Badly boot camped disaster
I have to reset someones iMac but I have been bumping into some problems.
It was badly Boot Camped by a friends son back in 2011.
So badly that he didn't even install the support software.
Running Windows 7 32 Bit Ultimate which is functional but the issue is that the Mac partition has kind of vanished.
Alt at start up brings up EFI, Windows and Recovery options but when I try to use disk utility to try some repairs/wipes the Mac partition is showing but grayed out.
Verify says the partition needs to be repaired but the repair always fails and attempts to erase the HDD fail due to it being unable to unmount the partitions.
Any clue as to why this happened and hopefully a suggestion about how on earth I can fix this mess?
iMac, Windows 7
