I just bought windows 7 home premium !!! GO ME !!! Got it installed and updated drivers and all. So now i want to save this point NEW AND PERFECT. So im going to make a system image but....

I do not know how much space i need to partition for the system image.

I do not want to partition 100gbs and it only be 32gbs. hence wasting space....
How much do i need to partition? It doesnt have to be exact. but id like to be at least within 1gb of what is needed.

I have a 586gb hard drive. I know how to partition and set up the system image.

THROW ME SOME NUMBERS!

Thanks
