Recently I did a very bad install with Redhat Linux 7.1, and I decided I don't need it anymore so I just want it off my drive. However, I tried using FDISK and it won't delete the extended partition its on because it says there are logical dos drives. However, when I go and try to delete the logical dos drives it says they are all deleted. Then when I go back to the extended partition, it still won't delete it. Help!
