insert linux cd
boot from cd
whwn you get the prompt you will have to write

Alternatively you could do it a safer way.
get dd for windows and copy the bootsector of the linux partition (the first 512 bytes) into a file and call it something memorable like bootsect.dat.
Put that in the root of your c: drive and open up boot.ini and add a line such as this.
C:\BOOTSECT.DAT=”RedHat Linux”
C:\BOOTSECT.DAT=”Mandrake Linux”

Bingo you have your windows loader loading windows and linux, and you didn’t endanger the current running system

I am aware this thread is over 2 years old btw

use ur linux cd & get into rescue mode
then try out these commands :
1. grub-install /dev/hda (or /dev/sda whatever it may be)
2. root (hd0,0) (in the bracket the last zero specifies ur /boot partition number )
3. setup (hd0)

with these steps u are done .

Try reinstalling grub. There should be a command on your install disk/liveCD to do reinstall grub. This will locate *all* your partitions. The microsoft one is bias, and refuses to notice anything nonwindows.
