rescue disk

[Eelco]

Hello,

I recently installed edgy eft from the dvd iso.
The live cd wouldn't work so i did a text install.

Everythink seemed to work ok.
After the automatic upgrade i couldn't get in. somehow the bootprocess
stopped and a killalll signal was sent.

So i reinstalled everything. I haven`t updated anything until niw and
would like tot do so.

How can ik create a rescue cd that would let me undo the updating
process and what files do i need to be on that disk?

I have a seperate /boot partition.
And would like to save user files and e-mails etc..

greets Eelco
