You'd have to install the HDD in another computer and format, unless you have a utility that you can boot from CD (hard drive manufactures make boot disks that you can use to format, but you have to buy them).
What's the rush? Feds knocking at your door?
oo ic , no i wanna get this computer done for my brother for his Bday, but if the feds were coming id flush down the toilet lol
