    you can use the fdisk command..... in dos. But this some times does not work. If it does not work reinstall Fc4 with minimal packages and unmount the mbr.

    try this tooo......

    check this link :

    http://ilab.usc.edu/rjpeters/faq.html

    DOS-based solution :

    Boot with a DOS floppy that has "debug" on it; run "debug". At the '-' prompt, "block-fill" a 512-byte chunk of memory with zeroes:

    f 9000:0 200 0

    Start assembly mode with the 'a' command, and enter the following code:

    mov dx,9000
    mov es,dx
    xor bx,bx
    mov cx,0001
    mov dx,0080
    mov ax,0301
    int 13
    int 20

    Press <Enter> to exit assembly mode, take a deep breath - and press "g" to execute, then "q" to quit "debug". Your HD is now in a virgin state, and ready for partitioning and installation.
    { got these details from rcgreen's reply }

    Hi,ambar.

    I have had success with GParted. Once I had a disk on which I had written "zeroes" with a vendor test program (to clean everything off) was to write a new "label" with GParted. It's small, so it boots up from the CD quickly, has a GUI, can manipulate partitions, etc.

    As with any powerful tool, you can a lot of damage if you are not concentrating on what you are doing ... cheers, drl

    Are you running just one OS exclusively on your hard drive? Just want to verify it's just one.

    fixmbr may do the trick for you. If you get really desperate you could install a boot loader to your mbr and setup the wait time to 1.

    FYI FC isn't known to be the most stable. If you want RH I would try CentOS (RedHat but with proprietary stuff removed). Not sure if CentOS would have the same incompatibilities you've experienced though. FC users are beta testers for RH it seems.
