Rescue disk
Here's how you make it work:
- get the install CDROM.
- at the syslinux prompt, type: linux rescue
- follow through all the prompts, and let it mount the linux partitions.
- at the shell, type: chroot /tmp/syslinux (or whatever the command is, the system will tell you)
- do a df -k to see what device you are using for / (on the dell, it was sda1)
- do a grub-install with the appropriate device name (without the partition number)
