+1 everybody here. You should backup first onto an external hardrive or something with (something like) Acronis True Image in case you need to restore. If you don't have a backup strategy time to get one anyway.. :)

I agree about disk imaging but would never recommend Acronis.
Been there ... use it ... it's slow, not as reliable (as Macrium) and ... it costs money.
I've switched to Macrium Reflect ( the free version ) and am satisfied to the point where I'm not even considering an other option. Reflect's boot rescue options are also much more advanced. Bootable USB stick and CD are easily created.
I've tried a lot of them ... Drive Image, Norton Ghost, Acronis ...
and I like Macrium Reflect much better than the others.
