    Master Boot Record (MBR)

    How do you reset the MBR. I have a menu that is comming up for a duel boot but one of the OS's has been removed and I wanted to get rid of that menu, at least for the moment.

    Is there a way to update changes to the MBR?

    if you have lilo, alter /etc/lilo.conf. erase or comment out everything on that os you want to remove. then run lilo without options. if it doesn't give you problems, you're ok.

    fdisk /mbr will rewrite the MBR for you.

    a little dated but,

    I had the same prob once couldent get rid of it (Didnt really know how to but I was formatting again so that sorted it out )
    this is quite leathel but it will work to remove anything off of a disk!!)

    start pc with startup utility disk that has your system files and a copy of debug on it.

    type debug to get the prog going then

    TYPE THIS INTO THE DEBUG PROGRAM EXACTLY


    A 100
    INT 13
    (ENTER)
    RAX
    0301
    RBX
    0200
    F 200 L 200 0
    RCX
    0001
    RDX
    0080 OR 81,82,83
    P
    Q

    That should do it

    Just a side note this looses everything on the HD so format afterwards.

    Cheers
    Q
    And To All Those Opposed, WELL !!!

    If so, you can disable it in the software.
