Testing memory and wiping hard drive before installing Ubuntu

[Ian Bruntlett]

Hi,

I am refurbishing a Toshiba Satellite C50-A-1JM laptop that was donated to
the Computer Wombling Project. This is the approach I usually take:-

1. Test memory with a memtest86+ CD-R
2. Wipe the hard drive with dban CD-R
3. Install Ubuntu or Lubuntu from DVD

Sadly, steps 1 and 2 don't work any more. The system currently has Windows
and Ubuntu on the drive and I am trying to wipe the entire drive to ensure
the donor's privacy.

I can get to a GRUB prompt. Maybe I could type in some kind of GRUB command
to boot from a CD-R - what command(s) would I have to use?

TIA!


Ian
