I know there are several posts on this already, but I am unable to figure out how to fix my boot loader by reading the forums. I have tried both GRUB and GRUB2 and have been unable to successfully boot Windows XP. The file system is still there but when I try to load Windows from GRUB I just get a blank screen and then GRUB reboots... Any idea's on what I can do?

Edit:

I tried super GRUB2 however only linux kernels were listed...

I tried with Super Grub and still not dice...

Edit:

I ran the bash script as @wojox suggested. Results show core. Img is missing? :

Do you remember where you installed grub? Specifically, was it to the MBR or to the Ubuntu partition? Super Grub is a fantastic piece of software that will boot almost anything and help you fix broken boot loaders . –  boehj Apr 26 '11 at 17:30
    
I do not.. Sorry I am a bit of a newb :S I will give Super Grub a try –  Richard Apr 26 '11 at 17:34
    
OK, no problem. Get the Super Grub disk .iso and burn it. The language is, unfortunately, a bit 'out there' (I think the main developer is Spanish) but you should be able to find the option to boot Windows using Super Grub. I wouldn't try to fix the boot loader just yet. –  boehj Apr 26 '11 at 17:47
    
I'll need to pass this one onto more capable hands. I've never come across a situation where Super Grub can't boot an OS. There's another option available to you that involves using your Windows installation CD to repair the boot loader. This will nuke grub but that's easily reinstalled afterwards. I don't have much experience in this area but I'm sure someone on here could help you through the process. –  boehj Apr 26 '11 at 18:14
    
@boehj, Thanks for you help. I will try to located a find a windows disk –  Richard Apr 26 '11 at 18:18

You booted into Ubuntu and ran

sudo update-grub

Try running a live cd and download and run BootInfoScript

I ran the script as suggested... Looks like grub can't find core.img? –  Richard Apr 26 '11 at 18:55
    
Run from a live CD: sudo apt-get install testdisk Then sudo testdisk –  wojox Apr 26 '11 at 21:18

I believe the issue I was having is that I had grub installed in the begging of my windows partition as well of my main drive? Also I have GRUB 1 and 2 installed which from my understanding of grub, I do not believe is a good idea. I followed the instructions from this forum to uninstall grub and GRUB2 and reinstall a fresh GRUB2. Problem I had next was that Windows would not boot... I would just get a blinking cursor. I used the Windows cd to boot into console and used the FIXBOOT command. I anticipated that this would wipe out GRUB, but it left GRUB intact and now I can boot both Windows and Lubuntu.

If you used GParted to partition the disk, the Windows system will have an error that needs chkdsk to repair. I did this with an XP disk. It doesn't matter what disk. I have Home Edition on my netbook and used an XP Pro disk to run a command prompt. At the prompt, type chkdsk c: /f /r. The options will locate bad sectors and repair them.
