XP RH9 Grub problem

pagey77 · 09-09-2003, 10:43 AM

Heres the deal:

I had an existing RH9 installation. Installed XP. Grub disappeared. Run RH9 disc1. Linux-rescue. chroot /mnt/sysimage. grub-install /dev/hda1 (a mistake) .Remembered that I should install it on /dev/hda instead. Did it again. Restarted the computer. In Grub lInux is ok, but XP doesnt start up.
I get this message:

Windows XP

rootnoverify (hd0,0)
chainloader +1

GRUB 2 ....something

My grub.conf looks like this:

default=3
timeout=10
splashimage=(hd0,6)/grub/splash.xpm.gz
title Red Hat Linux (2.4.20-19.9)
root (hd0,6)
kernel /vmlinuz-2.4.20-19.9 ro root=LABEL=/ hdd=ide-scsi
initrd /initrd-2.4.20-19.9.img

title Windows XP Professional Edition
rootnoverify (hd0,0)
chainloader +1

What am I doing wrong????

Please help me I really need to get into XP.

Thanks

Where is the winXP partition located ?
The following command displays your partition table.

Code:

fdisk -l

If winXP is on /dev/hda1, you may have corrupted your winXP partition.

pagey77,

Change the default entry to 1. Save and exit the grub.conf file. Reboot. XP should be the default option. Press Enter. You'll get into XP. It should work. ( I'm hoping it will.....)

If I have corrupted it what do I do next?

Since winXP is on /dev/hda1, you may have corrupted your winXP partition.

You can try using the windowsXP CD in order to repair the installation.
If that does not work, you will have to re-install windowsXP.

My errors are displayed like this:

GRUB loading stage 2

GRUB loading please wait ...

Error 18

Then nothing more happens

Quote from the GRUB manual.

Quote:

Error 18 : Selected cylinder exceeds maximum supported by BIOS.

This error is returned when a read is attempted at a linear block address beyond the end of the BIOS translated area. This generally happens if your disk is larger than the BIOS can handle (512MB for (E)IDE disks on older machines or larger than 8GB in general).

First, you installed GRUB on /dev/hda1 (windowsXP),
Then you installed GRUB in the MBR.
When you try using GRUB (MBR) to boot winXP, GRUB ends up booting the GRUB which is on /dev/hda1

The winXP partition is most likely corrupted.

You can try using the windowsXP CD in order to repair the installation.
However this will probably not work.
You will have to re-install windowsXP.

Youre most probably right. The repair didnt work out. It didnt find anything on C but if found all files on D and E. WHat Ive got to do now is to save all my files by mounting my partitions in RH. If oy come up with anything else please let me know.

Thanks
