Hello,

I have a laptop on which I cannot reinstall Windows 7 (I don't know why but the installation fails)

Suspecting a problem with the hard drive, I am trying to format it
So I created a bootable USB stick with MS-DOS (no floppy drive on a laptop) that contains Format.com, which is supposed to allow me to format drive C: with the command format c:

Booting from the USB works, but when I enter the command, I get the following error:
"this program cannot be run in DOS mode"

I really don't see what could be causing this.
Do you know how to fix this error or suggest another way to format my hard drive?

Thank you

Configuration: Windows 7 / Firefox 12.0
