In the system BIOS you can tell the computer to "look at" a drive to boot from first . There you can select to boot from a removable drive, usually a floppy disk or USB flash drive(this option is found on most Linux systems). You can also choose to boot from a CDROM drive or Hard Disc(you hard drives).
This is what all my system say and the ones I repair:
1. Removable Drive -- Usually a floppy drive (an emergency boot disk) is what it is talking about here.
2. CD-ROM Drive -- I have this set at two so I can special disks before I get to the desktop or dashboard(Mac).
3. Hard Disks -- This is your hard drive.
its called a "boot-up"

You change the boot priority of a system by changing settings in its BIOS setup. The computer's first hard drive is usually the default first boot device.
When it finishes booting. (Starting Windows\Mac OSX\Linux\Other)
My first guess would be a bad switch.
A hard boot or cold boot is the process of starting a computer system from the power-down state. Another one type of booting is warm boot, which is restarting the sytem through OS.
