I'm assuming you disabled your 2nd and 3rd boot device in your PC's BIOS.
The simple answer to this is to go back into the BIOS and select Advanced Setup and select 2nd boot device. The options there should be something like HDD (your hard drive) CD (your cd drive) Floppy (your floppy drive) and there may be other options as well. Just select HDD. You may also want to select a 3rd boot device while you are at it. Once you have done the changes to the BIOS, save the settings (usually F10) and reboot.
