Question: I'm on a Eee PC and I am running Windows XP and Ubuntu 10.04. I'm starting a big project tomorrow and I wanted to cleanly reinstall both operating systems. After entering the pre-install Windows environement, I let my system run as per usual, however, after I returned to my desk I found a blank screen with `error: no such partition` and a GRUB rescue command prompt. After digging around a bit online I found `ls` which returns `(hd0) (hd0,4) (hd0,3) (hd0,2) (hd0,1)` and `set` which returns `prefix=(hd0,5)/boot/grub && root=hd0,5`

I have Ubuntu on a flash drive, but I can't get that to work because every time I boot up it goes straight to the error screen.

Answer: 
To get it to boot from a cd you may need to change your boot priority in your BIOS settings, these are usually found by pressing Del or F2 on startup.
