So, I bought a new computer case. I put all of the guts over to the new case, booted it up. Error 22 no such partition.

My situation:

3 Hard Drives.

Drive A - 250gb SATA - Ubuntu + XP dual boot.
Drive B - 250gb SATA - Rsync backup of A.
Drive C - 250gb IDE - Rsync backup of A as well.

I boot up. I get that error. Hmm... I power down, disconnect B and C, boot up... Ubuntu boots fine. K... I power down, hook up the other two drives, boot up with all 3 connected... everything worked.

What exactly happened here to make this happen? Was something written in the boot sector of Drive A after running it solo?
