I switched to Ubuntu a while back and over time entropy and inexperience lead to a bunch of redundant applications, a very messy directory tree and general slowness. I figured rather than upgrade to 14.04 I would do a clean install.

I created a bootable USB and attempted to reach the BIOS so as to change the boot order. I've tried pressing, clicking repeatedly and holding Esc, Shift, Super, Alt, Fn, Ctrl, F1-F12, Pause, Vaio and Delete, but none worked.

I figured I'd manually disable starting up in Ubuntu with sudo rm -rf /. I just ended up booting in Grub. I took the hard drive out, when booting up it now says:

Operating System Not Found

Do I not have a BIOS or something? What the heck is going on?
