duel boot problem
 

windows wasn't working so i reinstalled it and now i cant get to red hat linux . how do i get the back to the boot to pick what operation system to log onto

Windows has overwritten your MBR.

To reinstall Grub on the MBR:
1) Insert RedHat CD1 and reboot
2) At the "boot:" prompt type "linux rescue"
3) At the prompt change you system root "chroot /mnt/sysimage"
4) Install Grub "/sbin/grub-install /dev/hda"

Use a live cd to boot. Then chroot to get to your linux system. (If your system is on hda2 then you would chroot /dev/hda2.) You don't need X. Then from a root login rerun lilo. W/ grub I would think you would have to do the same. But just reistall grub to the MBR.
Hope this helps!
