I just installed Windows 7 onto a new 60gb partition on my HDD alongside Vista, which is occupying the rest of the HDD. Windows Disk Management now won't let me format the Vista partition although I no longer require it. How can I format that space to use as storage?
Sorry I mustn't have been clear enough. I created a new blank partition on the HDD, I then installed Windows 7 to it, thus having Vista and 7 on the same HDD but separate partitions. I then made the Windows 7 partition "active" through a context menu in Disk Management, now I can't boot.
