You certainly can and should make drive images as Greg says.
You will not fit an image on a cd - depending how much USED space is on your Vista partition - you might get it on a couple of dvd's - if you use a 3RD party program.
Typically the image will be half the size of the USED space.
The Windows backup image takes a lot of space and is not very flexible
It is included, free, of course and is better than nothing.
There are a couple of free programs that are much better :
Take your pick : http://www.sevenforums.com/software/...tml#post324736 Macrium Reflect FREE Edition - Information and download
Afaik - the free Easeus partition manager is only for 32 bit o/s.
This free one is much better : http://www.partitionwizard.com/download.html
Get the free Home Edition and the Bootable disc.
