I booted up using the livecd and tried to get to the terminal but
failed. The live desktop session never got loaded (remember it's an old
pc with Celeron 256 Mb RAM), so I went <alt> + <F1-F6> but it gives an
error ("...unable to read data cache...", "...unable to read page...",
etc.)

So then I booted up using the Alternate cd but I could only get to a
Busybox or something, and when I typed "sudo fdisk -l" it complains
because saying it doesn't recognize that command.

What should I do then?
