Hi, Bought my 15" MBP Late 2011 (High-end) last week. I set up Bootcamp with 60gb of space. I read that the simplest way to add space to the Windows partition is by partitioning the main HFS drive and formatting it on Windows itself to NTFS. Boy, was I wrong. After I partitioned my HFS+ drive, the Windows drive went missing during boot up. It showed on Disk Utility as unbootable. Reading that it might be a MBR problem, I ran the Windows repairer and executed /fixmbr and /fixboot. So now it appeared back as a Windows partition but it wouldn't boot, staying forever at the blinking cursor and a black screen when I selected it. Deciding that the best way to solve it was to redo the whole thing, I used Boot Camp Assistant and removed the Windows partition entirely. When I tried to create a new one, it says there are it cannot as some files cannot be moved. I tried to partition my HFS+ drive to force it to move the files but it says "file system cannot be verified". I did a repair of permissions and the disk itself as that was the solution offered by some of the threads here and found some errors. Repaired it in Recovery mode and tried to partition again. This time round the error was "could not unmount disk". What is going on with my HDD? Baffling! Now I am stuck and am not able to bootcamp at all. Thoughts anyone?
