|It's best not to guess which key gets you into setup. Check your manual. You need to press the proper key at the proper time. If you really can't get into bios setup then it's not a software problem on the hard drive since getting into setup occurs before the OS on the hard drive starts to boot up. |
And if you can't boot up with anything, how are you going to load a program to wipe the drive?
I suppose you could temporarily disconnect the hard drive and see what happens. If there was a hardware problem with the hard drive, disconnecting it should at least allow you to get into setup to change the boot order.
