Windows 7 partition got corrupted after yosemite upgrade

Loner T please help. I can't believe Apple would do this to me. After Yosemite upgrade, windows 7 keeps booting into setup or recovery.

The recovery tool or bootrec is not able to find any valid windows partition.

I just noticed that there is a partition 5. I never created a 100GB partition.

Surprisingly OS X does mount Windows 7 disk. I can click on some files and but others error out.

Its a two fold problem: First one as I stated above that windows recovery tool is not able to find any valid partitions. The other problem is that Yosemite upgrade took the windows partition and split into two.

No. I didn't create any additional partitions from within Windows. I am convinced that its Yosemite that messed it up. From within OS X's mounted Windows partition, I can access my relatively older created files without any problems. When I try to access some of the newly created files, they error out. I suspect that those files are residing on the 100GB partition.

This is a question for Winclone folks. During Restore, if you restore from a 'shrunk' image and restore it to a larger partition, the restore is first done to the same shrunk size, then it is expanded to the designated size, by manipulating the NTFS header and 'moving' it to the larger partition boundary. A chkdsk is then executed so that the MFT and NTFS occupies the entire designated partition. If the 'old' and 'shrunk' NTFS header and MFT is left intact in the original location, Yosemite will see two live headers, and create two parts.


If you had the pre-restore size as 100GB and the expanded size was 400GB (rdisk0s4), Yosemite did the 'correct' procedure by creating the original 100GB and 300GB (perhaps a better option was for the Yosemite upgrade to fail), but the 100GB header (rdisk0s5) is no longer valid because it is no longer linked in the MFT, as it points to a non-existent location on disk.


1. Do you have the original Winclone image?

2. Were any files modified after the expanded Windows was in place (very likely because that was the intent)?

3. The files may get corrupted (as you have observed) because the 100G and 300G chunks now have independent MFTs.
