My Macbook Pro HD is divided in 3 partitions of equal size. The first one has Snow Leopard installed on it, the second one has Windows 7 on it, and the third one is used to store backups (Clonezilla disk images) of the first two partitions.
Note: I did not use bootcamp. I just installed Windows from the setup dvd and installed the bootcamp drivers afterwards.
This worked very well until I restored my Mac disk image. Snow Leopard runs fine, but when I can't boot Windows anymore. If I press the ALT key during startup the system only shows the icon for the Mac partition.
Disk utility shows the Windows partition as "disk0s3" and in gray. The "verify disk" button outputs "Invalid B-tree node size."
Any ideas on how to fix this?
