How to create a rescue disk?

[James Guarriman]

Hi.

I installed Fedora Core 2. After 2 hours, I suffered a
blackout at home and my PC didn't start, because it
stopped when starting 'email daemon'.

My HD was empty this time, and I decided to reinstall
it
again. But next time I would like to have a rescue
disk.

1) How can I create it?
2) How must I use it when my system is damaged?

Thank you very much.
