Bootcamp with Windows XP not working after Yosemite

Question

Hello, I&#x27;m in the same boat as many others. I have Yosemite and Windows XP on two separate partitions but now I cannot get Windows to boot, either from the restart option or holding alt at startup. I am able to see the partition and access the files there from the OS X side.Last login: Mon Nov  9 09:06:40 on ttys001kit-lambs-mac-pro:~ kitlamb$ diskutil list/dev/disk0   #:                       TYPE NAME                    SIZE       IDENTIFIER   0:      GUID_partition_scheme                        *640.1 GB   disk0   1:                        EFI EFI                     209.7 MB   disk0s1   2:                  Apple_HFS Macintosh HD            477.2 GB   disk0s2   3:                 Apple_Boot Recovery HD             650.0 MB   disk0s3   4:       Microsoft Basic Data BOOTCAMP                162.1 GB   disk0s4/dev/disk1   #:                       TYPE NAME                    SIZE       IDENTIFIER   0:     FDisk_partition_scheme                        *1.0 TB     disk1   1:                 DOS_FAT_32 FATPASS                 1.0 TB     disk1s1kit-lambs-mac-pro:~ kitlamb$ diskutil cs listNo CoreStorage logical volume groups foundkit-lambs-mac-pro:~ kitlamb$ sudo gpt -vv -r show /dev/disk0Password:gpt show: /dev/disk0: mediasize&#x3D;640135028736;

1. Do you have any third-party NTFS software?2. What year/model is your Mac?3. What events took place before Windows stopped working?4. Was there any resizing/repartitioning activity on the disk?

kwlambo · Answer

I do not have any third-party NTFS software. I have a MacPro4,1 from 2009. I stopped being able to boot to Windows after I updated to Yosemite. There was not any resizing on the partitions.

Can you see Windows in System Preferences -&gt; Startup Disks? If you do, can you select and try to boot from it?If it fails, try Resetting the System Management Controller (SMC) on your Mac - Apple Support and How to Reset NVRAM on your Mac - Apple Support and try the Startup Disk method again.

kwlambo · Answer

In the Startup Disks menu there is an option for &#x27;BOOTCAMP Windows&#x27; but the icon, which used to be a hard drive, is now a Dropbox folder icon. If I try to restart from there it says "You can&#x27;t change the startup disk to the selected disk: the bless tool was unable to set the current boot disk."

I will give those recommendations a shot. Thank you.

The Bless error is strange, if you are on Yosemite. Can you check Applications -&gt; Utilities -&gt; Console logs for any error messages to disks or boot camp?

Did Windows XP shutdown normally the last time it was working?Also, do you have a spare SATA drive that can be used to install a copy of OS X?Did you upgrade from Snow Leopard?
