I wanted to reformat my SSD so I could install a clean copy of Windows 7 Pro. I tried to reformat, but the Windows installer gave an error along the lines of 'unsupported NTFS format'. I then deleted the partition and then tried to reformat, but Windows won't let me do that either, it says 'Setup was unable to create a new system partition or locate an existing system partition'.
Any ideas on how to fix?
