i have win7 64 bit home, the hdd came from an acer i had i still have the product number but want to wipe my hdd and re install everything fresh.I don't know how i would go about that ive never really dove into the software part of computers.
try this. im assuming you have an acer computer. create recovery disks and use them to reinstall windows. without knowing what model computer you have this is the best i could do.
