Q: Updated to Yosemite and Bootcamp XP stopped working

Hello. Thank you ahead for any help anyone can provide.

 

I've read several threads on this but am not sure they apply to my problem. I have a spring 2011 iMac 27". Run Windows XP via bootcamp. I do have 3 partitions show up when I access the boot selector on startup. Mac HD, Bootcamp, Recovery. When I select Bootcamp, Windows starts to load, gets 2 bars, then crashes to blue screen and the computer immediately restarts.

 

I ran testdisk and the partition start/end points seem to be correct. (no gaps or over lap). At this point I'm not really sure what to do. :/

    The version that you are referring to is the Bootcamp Assistant version, not the BC Drivers that are installed on the WXP side. WXP is self-contained once fully installed. Drivers can be updated by Windows Update or manually when booted in XP.

     

    I recommend installing the version of OSX (SL) on a USB (or external disk) and trying to bring up Windows.

     

    If your Mac has Thunderbolt  ports, a new set of devices are added. Such devices can cause problem.

    Hmmm ok. Do you know anyone who's gotten Windows XP to work after upgrading to Yosemite? Is a fix possible? Or should I erase my Boocamp partition and install a newer version of Windows?

     

    My Mac doesn't have thunderbolt, it has Firewire 800.

     

    Ill try installing OS SL to an external device. Once that's done, what do I do?

    Can you try the older version of OSX and try before you delete XP?

    Ill need to figure out how to install OS 10.6 from DVD to external drive. Once I do that what do I do? Run OS SL then try to restart to Windows?

    Ok I installed snow leopard onto an external drive. Started the mac in snow leopard and then restarted to bootcamp, Windows still crashed. Is there something I should be doing to try to fix this?

    Hello. I'm considering trying the fixboot, fixmbr, bootcfg commands from the Windows XP recovery console. Not really sure what to attempt at this point. Any help is appreciated.

    Try the /ScanOS first. /FixBoot, /FixMBR and BCD rebuild in that order.

    Should I be worried about any of these affecting my Mac partition? Also Windows XP doesn't have ScanOS, just bootcfg.

    None of these commands should affect your OS X side, but a good backup is always recommended.

    Ok, I did bootcfg /list and it said "there are currently no boot entries available to display".

     

    Bootcfg /scan does list my Windows XP install.

     

    So now I believe this means I have to do a bootcfg /rebuild?

    Yes, you need to rebuild. ScanOS and scan behave similarly.

    OMG It worked! 88 miles per hour!!!! My Windows XP is loading wohoo!

     

    So now when I select Windows on the boot selecter at startup, it goes to the boot.ini list giving me 2 optios:

    Windows XP Home Edition (which is what I named it using bootcfg /rebuild) &

    Windows XP Home Edition (which is the old one and still crashes)

     

    I opened the boot.ini file in notepad to delete the 2nd (original option) that doesn't work and heres what the boot.ini file reads:

     

    [boot loader]

    timeout=20

    default=multi(0)disk(0)rdisk(0)partition(4)\WINDOWS

    [operating systems]

    multi(0)disk(0)rdisk(0)partition(4)\WINDOWS="Windows XP Home Edition" /fastdetect

    multi(0)disk(0)rdisk(0)partition(3)\WINDOWS="Windows XP Home Edition" /fastdetect

     

    The partitian numbers are different. The top is the one that works, and the bottom doesn't work.

     

     

    Thank you for the help Loner T!

    There is a reason for the entry which does not work. It is fixable too. If you notice the difference is because your original XP installation came from a Snow Leopard OS X machine, which has no concept of a Recovery HD. On post-SL OS X versions, Recovery HD was introduced, which pushed Bootcamp to disk0s4 (instead of disk0s3). My recommendation is to delete the following entry and test again. This is to ensure that future recovery of XP can be done without confusing the Windows Recovery process.

    multi(0)disk(0)rdisk(0)partition(3)\WINDOWS="Windows XP Home Edition" /fastdetect

    I also would recommend a fresh backup of XP on an external drive to be used as a baseline for the future.

     

    Glad to see it work properly.

    I just erased the faulty boot reference line and all is good now. It actually seems like it loads faster than before all of this.

     

    Hopefully someone at Apple will see this and incorporate this fix into their OS update...update. This is a fairly simple and obvious glitch in the Yosemite upgrade that could be easily fixed.

    The XP support on Snow Leopard (10.6.x) being carried over to Yosemite (10.10.x) is highly unlikely.
