Uninstalling windows 8?

[*= WildCat =*]

In a full format, each sector on the hard drive is checked for errors and a one-pass write-zero is also performed. A quick format skips the bad sector search and basic data sanitization, personally I prefer full format

QF will leave behind remants of a former os. It's always prudent to do a long format. If a long format is not avaible on the os disc, then put a small linux package on a thumb drive. Boot to the bios and change the primary boot device to the thumb drive then save and exit. When the system boots it will load the linux os. Smash the partition and format the drive.

I too use a linux live os from a usb drive to format.. that's an easy way.. also have a tool ontrack disk manager which i found the best for disk managment also for zero filling etc..
