My computer is an old AST Bravo MS-5166. Today I did something stupid. I went crazy with Fdisk and ruined my memory, and now Red Hat 6.2 won't boot up properly. Basically it tries to boot up and then halts on the line "Kernel panic: VFS: Unable to mount root fs on 03:05". What I was trying to do was format my computer so I could reinstall Linux and start over fresh. Now I can't format at all, as I have no prompt to work with. The computer executes all of this and doesn't do anything with the boot disk when I turn the computer on with it in. My BIOS don't have any options to allow formatting. What can I possibly do to be able to use my computer again?
