    Is there any reason for setting Windows Harddisk as IDE-0?
    Before the Linux drive died, IDE-0 WAS the 1st boot device. Grub is probably on IDE-0 (the Windows drive) already or else I would not get the "GRUB" line as the BIOS boot output. (See post #6).
    I understand your reasons for not using IDE-0, but I would like it back this way.

    Thats why I suggested you to keep current settings. If you install GRUB in MBR of Windows Harddisk again, you might face same problem again.

    If you want to install GRUB in Windows Harddisk only, you have to edit grub.conf, /etc/fstab files and re-install GRUB.

    Post the contents of /etc/fstab file here.
    It is amazing what you can accomplish if you do not care who gets the credit.

    Why must I re-install GRUB on the Windows drive...its already there, isn't it? This is a grub.conf problem or a device.map problem. isn't it?
    When the boot messages are output there are two lines:
    "GRUB Loading stage1.5"
    "GRUB Loading Please wait..."
    Then the GRUB menu comes up.

    Here is the fstab file
    /dev/VolGroup00/LogVol00 / ext3 defaults 1 1
    LABEL=/boot /boot ext3 defaults 1 2
    tmpfs /dev/shm tmpfs defaults 0 0
    devpts /dev/pts devpts gid=5,mode=620 0 0
    sysfs /sys sysfs defaults 0 0
    proc /proc proc defaults 0 0
    /dev/VolGroup00/LogVol01 swap swap defaults 0 0
    ---
    device.map:
    (hd0) /dev/hda
    (hd1) /dev/hdd
    ----
    grub.conf:
    # grub.conf generated by anaconda
    #
    default=0
    timeout=20
    splashimage=(hd0,0)/grub/splash.xpm.gz
    #hiddenmenu
    title Windows 2000 Pro SP3 on primary drive
    map (hd0) (hd1)
    map (hd1) (hd0)
    rootnoverify (hd1,0)
    chainloader +1
    title CentOS (2.6.18-164.6.1.el5)
    root (hd0,0)
    kernel /vmlinuz-2.6.18-164.6.1.el5 ro root=/dev/VolGroup00/LogVol00 rhgb quiet
    initrd /initrd-2.6.18-164.6.1.el5.img

    Its interesting, if I go to the BIOS and mark IDE-0 as Not Installed, I can still boot into Linux.

    But before the drive crashed, I could not mark IDE-1 as Not Installed and boot successfully.
    Perhaps you are correct, Devil's Casper. Perhaps it IS best to leave this way. If the Windows drive dies, then I can still boot Linux.

    I accept your suggestion. I still can't help wondering what is in the MBR of the Windows drive.

    Thank you for your help.
