Hi all,
I'm a recent lilo convert, so I'm rather new to grub.
Summary
=======
I recently had to reinstall MS Windows XP (sigh), and I'm now having trouble
getting grub to boot it. Debian boots OK. When booting XP, I see:
Disk error
Press any key to restart
Missing operating system
The System
==========
BIOS is set to boot off the PATA drive. The drives on the system are:
hda PATA: (all ext3)
Various backup partitions. Expendable. Contains the system's MBR.
hde SATA: MS Windows XP (all FAT32)
hde1 (hd1,0) MS Windows OS (bootable)
hde2 (hd1,1) D drive
hde3 (hd1,2) E drive
hdg SATA: GNU/Linux (all ext3)
hdg1 (hd2,0) /boot
hdg2 (hd2,1) /var
hdg3 (hd2,2) swap
hdg5 (hd2,4) /home
hdg6 (hd2,5) /
hdg7 (hd2,6) /usr/local
Grub Configuration
==================
Grub was installed on /dev/hda. My grub menu looks like this:
title Debian GNU/Linux, kernel 2.6.10
root (hd2,0)
kernel /vmlinuz-2.6.10 root=/dev/hdg6 ro
savedefault
boot
title Windows NT/2000/XP
map (hd0) (hd1)
map (hd1) (hd0)
rootnoverify (hd1,0)
savedefault
makeactive
chainloader +1
What I tried
============
When I installed XP, I removed the PATA drive so XP thought it was
installing itself onto the "first drive".
After finding that XP wouldn't boot, I tried:
1. disconnect the PATA drive
2. run the Windows XP recovery console
3. use "fixmbr" and "fixboot".
4. reconnect the PATA drive
But it didn't work. I'm a little reluctant to repeat the above procedure
without taking the PATA drive out because I don't want to lose the ability
to boot into Debian. I'm also very unknowledgable with Microsoft's
operating systems.
I don't understand why this isn't working:
* BIOS boots of the PATA drive.
* Grub is installed in the MBR on the PATA drive.
* Windows first bootloader is on the MBR of (hd1)
* I'm not sure how Windows boots after that, but I assume this is where
the problem is. What exactly happens once the MS first bootloader
is loaded?
Any ideas? I'm on unfamiliar ground all around. Should I try running
fixboot with the PATA drive still connected?
Thanks!
Pete
