Alright, so I recently wanted to delete my Vista partition, because I dont use it, but when I opened up partition magic, it gave me error 117. So I installed a different program, Acronis Partition Expert, and it said that it cant get exclusive access to my partitions, and pretty much failed to install. Then I downloaded the GParted live CD, and when I looked at my partitions, there was just one big unallocated 180GB thing, no partitions at all.
Yet both XP and Vista work perfectly fine. The only odd thing about my XP is that the drive leter is H instead of C
So please help me out, I dont want to have to reformat my entire pc.
