I have managed to kill Grub by upgrading windows (to windows 7) after installing linux, debian. Now i still had a spare blank partition, so i put on some pc-bsd, thinking it would havbe a decent bootloader (proably grub) but it didn't. so i removed that installed mandriva. Now grub lets me access mandriva, and windows. And i can select debian and see the old grub, but debain doesn't work.

Any tools that I can simple burn to disk that will remove all old boot loaders and create a new one?

btw 64bit processer and OS's.

please be more specific.

"And I can select debian and see the old grub, but debian doesn't work."

What exactly happens when you choose debian and try to boot it?

If you have a digital camera and a small tripod you can use that to capture pics of the various screens as it tries to boot so you don't have to memorize and re-type everything.

Please let us know; this is crucial for helping you.

I've used with success before the Grub Super Disk, which works quite well. It will install Grub for you. Alternately, you can use SysRescCD which I have also used successfully in the past. It has both 32-bit and 64-bit modes, and but usually I end up chrooting into my old system after mounting it up and using that. Just remember to mount the /dev partition into the filesystem first, or grub-install won't be able to find your drives!
