I had 2 hard discs. One 80 GB PATA and a 160 GB SATA. I have Windows XP and Ubuntu-9.4 on my 80 GB hard disc.

install to an external USB hard drive. This person already had Debian Linux installed on their local hard drive and was attempting to do an install of Ubuntu to an external USB hard drive. During the Ubuntu USB http://www.pendrivelinux.com/grub-error-21-after-full-install-to-usb-hard-drive/ hard drive installation process, Grub was accidently moved from the internal hard drive to their external hard drive, rendering the original Linux system unbootable without the external drive plugged in. When attempting to boot from the original Debian Linux system, they would encounter the Grub Error 21 shortly after the Grub 1.5 boot process. The good news is that the fix to repair Grub on the original system was quite simple and is illustrated below: Reinstalling or fixing Grub after error 21: Boot error 21 into the original Linux system with the external hard drive still installed (or you can boot from a Live Ubuntu CD). Open up a terminal and type sudo su Type fdisk -l and locate your Linux boot partition from the list Example: sda1 or hda1 Type grub-install /dev/sdx or grub-install /dev/hdx to reinstall or repair Grub! Reboot and test!
