Hi guys! A few days ago I turned on my MBP and it woulnt start, it just kept for several minutes in a grey screen with the apple logo and a spinning wheel.
I've tried to restore the system but it failed and then I've tried to erase the entire drive. What happens is that I have 2 distinct partions, one for the Mac OS and another one which is a bootcamp partition. The partition for the Mac OS is greyed out and when I select the disk to erase it, it tells me it failed because it couldnt unmount the disk. What can I do to resolve this problem?
Thanks in advance!
