GRUB Repairing help

[vengeance]

Well,hi to every1 on the forums did a partition on bro's hd a few days ago and it seemingly screwed my GRUB up (some mbr issues ).PC wasn't booting so got windows up by using fixmbr from the windows XP installation cd
Just want to get grub back up now so inserted my opensuse 10.2 installation dvd ,selected to repair a previous installation ,went upto to the final step of fixing the boot loader.
The repair box showed me the existing versions of grub ,from googling i found we need to edit the grub configuration file to get it back running,but from the repair dialog just couldn't find it
it shows the device.map file and its contents and gives me these errors when finish selecting some configuration

Error 21:Selected disk drives does not exist
grub ->setup --stage2=/boot/grub/stage2 (hd0) (hd 1,0)

Error 21:Selected disk drives does not exist
grub >quit

Can someone help please its driving me nuts

Hi and Welcome !

Partition Structure has been changed and you have to edit conf files to point to correct partitions.

Boot up from any LiveCD, mount SuSe partition and post the contents of /boot/grub/menu.lst and /etc/fstab files. Post the output of fdisk -l command too.

/dev/sda7            /data6               ext3       defaults              1 1

the problem with /boot/grub/menu.lst is that it doesn't have permission to access by any other user except root.i used ubuntu live cd to access it.in my suse dvd there's an option for rescue system should i use it to change permission on the file and then use ubuntu live cd to get its contents. what would be the command like?

[devils casper]

You can gain root privileges using sudo.
Execute this

sudo less <path_of_menu.lst_file>

above command will prompt for password, hit Enter key.

Edit /etc/fstab file. Contents should be

will try that 1
btw can i use the supergrub cd just in case this doesn't work coz i found a similar solution suggested by u on the tuxforums ?

[devils casper]

SuperGRUB is for re-installing GRUB only. If conf files are not correct, SuperGRUB will not work.
