My dual booting system has somehow gotten stomped on. When I try to boot into my XP partition my machine reboots. So I have to rebuild the windows boot sector, wich will probably destroy GRUB. I've looked at some walkthroughs for GRUB but I get confused. I would truly appreciate it if someone could help me with reinstalling GRUB, point me in the right direction for some pretty detailed information on how to do it, or perhaps show me a better solution to my problem (and no a solution would not be just getting rid of Windows, as much as I would love to do that. I need it for a few specialized applications)?

If you followed the recommended install process for suse, your /home and / are on different partitions. If the grub manual is giving you problems, just re-install suse and tell it not to format your /home. Also, when it asks if you want to make a backup disk of the grub install, do so for the future.

Wow, thanks for the quick response! I will try that as soon as I can.

I have been running Windows XP from one IDE hard drive and just installed Suse 10.1 on a SATA hard drive.
Expecting to reload XP as needed in the future and a newbie to Linux, I wanted to make the reloading of an OS to be as painless as possible but could not find information that convinced me that would be possible. I finally came to the conclusion since the XP was already loaded on the IDE HD, I made the SATA HD the BIOS boot preference and let Suse do her install thing.
I did adjust the SATA partitions so data could be stored away from the operating system partitions. Also adjusting the BootLoader during install a little so the SATA HD came first in priority.
Adding some extra software at install messed with my network connection. There was a "DHCP client is already running on et h0" error while trying to test the internet connection. Then I only updated the security critical issues during install.
It worked for a day. Now everything is back to normal. Nothing works like one would expect or hope.
