Installed GRUB on 3rd hard drive, how do I boot 1st drive?
I have 3 hard drives with several different partitions.
I have 2 copies of Windows XP Pro, Ubuntu linux, and Fedora Core 2 linux all installed on the first physical hard drive (different partitions obviously)
I have been using Grub to boot between them all but yesterday Windows got messed up and required me to reinstall. After that I was unable to boot Linux so I installed another version of Fedora Core 2 onto my third physical drive.
Now the new install of Fedora (on the third drive) boots but not any of the other versions.
I tried configuring grub.conf to boot the others but I am assuming that it is failing because of grub being installed on my third drive (hdd) but the other OSs are all installed on hda.
I do not have a GRUB boot partition on hda because I was not aware of how much trouble it would save me in the long run.
Here is my grub.conf as well as my hard drive information:

Thanks for any help,
I'm at a lost to explain why XP won't boot - maybe try adding makeactive to each entry.
For the other Fedora, try
Wow, quick reply.
I have worked on this for so long and retyped the entries so many times and Windows never worked but I guess I did something right at one point and never checked again as I pull all my focus on getting Fedora to boot. Windows does boot.
After editing grub.conf with the alterations you suggested it works like a charm. Thanks!
I'm just trying to understand this now... Why would Windows boot but not Linux (well, didn't) when they are both on the same drive? I read the:
Also, Now that I have it all running again, what should I do to be prepared for next time I can't boot (either after reinstalling windows, reinstalling linux, or just boot failure.)? Since I have access to everything right now I would like to be prepared next time. Just the info that I've learned so far will help out allot, but is there a way to make a backup or something?
Thanks again for the quick response! You have no idea how long I tried doing this on my own!
For Linux, you need a boot-loader - all the smarts are in the directory you installed grub to.
Hence the need for the root(hd2,0) directive - this is for grub.
Normally you would have your kernel images in here too, but as you see, you can address it absolutely in need.
Trying to backup the MBR is a mugs game. Seriously not worth trying.
Better option is to re-install if it gets over-written/corrupted.
