Killed 11.3 and XP dual boot

OpenSUSE 11.3 and Windows XP are on the same hard drive with a dual boot option from GRUB. More space was needed for XP, so I resized partitions to create more room for XP using PartedMagic. I moved free space at the end of home (sda7) into the XP’s C: (sda2). I’ve done this before (less space for XP and more for 11.3) without a problem but made a mess of it this time.

When done, the computer would hang with a blank screen after giving the options for CMOS. Eventually I was able to get WinXP to boot into the new, larger partition but have completely lost the ability to dual boot.

Using a LiveDVD, I can mount the three oS 11.3 partitions with swap (sda5), root (sda6), and home (sda7). Each is there in it’s modified form and/or new location on the drive and I can access files in sda7.

I’ve found HowTos for creating a dual boot system but nothing that helps with recovering from my mistake.

How do I get back the dual boot option from GRUB?

Would an “upgrade” or “new” installation of oS 11.3 work? Something else?

TIA,
Mark Z.

The solution was to reinstall GRUB. It took a while to figure out because I didn’t know what to ask.

Here’s where I found the answer: [HowTo Boot into openSUSE when it won’t Boot from the Grub Code on the Hard Drive](http://opensus.swerdna.org/susebootfive.html#broken grub)

Another problem was not knowing that the login for the Rescue System is “root”.
