Hi all,
I virus got my XP installation this morning. I have to install it. When I install windows it will write over the GRUB and I will no longer be able to re-boot my openSusie OS.
My question is After XP is installed is there a way to re-install GRUB without having to re-install openSusie 11.2?
Any help will be appreciated! 
Thank you,
Paul :’(

Yes, boot your PC using the DVD and the repair mode, then select repair
grub, other method if you don’t have the DVD is using the live CD and
select boot installed system, once on openSUSE go to YaST2 and repair
the boot loader

VampirD,
Thank you for your response. I appreciate it and makes sense. 
This is a company laptop. Thank God I had openSusie installed. I was able to xfer all my important files to memory sticks.
The XP install is about done so all I got to do is get the rest of the apps installed.
This is great! I didn’t want to have to reinstall openSusie because I have it just the way I want it and love it. I was able to continue my development on my project today.
Thanks again,
Paul lol!
The actual route to the graphical repair is Not from the ‘Repair Installed System’ option when you first boot the DVD, you actually have to proceed as if for a New Install
All the way to Picture 5 in this:
11.2 Slideshow Images - Windows Live
At pic 5 select repair option
Hi caf4926,
Thanks for the info. I haven’t started the openSusie GRUB repair yet. By the time I installed all the apps needed on the XP OS it was late. I hate all the re-booting every time I install something new. If this was not a company laptop I would have never re-installed XP. My company would frown on that however. :\
I have been working today, but will repair the GRUB as soon as I complete my work today.
This sounds easy and I have the DVD install so this is perfect. I also saved the Grub Menu contents in Kate on a flash drive. So the repair should go very smoothly.
Thank you,
Paul
If you have trouble with the DVD.
Here is another method:
Re-Install Grub Quickly with Parted Magic - openSUSE Forums
I’m having a similar problem with my migration to a new HDD. Windows was installed on the new HDD using the recovery CDs that came with my laptop. I then partitoned the remainder of the hdd up and copied (by cloning each to and image and then restoring) the openSUSE partitions from the old hdd to the new hdd.
So I basically have a booting XP system and and installed but non booting oS system. I now need to get grub re-installed so I get the option to choose os when booting. I tried repair the boot loader by going to the repair installtion on the 11.2 DVD but it is not working. I get an error saying
An error occured during bootlader installation.
Ok, I tried that method and grub now displays on boot but trying to boot oS gives the following error.

Press any key to continue…
Pressing any key just loops back to grub and the same error.
Is the error telling me that initrd does not exist or cannot be found? If so how can I get it back?
You probably have your HD boot order mixed up
Notice the menu from your suse install thinks it’s at root (hd0,2)
So is your suse HD seen as hd0
what is fdisk -l showing

Where is menu.lst placed?
Look at sda3 and sda5 and check for /boot/grub/menu.lst
I don’t use a separate /boot partition, it tends to cause confusion
menu.lst is placed in /dev/sda3/grub/
Running find /boot/grub/menu.lst shows (hd0,2)
I’ve spent so much time on this that I think I’m just going to bite the bullet and re-install oS from scratch.
If I do a clean installtion of oS so it’s dual booting properly, can I then just dd the old hdd partitons over the top leaving the /boot partition alone on the new hdd? I’ll obviously have to change the fstab so it matches the new disk.
Personally I would scrap the /boot
Do some resizing to take up the space it frees up and just have
swap
/
/home
Ok, I’ll try that.
You know you can put the boot flag on the extended and boot from the root partition.
Look at my fdisk:
Device Boot Start End Blocks Id System
/dev/sda1 1 7600 61046968+ 7 HPFS/NTFS

/dev/sda7 19457 30401 87915681 83 Linux
Ok, I finely got it working. It turned out the the symbolic links for vmlinuz and initrd were incorrect. Once I recreated them grub booted oS fine.
Thanks for filling us in:)
