Intel Macs.
   1. Install the Apple Boot Camp software. Purchase Windows
         XP w/Service Pak2, Vista, or Windows 7. For Boot Camp
         4.0 and above you can only use Windows 7 or later. Follow
         instructions in the Boot Camp documentation on
         installation of Boot Camp, creating Driver CD, and
         installing Windows. Boot Camp enables you to boot the
         computer into OS X or Windows.
     2. Parallels Desktop for Mac and Windows XP, Vista Business,
         Vista Ultimate, or Windows 7. Parallels is software
         virtualization that enables running Windows concurrently
         with OS X.
     3. VM Fusion and Windows XP, Vista Business, Vista Ultimate,
         or Windows 7. VM Fusion is software virtualization that
         enables running Windows concurrently with OS X.
     4. CrossOver which enables running many Windows
         applications without having to install Windows. The
         Windows applications can run concurrently with OS X.
     5. VirtualBox is an Open Source freeware virtual machine such
         as VM Fusion and Parallels that was developed by Solaris.
         It is not as fully developed for the Mac as Parallels and VM
         Fusion.
Note that VirtualBox, Parallels, and VM Fusion can also run other operating systems such as Linux, Unix, OS/2, Solaris, etc. There are performance differences between dual-boot systems and virtualization. The latter tend to be a little slower (not much) and do not provide the video performance of the dual-boot system. See MacTech Labs- Virtualization Benchmarks, January 2013 | MacTech for comparisons of Boot Camp, Parallels, and VM Fusion. Boot Camp is only available with Leopard or Snow Leopard. Except for Crossover and a couple of similar alternatives like DarWine you must have a valid installer disc for Windows.
You must also have an internal optical drive for installing Windows. Windows cannot be installed from an external optical drive.

Isolated dual boot with OS mavericks and mountain lion

I just created a dual boot between mavericks and mountain lion (1 physical drive with two partitions) but I'm having troubles where they each see each other. Bin/ lib/ etc are fine (i think) as they are added via environment vars but it seems as though the spotlight privacy directories are shared. For instance, I thought I could simply add the other partition to the Spotlight Privacy list, ie while using mountain lion add /Volumes/Mavericks to the privacy list. However, when I added the volume in one, it also appears in the other. Another issue I've encountered is that while compiling on ML, I was getting errors complaining about the 10.9 sdk.
So, can anyone advise on the proper way to isolate these two operating systems with a dual boot scenario?
Thanks
Adam

Create two partitions on the hard drive. Install each OS on its own partition. This will only work if the computer can be booted from either version.
