I had installed Ubuntu 8.10 on my External Drive, on a partition, so I would not risk messing up my Windows Installation, and to keep my comptuer booting windows all the time when my External was not plugged in.

Started out by de-fragmenting and repairing any bad sectors on my computers hard drive. Originally I tried to use an Unbuntu 8.10 live disc that I got from a magazine, however it wouldn't load either as a live disc or full install. It kept giving me the message; Busybox V1.10.2 (unbuntu 1.1:10.2-1unbuntu6) built-in shell (ash) Enter 'help' for a list of built-in commands. (initramfs) I created further live discs for Kunbuntu8:10, Xunbuntu8:10, Xunbuntu8:1 Alternate, the alternate version couldn't find my CD driver and the Kunbuntu8:10 & Xunbuntu8:10 gave the same message as above 'Busybox etc'. At one point I tried the third option on the live disc about 'help to boot on start up' from this point on every time I start up I get the choice of Windows XP Home edition or Unbuntu (only windows works, Unbuntu gives an error message about 'Busybox etc' as above.
