I recently installed RedHat 5.2 onto my second hard disk.
Unfortunately, I discovered that my old MGA Ultima Video card is not supported, and having no knowledge of Linux as yet, I decided to get rid of it, at least until I have suitable hardware to run X.
I want to reformat this disk to DOS so I can use it again, but DOS's fdisk does not allow me to do this --
it detects that there is several partitions on the disk and won't let me delete the primary partition because of this, but it doesn't recognise these linux partitions in order for me to delete them and then the primary partition. All it can format is the /root partition, which is about 50Mb.
How can I recover my linux disk to DOS format?
