problem on reinstalling windows over linux

[freenhigh]

i had rhel5 server on my machine and then i reinstalled my windows XP later. Now i don't see the grub screen to choose between XP and Linux.

then i booted my computer through rhel5 DVD and started it on linux rescue mode.

it gives an error as "you don't have any linux partitions.

then i tried to mount my partitions manually.

sh-3.1# df -h
/dev /dev
/tmp/loop0 /mnt/runtime

sh-3.1# fdisk -l

/dev/sda1 HPFS/NTFS
/dev/sda2 W95 Ext'd (LBA)
/dev/sda3 HPFS/NTFS
/dev/sda5 Linux (/boot)
/dev/sda6 Linux (/)
/dev/sda7 Linux (/var1)
/dev/sda8 Linux (/backup)
/dev/sda9 Linux Swap / Solaris
/dev/sda10 Linux (/home)
/dev/sda11 W95 FAT32

even in mnt directory i don't find sysimage directory so i made one and mounted my partitions in it

sh-3.1# mount /dev/sda6 /mnt/sysimage
sh-3.1# mount /dev/sda5 /mnt/sysimage/boot
sh-3.1# mount /dev/sda7 /mnt/sysimage/var
sh-3.1# mount /dev/sda8 /mnt/sysimage/backup
sh-3.1# mount /dev/sda10 /mnt/sysimage/home

now it shows whole mounted disks while df -h

now i chrooted

sh-3.1# chroot /mnt/sysimage

sh-3.1# /sbin/grub-install /dev/sda

It gives an error the sda is not a block device

Please help me out

you chrooted to /mnt/sysimage, so you are trying to install your grub image to /mnt/sysimage/dev/sda

obviously this won't work as is. you have to mount your device directory into your chrooted environment.

mount -o bind /dev /mnt/sysimage/dev

THEN chroot, then grub-install

i have done as u said but still it gives an error on installing the grub

" The file /boot/grub/stage1 not read correctly. "

Boot into any linux live CD.

Here UBUNTU Live CD used. This can be the live installer cd or the older live session Ubuntu cds.

When you get to the desktop open a terminal and enter. (I am going to give you the commands and then I will explain them later)

Code:

sudo grub

This will get you a “grub>” prompt (i.e. the grub shell). At grub>. enter these commands

Code:

find /boot/grub/stage1

This will return a location. If you have more than one, select the installation that you want to provide the grub files.
Next, THIS IS IMPORTANT, whatever was returned for the find command use it in the next line (you are still at grub>.
when you enter the next 3 commands)

Code:

root (hd?,?)

Again use the value from the find command i.e. if find returned (hd0,1) then you would enter root (hd0,1)

Next enter the command to install grub to the mbr

Code:

setup (hd0)

Finally exit the grub shell
Code:

quit

That is it. Grub will be installed to the mbr.
When you reboot, you will have the grub menu at startup.


let me know if its not work.
