My son was using Windows 7 on his computer and decided he wanted to dual boot with Ubuntu. He attempted to shrink the partition but could not, so he downloaded another program to shrink but I think he messed up and lost the OS.
So to rectify I told him to install Ubuntu but he wants to dual boot as he is a gamer.
I put Windows installation disk back in but it said NTFS files missing message.
So downloaded GParted but his drives are locked, I tried to format to NTFS in the disk utility which seemed to work, but now when we put the Windows disk in for booting we are getting a black screen with a flashing cursor.
We are really stuck as to what to do now, it may be down to the fact that the partitions are locked. I know the OS has to be locked but can't unlock the other partition.
Would installing Linux mint rectify this problem?
