I have 3 HDDs in my computer. One running Windows XP Pro, one storing all of my data, and one running RH Linux. I had GRUB installed, and it would boot to either Windows or Linux. Well, Windows decided to screw up on me, and I reinstalled. Because of that, it "fixed" my mbr, and now GRUB does not come up, and I cannot get to Linux. I had a boot disk made during isntallation of Linux, but the disk is now corrupt. I was wondering is there was any way to create a boot disk that will boot to my linux installation or something.

-------------------------------------------------------------------

You can create a boot disk from rawrite utility which is on the linux cd in the dosutils directory you can run it in the windows it will ask the image file give the path for the image directory & than put the floppy

-------------------------------------------------------------------

Alternatively you should be able to boot a pre-installed system when booting from the installation CD. There may also be a rescue option too.

-------------------------------------------------------------------

Follow these steps to get your grub back...:
1) Use the installation disk to boot....
2) while at the selection prompt type "linux rescue" (without quotes)...
then select the options as needed..
3) after your previously installed linux is mounted in /mnt/sysimage,
4) on the prompt type chroot /mnt/sysimage , 5) then type grub at the prompt then press enter. you will get a grub prompt, now
6) type "find /boot/grub/sysimage1" then press enter,
7) now whichever disk information you get eg: (hda0,2), note it down...
8) now type "root ("the disk information you got")" eg: grub>root (hda0,2)
9) now type "setup (hda0)" (use this according to the drive information you got)
then press enter.
10).press ctrl-c then exit two times... system will restart and now you can see your grub....

-------------------------------------------------------------------

You can also press F8 during boot up in order to bring up you BOOT MENU (or whatever key your bios is using), and then select which HD you want your computer to boot from. This is how I do it, because I have WinXP Pro on one HD with all of my data and SuSe 9.1 Pro on another hd, and because I do not want to scrue up my whole system I didn't install Grub nor Lilo, and I don't want to mess with boot.ini I found the BOOT MENU to be the best option.

-------------------------------------------------------------------

To correct myself in the step no. 6. it is /boot/grub/stage1
installing a bootloader is the best option for a muliboot system is concerned as it is installed only once and not all systems give boot menu by pressing F8.
