    Exclamation NTLDR is missing - Dual Boot separate hard drives

    GRUB seems to have screwed up a bit. I can successfully boot into the distro, however I cannot boot into XP. Whenever I choose the option I get a "NTLDR not found" message. I have 3 hard drives in my system, 1 windows (IDE), 1 linux (IDE), and 1 drive for data (SATA).

    Here is the output from my menu.lst:

    # menu.lst - See: grub(8), info grub, update-grub(8)
    # grub-install(8), grub-floppy(8),
    # grub-md5-crypt, /usr/share/doc/grub
    # and /usr/share/doc/grub-legacy-doc/.

    ## default num
    # Set the default entry to the entry number NUM. Numbering starts from 0, and
    # the entry number 0 is the default if the command is not used.
    #
    # You can specify 'saved' instead of a number. In this case, the default entry
    # is the entry saved with the command 'savedefault'.
    # WARNING: If you are using dmraid do not change this entry to 'saved' or your
    # array will desync and will not let you boot your system.
    default 0

    ## timeout sec

    # (normally the first entry defined).

    Any ideas of whats going wrong? SDB is the Windows drives and SDC is the Linux drive.

    Re: NTLDR is missing - Dual Boot separate hard drives

    its not grub which is the problem. seems your windows is having some prblem. there can be two main reason.

    1. in your boot.ini the hard drive specified is not matching your c:
    solution - change the boot.ini to reflect correctly. I am not MS geek so you will have to do some search for that on the net. should not be a big deal though. some trial and error.
    2. ntldr file is deleted from c:
    solution: copy ntldr from some other comp with same OS version and paste it in your c: drive.

    First try #2 and then see if relsoves the error.

    Re: NTLDR is missing - Dual Boot separate hard drives

    I actually managed to fix this myself with a tip from someone in a Linux chat room (don't remember which).

    I actually commented everything out, so that my GRUB looks like this for the windows entry:

    title Microsoft Windows XP Professional
    rootnoverify (hd1,0)
    # savedefault
    # makeactive
    # map (hd1) (hd0)
    # map (hd0) (hd1)
    chainloader +1
    And windows boots with no issues. Just a tip for those searching in the future!

    hmm... that is interesting... it should work with grub too.. may be the map command are the one creating problem.
