Re: reformat question
The BIOS doesn't have the ability to do a format. When you insert the OS disk, it will format the drive for you prior to installing the OS. You could use a floppy, but I really doubt that you have one.
Humans are the only creatures that won't live up to the their potential. Give everything your all. When you die, die on E.
So I ask you, what do you intend to do now?
