Well, I don't know what kind of problem your having but the first thing you need is an image prog.

Norton ghost is popular, I use a product call drive image.

The procedure is
Boot from a floppy
Select create image
Source=my hd
Destination=my cd writer
Hit go


To restore the image the procedure is
Boot from a floppy
Select restore image
Source=my cd reader
Destination=my hd
Hit go
