[QUOTE="quintin1992, post: 816556, member: 28868"] I've searched for this problem on other places, but haven't found anything that was the same as my case. I recently repaired my disk with disk utility, and got back 40 gigs that had gone missing (sister turned off comp while i was partitioning, 40 gigs went and didnt come back). When I tried to then use Boot Camp to partition Windows, it said, "Your startup disk cannot be partitioned or restored to a single partition. Back up your startup disk and use Disk Utility to format your startup disk as a single Mac OS Extendted (Journaled) volume. Restore your information to the startup disk and try using Boot Camp assistant again." However, when i looked at my disk, it was alread set as Mac OS Extendted (Journaled) volume. So im kinda clueless. When i was searching for this though, there was something similar where people had upgraded their memory size (i.e. 120g to 250g) and had the same problem. They were told it was because their disk was formatted as APM, not GUID. I however have used Boot Camp before to make a Windows Partition (which i deleted due to a system32 error). So unless when i repaired my disk it reformatted to APM, i don't know what the problem is. [/QUOTE]
