T420 Dual Boot Trouble 7 & XP

I have a Think Pad T420 with dual boot option of Windows 7 Pro and Windows XP Pro both 32-bit. However for me to boot into Windows 7 I have to set the SATA configuration in the BIOS to AHCI Mode, but that will cause the XP to BSOD with the error of unable to detect hard drive. I change the SATA configuration to Compatibility and Windows XP can boot successfully but Windows 7 BSOD with the same error. I cannot seem to find the right driver for the AHCI chipset for Windows XP. If anyone could offer any assitance, that would be great.

It'll be the Intel Rapid Storage drivers for XP to work in AHCI mode.

Arch and preinstalled windows 7 UEFI dual boot troubles

Hi guys, I have a UEFI pc already with windows 7 on and want to dual boot arch. Problem is the current uefi partition is only 100mb and whenever i try to install a bootloader in the arch install it gives the message 'not enough room on partition'. is there a way i can increase the current uefi partition size without effecting the windows install?

Try checking how much free space you actually have on the ESP. 100MB is smaller than most people here recommend, but it should be big enough to hold the Windows boot loader, a Linux boot loader or boot manager, and at least two or three (probably more like ten or fifteen) Linux kernels and initrd files. If the 100MiB is nearly used up, then that suggests that something unusual is chewing up a bunch of space, and you can probably delete those files. This is just a task of routine file management -- identify what's consuming the space and delete anything that you don't need. The trick is figuring out what you don't need, so if you're uncertain of something, post back with details (for instance, "I've found 70 1MiB .png files in the Foo/Bar directory; do I need them?").
If something is legitimately consuming that much space, you can either create a second ESP (although that could cause problems down the road if you need to re-install Windows) or resize your partitions. Chances are you've got a Windows partition that immediately follows the ESP. Resizing it so you can increase the ESP's size is possible, but will require resizing the Windows partition from the front. This is risky and is likely to be time-consuming, so be sure to back up before you do it. Another possibility would be to create a larger ESP elsewhere on the disk, copy the contents of the first ESP to the new one, and delete the original. The 100MB of unused space would be wasted, or maybe you could find a way to use it (swap space comes to mind, although 100MB is tiny by modern swap space standards). On a modern disk, 100MB of wasted space is likely to be trivial -- for instance, on a 1TB disk, 100MB is just 0.01% of the total disk space.
As cfr says, some boot loaders/managers, such as rEFInd and GRUB, enable you to load your kernels from something other than the ESP. Thus, if you're running out of space because you've got big kernels or initrd files, you could put them elsewhere and use just a small amount of space on the ESP for the boot loader/manager.

Trouble dual-booting Mac Pro after moving - Boot Camp

Here's the story: My wife and I just moved a few miles away, and I transported my "late 2005" Mac Pro carefully on the front seat, on its side. Upon arrival, I am having great difficulty booting up.
Generally, I dual boot into either Snow Leopard or Windows XP. Here's what has been happening since the move:
I boot holding down the Option key. At this point, I have mouse movement, but no activity on the screen for about 5 minutes. When my hard drive options finally appear on the screen, (mouse movement is still normal at this point), or I can Left/Right Arrow between the two operating systems... no problem. However, as soon as I either click on the desired icon, or hit the Enter key, the mouse freezes on the screen and stays that way for perhaps 10 minutes or so before Mac OS starts up. Then operation seems normal.
But when I try booting into Windows XP, it spontaneously reboots into the Boot Camp screen... again very, very slowwwwly.
Has this ever happened to you? Any suggestions on how to troubleshoot/resolve this problem?
Thanks in advance for your time and experience.
Eddie

Begin with this:
Mac Pro came out in Aug 2006, so the fact you run Windows, you have later than any Late 2005 (which referred to PowerMac and G5s)
Normally I would travel with the hard drives in boxes, removed.
XP and also Windows 32-bit any version only offers 1.9GB usable RAM.
Depends on where XP is, on the same drive as OS X? or on its own?
Try check the drive is seated tightly.
Run chkdsk
Boot XP CD
Clone Mac OS? so you have an image if needed.
Same goes for XP.
And if you set XP as the default boot OS?

Troubles in dual boot system after BIOS update

Hello:
PC: Thinkpad T500
1. I had for one year Linux Fedora 10 and Vista Ultimate working in dual boot with Grub, no problems at all.
Three days ago Lenovo support recommended I update my BIOS from 2.07 to 3.12, as I had some intermitent Sleep problems in Vista. Then my problems started.
2. First, after updating the BIOS from Vista (dowloaded the exe, double clicked it, gone through the whole sequence with no errors), upon the first restart, the screen was black and I couldn't get in BIOS with F1 and the same happened during other power-off/power on sequences.
3. Now, I've discovered that the best I can do is wait for 10 min after restart in order to get a prompt from ThinkVantage, then Grub boots only the Linux system which works OK.
4. I can't get the dual boot message from Grub, and I can't get any Windows DVD to be taken at boot (I've got full backups from both Control Panel and from ThinkAdvantage backup facility) in order to ru Windows repair.
5. I can go during the ThinkAdvantage to BIOS, the new version seems there (not sure if completely operational), but whey can't I see it with F1?
Is the presence of ThinkAdvantage something special in dual-boot systems or wrt to the BIOS install? Should I do something special about it? I just don't know.
Any ideas?

Strange. I don't have a clue, but I have seen posts here that recoverd from strangeness after a BIOS update by unplugging from the AC mains, removing the battery, and then pressing the power button several times. The last time, hold the button for 10 seconds or so.
That is really a total WAG, but maybe worth a try.
Out of curiousity, what do you see when grub finally loads. I take it that it isn't your original boot menu. Do you have grub installed in the MBR, the boot sector of the Linux partition, or both? Is the Linux partition (or Linux boot partition if you have boot + root) the 1st one on the drive, or _after_ the vista partition.
[edit] You didn't ask, but IMNSHO multibooting a modern laptop isn't really the easiest way to run multiple OSs. I run Linux, Solaris, and OS X in VMs under Win 7 on my T400. They run well, and that approach avoids issues like you are having. The Lenovo ThinkVantage boot-time stuff and R&R are rather fragile. Changes in partitioning and MBR configuration can break them. BIOS and other updates, and Windows repairs can break the multi-boot setup.
There are several ways to set up VMs, but VMWare Player is what I use. The latest version is free and quite usable.

T420 [4236] video drivers lost after booting Win 7 [dual boot]

Never saw this before. Dual boot Win 7 and XP. Neither can see each other so no cross contamination.
Video - NVidia NVS 4200M is what shows under display adapters.
Reboot XP, no issue.
Boot Win 7, then return to XP, video shows as [returns to] standard vga drivers and have no dual monitor function. If I try to reinstall drivers and point to them, it is not accepted. Only thing that works is to run the original driver download exe [NVidio Optimus - 83de45ww.exe] to uncompress files and then automatically run driver install. If I try to run previously uncompressed files, it does not work. This is the strangest thing I have seen in a long time.
Is this possibly a AHCI thing as I just got this booting in AHCI? Do not remember this happening in compatibility mode but it is possible that it was as I am just setting up this machine.

Do you have auto-detect switchable graphics enabled in BIOS?

Error with dual boot Win 8/OL6 R3

Hello,
I am hoping to discuss this with someone who has experience with this configuration. My goal is to get Oracle Linux dual booting on my windows 8 machine.
I have installed OL but I am having trouble getting it to dual boot win8/OL using the windows boot menu. Whereas windows 8 boots as expected, the Oracle Linux option gives me the error:
"+Windows failed to start. A recent hardware or software change might be the cause...contact you system administrator or computer manufacturer for assistance+
+File:+ \NST\nst_linux.mbr
+Status: 0xc000007b+
+Info: The selected application or operating system couldn't be loaded because a required file is missing or contains errors.+"
Here are some details of the scenario:
- Documentation followed: Red_Hat_Enterprise_Linux-6-Installation_Guide-en-US.pdf
- Hardware: Dell Precision M4700 64 bit UEFI
- OEM installed/Default OS: Windows 8 Pro 64 bit
- Installation source: OracleLinux-R6-U3-Server-x86_64-dvd.iso (written to DVD)
These are the broad steps I followed:
In windows 8
I:
- downloaded the Linux ISO software. The checksum on the download matched
- wrote the ISO to a bootable installation disk
- created a new 344gb partition for Linux using the DOS DISKPART command - partition 7
Linux Install
- I booted using the Linux installation DVD and started the installation
- When Installing Linux partition 7 became a 500mb system partition and partition 8 became the 343 gb Linux partition
- I manually created the boot partition as ext3 (because the pdf I was following said "+If your 64-bit x86 system uses UEFI instead of BIOS, you will need to manually create a /boot partition. This partition must have an ext3 file system. If you choose to partition automatically, your system will not boot.+"
- I installed the boot loader on sda7. I selected “First sector of boot partition - /dev/sda7”. I assume this installs separate GRUB boot loader on the Linux partition (7) – which will then be 'chain loaded' from the windows boot menu. Put another way, it will boot with the windows boot manager, which will give me an option to chain load the Grub boot loader, which will then run Linux...
- I chose the desktop installation
- The installation reported that it completed successfully
I successfully booted back into windows:
- I used easybcd to edit the microsoft bcd and successfully created a boot menu for Oracle Linux. I used the legacy grub because the Linux documentation says "+Note that the version of GRUB in Red Hat Enterprise Linux 6 is an old and stable version now known as "GRUB Legacy" since upstream development moved to GRUB 2.3 Red Hat remains committed to maintaining the version of GRUB that we ship with Red Hat Enterprise Linux 6, just as we do with all packages that we ship.+".
- After installing Linux and updating the BCD, the BCD now looks like this:
Windows Boot Manager
identifier {bootmgr}
path \EFI\Microsoft\Boot\bootmgfw.efi
description Windows Boot Manager

device partition=C:
path \NST\nst_linux.mbr
description OracleLinux
I'm not sure the BCD entry is correct. I assume that this entry should be pointing to the nst_linux.mbr on the Linux boot partition. However I have verified that this file exists in windows 8:
C:\NST\nst_linux.mbr
I haven't been able to exactly confirm how the boot process should work i.e. whether this file should actually be in the Linux boot partition (as opposed to the windows c drive) and whether the BCD should also point to the Linux boot partition when referring to this partition.
As I mentioned above, I now have the windows boot menu with Windows 8 (which boots successfully) and Oracle Linux (which gives me the error see below for complete wording**). Is the Real-mode Boot sector wrong? Should it point to the Linux boot partition? Is it a problem with my UEFI disk? I don't think it should be because this version of Oracle Linux supports UEFI and my hardware is UEFI.
Has anyone carried out a similar win8/OL dual boot?
2001
** Complete wording of the Linux boot option in the windows boot manager:
Windows failed to start. A recent hardware or software change might be the cause. To fix the problem:
1. Insert your Windows installation disk and restart the computer.
2. Choose your language settings, and then click "next".
3. Click "Repair your computer".
If you do not have this disk, contact you system administrator or computer manufacturer for assistance

Hi,
Here are my responses:
*[asmirnov]* Could you please confirm, I just want to see if I got it right the first time -
*[2001]* I'm happy to share my progress
Q1)
*[asmirnov]* You did create a partition (where you would install Linux) from Win8, correct?
*[2001]* Yes. I used diskmgmt.msc to create a separate partition. I didn't format the partition because the Linux install doesn't want that, it creates and formats the partitions in the unallocated partition
Q2)
*[asmirnov]* You use GRUB (not GRUB2)?
*[2001]* I'm not sure where you were asking about, so I hope my answer here covers all possibilities you may have meant.
I was using the windows 8 boot. I wanted to chain load to the boot loader in the Linux Partition. It is interesting what the Linux install did with my partition, it created 2 partitions in the unformatted partition. 1 was a bootable partition and the other was the Linux partition. The details were:
2 sda’s (a boot / ext4 and a VolGroup (vg_linuxlocalhost)/ physical volume (LVM) ). In the VolGroup it created 3 lv’s, lv_root, lv_home and lv_swap. I understand that this is all normal.
I followed the documentation note which said "To configure the Red Hat Enterprise Linux boot loader to chain load from a different boot loader, you must specify the boot drive manually. If you chose any of the automatic partitioning options, you must now select the Review and modify partitioning layout option before you click Next or you cannot specify the correct boot drive"
So there was also the note in the documentation that said "Note that the version of GRUB in Red Hat Enterprise Linux 6 is an old and stable version now known as "GRUB Legacy" since upstream development moved to GRUB 2.3 Red Hat remains committed to maintaining the version of GRUB that we ship with Red Hat Enterprise Linux 6, just as we do with all packages that we ship." I didn't install any bootloaders manually (either the windows 8 OOTB default that came with my machine or the Linux one), I just took the defaults. I'm wasn't sure how to access the Linux partitions once it is installed, so I can't confirm it was the legacy GRUB in the Linux boot partition, but I believe this note is saying that it OL6 does use the legacy grub. I believe GRUB Legacy is version .97.
Q3)
*[asmirnov]* Which version of Linux exactly did you use, was that Oracle Linux or you used one from RedHat directly? What is the kernal version?
*[2001]* I used "OracleLinux-R6-U3-Server-x86_64-dvd.iso.sha1sum" from the mirror site http://mirror.aarnet.edu.au/pub/oraclelinux/OL6/U3/x86_64/. According to the release notes at: https://oss.oracle.com/ol6/docs/RELEASE-NOTES-U3-en.html the kernel is
- Unbreakable Enterprise Kernel Release 2 [kernel-uek-2.6.39-200.24.1.el6uek]. Installed and booted by default
- Red Hat compatible Kernel [kernel-2.6.32-279.el6]. Installed by default
Note: By default, both the Unbreakable Enterprise Kernel and the Red Hat Compatible Kernel for the specific architecture (i386 or x86_64) are installed, and the system boots the Unbreakable Enterprise Kernel by default. If needed, /etc/grub.conf and /etc/sysconfig/kernel can be modified to make the system boot with the Red Hat Compatible Kernel by default.
Regarding your follow-up point that "Microsoft blocks 3rd party chainloaders from the BCD menu for UEFI machines. We are researching workarounds, none have presented themselves as of yet.", I'm not sure it actually blocks it, but it certainly isn't a straight forward process.
I have actually abandoned my attempt to get the dual boot working. It is a real shame because I wanted to do it for my own satisfaction.
I am now using Oracle Virtual Box as suggested by others, include Dude earlier in this thread. This has given me confidence that I was doing all the right things because the install worked first time without any problems. The virtualization is much simpler and I have had no problems so far.
Fusion
As for your point about the fusion middleware and OL5. I am looking at Oracle SOA with is part of the Fusion brand. I think that the latest SOA components will work on OL6 - but I have yet to try it. Following the certification matrix can be a little difficult. So as I indicated above, my current thoughts are to use the Oracle Virtual Box with Linux r6 u3 and to install the SOA components on that when I get chance. The alternative is using the pre-built virtual machine it has Linux and SOA (it might cover your stack too, or there may be another one that suits you better on the site) http://www.oracle.com/technetwork/middleware/soasuite/learnmore/vmsoa-172279.html. Note that this is still on OL5.
I hope this helps.

Dual boot , windows 7 keep restart after select from grub section

Hello everyone, i am new here.
I want to make a dual boot in my computer.
I am using a same hardisk to install both OS.
1st, I install arch linux , after install working well from grub.
2nd, I install windows 7, after install , it skip the grub section , directly load windows 7.
I boot my archlinux live cd.
Go to grub .
type root (hd0, and press tab to make sure my partition.
setup (hd0).
The grub section was recover and success to login arch linux.
but fail to login windows 7 , then i modify /boot/grub/menu.lst . modify the windows (hd0, 1).
My trouble probem is here, after i select the windows section , my com just like restart computer.
Even i try change to (hd0, 2 or 3 ) also same problem, windows 7 restart computer.

I have try to install dual boot for more than 5 time, first i install windows then only come to arch linux, but always fail to boot up windows.
Thank for helping me ^^
This is my fdisk -l
I have 2 hardisk, but i install both Os in the same hardisk.

Will upgrading to OSX Mountain Lion erase my rEFIT dual boot Windows?

Hi All,
At the suggestion of one of the users in a different section of the forum, I am posting my question here in hopes of finding someone who might have already done this upgrade and can speak from experience.
I have a MacBook Air that is currently setup to dual-boot OSX Lion or Windows 7 with Boot Camp. The Windows 7 was a requirement in order to be able to use my laptop for work. I want to upgrade to Mountain Lion but I also don't want to erase the partitioning on the hard-drive and I want to keep my Windows 7 installation intact. If I choose to upgrade (instead of a clean install) will this delete the Windows partition and wipe out my disk or will it retain my dual-boot option as it currently is?
Thanks for your help.

Then wait on update, and plan to (goes without saying hopefully) to have backups of both that you can always restore. Especially as this is a work computer in essence.
Lion had trouble until 10.7.1 and the Lion 4.0 Windows Support Software itself was buggy for those that were installing Windows (or upgrade their boot camp drivers with Lion's).
Until people look at the Lion Recovery partition and whether that changed in size or something, or other changes to the partition tables.
WinClone 3 and CampTune can both help preserve your installation and Carbon Copy Cloner to make bootable backup of Lion and Lion Recovery, in addition to TimeMachine. (TimeMachine has been improved and more flexible).
And store your ML install package somewhere - given how slow it is DL'ing I'd wait days to even bother.

Edge e520 i5 UEFI/GPT Dual boot Windows/Ubuntu

Hi!
I have an Edge e520 1143GVG. It has an UEFI-Board with Win7/64 on MBR-Harddisk.
What I want:
GPT-Partition scheme and dual boot Windows 7/64 and ubuntu 14.04/64.
I managed to backup the partitions on an external HDD, install GPT on Harddisk, recopy saved Partitions and have now a fully running Win7/64 on GPT-System (it wasn't that easy as it seems here).
Next Step is to install Ubuntu on a separate Partition. I took a standard Ubuntu boot-CD, startet the pc with that boot disk (Board-Settings: UEFI/BIOS "Both", UEFI First) and installed Ubuntu without any trouble. Unfortunately no boot entry has been generated, so I tried to add one with EasyBCD. That doesn't work, an error is shown like "Windows cannot be startet, no valid file /NST/grub.mbr" or something like that.
I think the reason is that the cd booted in BIOS Mode, not UEFI. If I set board setting to "UEFI only", the boot CD will not start. So I built a bootable Ubuntu USB-Flashdrive with GPT-Scheme, but it didn't start as well.
After that I updated BIOS hoping UEFI-Boot from external devices will be possible then. It isn't.
The e520-board seems to be outdated or faulty, it is not possible to boot from USB or CD in UEFI-Mode.
Does anyone knows a solution? Will Lenovo update the BIOS?
kr,
Bernd Hollermann, Germany

I have to update my problem:
booting in gpt/uefi-mode is impossible from usb-key, but is ok from DVD. I managed to install Ubuntu now, everything runs well, after I took a 64-bit version on a dvd.

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

Deleting dual boot OS

i only found one post that was somewhat applicable to my issue of removing a dual boot (http://forums.lenovo.com/t5/ThinkStation/Thinkstation-E20-Dual-boot-from-Windows-7-into-XP/m-p/21871... and that led me on a merry chase. if this is useful to anyone else, great - if posting a solution as an FYI is inappropriate and i should wait to reply to someone with the same issue, pls let me know
the situation: my former IT guys installed W7 Pro x64 (thx, Lenovo, for the free upgrade from Vist Business ) on a new partition alongside XP Pro x32 and it worked great, but i only kept using XP for my !@#$%^ genius scanner, which i have never gotten to run under XP Mode/Virtual PC in W7.
one day, after several months of XP inactivity, i decided to boot into it for some reason and had a BSOD. so then i set out to just eradicate the offending OS and its partition...simple, right? not in this case. i found the guys had put the W7 OS onto a logical drive not a primary:
Local Disk (C
156.71 GB NTFS
Healthy (Boot, Page File, Crash Dump, Logical Drive)
my boot.ini was on the XP partition and W7 uses bootmgr so i poked around and found that EasyBCD should take care of the issue by copying the boot.ini info to bootmgr on C:\ through this link in the SevenForums:
http://www.sevenforums.com/tutorials/209885-bootmgr-move-c-easybcd.html
again, not so easy. i could not move the bootmgr because of the logical status of the partition and also because the partition wasn't set to active; i converted the partition to active with no troubles under the native Disk Managment but failed when i tried to convert the partition to primary.i feared having to do a wipe and reinstall to tidy up as i saw some (forums unnamed) folks advocating.
i looked into it a bit further and found that i needed to use use a partition tool from bootable media (i used a CD with EaseUS Partition Master - the freeware version ) to convert to primary at boot and then i used the above link to copy the bootmgr to C:\ with EasyBCD
now my OS drive looks like so (the partition is large owing to the GIS files that like living there):
Local Disk (C
226.71 GB NTFS
Healthy (System, Boot, Page File, Active, Crash Dump, Primary Partition)
that solved the problem of the W7 OS being on an inactive, logical drive instead of an active primary - and in future if i set up a dual boot for any other OS, i'll make sure the disk is set as primary before i install and the backwater IT guys here will never touch my machine again

[SOLVED] MacbookPro 8,1 13" - Dual boot with Mac OS X #rEFIt

Hi everyone, I want to share my experience and request for help regarding my attempt to install Arch on my MBP 8,1. I can't count the times I've tried to install it this week.
What have I done?
So I followed the Beginner's Guide to aid me in the installation, with some exceptions:
* I used Linux Mint 14 to use GParted. The reason I used it is because rEFIt won't sync the GPT and MBR tables properly when I try and use `mkfs.ext4 /dev/sdaX` inside the Archiso. With Archiso, the filesystem types are considered to be "Unknown" (#wtf no. 1), whereas with Mint that doesn't happen.
* In fstab I had something like:
# /dev/sda4
UUID=c35d9121-a3f1-4cd6-ab53-61fe0f474eee / ext4 rw,noatime 0 1
# /dev/sda5
UUID=390185f6-6d55-430c-a9ba-d3d0b4c7798b /home ext4 rw,relatime,codepage=437 0 2
The wiki mentioned the noatime and codepage flags for the respective partitions and so I complied.
One thing to notice is I have no /boot mount because syslinux apparently doesn't like that.
* Installing syslinux (along with gptfdisk), I issued:
syslinux-install_update -iam
, and reviewed /boot/syslinux/syslinux.cfg like this:
LABEL arch
MENU LABEL Arch Linux

I used UUID's to avoid the mess on sdaX discrepancies.
Results
* rEFIt correctly shows Arch as a boot option. It boots correctly to Syslinux.
* The kernel load fails due to something like:
Unknown filesystem 'vfat'
... and/or ...
Waiting 10 seconds for /dev/sdaX ...
This stroke me as #wtf no.2. VFAT?? Has anyone experienced this before?
For now this is all I have. I was hoping the community could give me helpful pointers on solving this as I intend to contribute with documentation on this setup in the wiki.
I'll be updating this post with newer information. Thanks for helping!

I don't have much experience with SYSLINUX or booting a Mac in BIOS mode, but I can help answer a couple of your questions and offer some alternative approaches....

Hi everyone, I want to share my experience and request for help regarding my attempt to install Arch on my MBP 8,1. I can't count the times I've tried to install it this week.
What have I done?
So I followed the Beginner's Guide to aid me in the installation, with some exceptions:
* I used Linux Mint 14 to use GParted. The reason I used it is because rEFIt won't sync the GPT and MBR tables properly when I try and use `mkfs.ext4 /dev/sdaX` inside the Archiso. With Archiso, the filesystem types are considered to be "Unknown" (#wtf no. 1), whereas with Mint that doesn't happen.
This issue is a limitation of the "gptsync" program that's included with rEFIt, not with rEFIt itself. It's also not caused by mkfs; gptsync doesn't even look inside the partitions, AFAIK. Instead, it looks at partition type codes. It understands just a few of them, including the one that all but the very latest versions of libparted use on Linux filesystem partitions. The trouble is that the libparted developers long ago "borrowed" that code from Windows, but they shouldn't have done so. That's being corrected, and gdisk can use the correct code for Linux ("8300" in gdisk). In the future, libparted will use this code, too; the support is already present but isn't yet widely distributed. You could have set the type code to "0700" in gdisk from Arch and gptsync would have worked.
You may be interested to know that gdisk can do the same job that gptsync does, and gdisk can do so much more flexibly. You can read more in the gdisk hybrid MBR documentation. Be aware that hybrid MBRs (which is what gptsync creates) are ugly and dangerous hacks. Sadly, they're necessary to dual-boot Windows and OS X on Macs, but you may be able to dual-boot OS X and Linux without a hybrid MBR. The trick here is to install an EFI boot loader for Linux rather than a BIOS boot loader for Linux. Macs use EFI natively, so this is the superior way to get started, at least theoretically.
The Arch wiki has a number of pages on EFI issues, such as:
https://wiki.archlinux.org/index.php/Un … _Interface
https://wiki.archlinux.org/index.php/UEFI_Bootloaders
https://wiki.archlinux.org/index.php/GRUB_EFI_Examples
The main problem with booting a Mac in EFI mode is that some systems won't activate all their hardware in this way, so with some models you can end up with a network adapter or video display or sound that doesn't work. Other models are fine, though; you'll just have to give it a try and see if it works.
Personally, I think the best way to do it is to use the kernel's EFI stub loader in conjunction with an EFI boot manager like rEFInd or gummiboot. Both are available as Arch packages, but it's better to install from OS X, and that process is much better documented for rEFInd than for gummiboot (although you could adapt the rEFInd documentation for gummiboot, if you liked). rEFIt can work, too, but only if the kernel includes built-in command-line options and is renamed with a ".efi" extension. These are awkward requirements, and since rEFInd is a continuation of rEFIt development, there's not much point in trying to get rEFIt to do the job.

Dual booting in Windows and Linux, but only Linux has calendar, TB 31.0

I'm dual booting using Linux Mint and Windows 7. I have TB 31.0 installed in each OS. TB in Linux has calendar capability; in Windows, there's nothing (by nothing, I mean no calendars - I can't see their properties, for instance, nor access them in any way).
I should add that both Windows and Linux TB programs are sharing the same profile folder (located on a separate partition), hence, all the same add-ons, passwords, etc.
The error console logs the following:
Timestamp: 14/08/2014 6:41:33 PM
Error: Components.classes[cid] is undefined
Source File: resource://calendar/modules/calUtils.jsm -> file:///P:/PortableApps/ThunderbirdPortable/Data/profile/extensions/%7Be2fda1a4-762b-4020-b5ad-a41df1933103%7D/calendar-js/calUtils.js
Line: 17
There are a variety of flow on errors, related to this.
My apologies for posting this in this way; I had intended to submit this via the crashreporter, but I'm having trouble getting the program to crash with this error just now.

A reply to my own question: it turns out that while sharing a profile works pretty well for most purposes, with Lightning it does not, as the extension has different Linux and Windows versions. The problem is solved quite simply: by not using the same profile for each version.
Glad to see that no one wasted time on this one (except me, of course).

Flash 9 destroys dual boot capability

I use a dual-boot computer, with one partition for Linux (Debian) and one for Windows XP. I can't use Flash on Linux as Adobe has never ported it to that platform. So I put my Flash on the Windows partition. Unfortunately, while I have no trouble with Flash 8 on the Windows partition, when I attempt to open Flash 9 on it it crashes the entire system.
My husband found an article in the Winter 2009-2010 issue of 2600, the Hacker Quarterly magazine; it seems that in CS3, which Flash 9 is part of, Adobe has written its copy protection code in such a way as to cause a dual-boot machine to become unbootable after one uses Adobe software. I don't understand all the technical issues, but as the article states, "even though you have paid Adobe real money for their software, they will still potentially ruin your dual-boot system."
I realize Adobe doesn't consider Linux users numerous enough to accommodate, but by taking my money for their product, the company has an obligation to give me value in return. The value I expect is to be able to use the software I paid for - it's not up to Adobe to decide which OS I should use. At least they could warn people that you can't use CS3 (and probably not CS4) on a dual-boot system. I will now start learning to use Inkscape immediately.

I would get another harddrive and put Linux on one and windows on the other then get a hardware switch to switch between them it's much more stable.

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.
