My grandfather gave me his old compaq pc a few years back and its just full of garbage so i want to restore it back to the original settings (wipe the fucker completely clean)..i have the stuff that i want to save already backed up to an external but i dont have any of the original install or recovery disks that came with it...is there a way i can restore it without the disks? ive tried F8,F10, and F11 all at the startup but still no progress. I also tried finding a recovery partition or something on the machine but was unsuccessful there too. How do i do it?
