BIOS TO CHANGE THE BOOT ORDER

BIOS stands for the Basic Input Output System and is often what you'll need to access in order to startup a computer from something other than the hard drive.

Boot Order

Often, the boot order is set by default to look in the optical drive (CD/DVD) for a startup disk. But, if not... or, if installing from a USB flash drive or external drive; you'll need to get into the BIOS to change the boot order.

First Boot Device

Most BIOS' don't react to mouse movements - you'll usually only be using the keyboard to move through menus, make changes and save.

Enter Boot Menu

The POST (Power On Self Test) screen should let you know which key, or key combination, to press to enter the BIOS. You'll see this screen within the first few seconds of booting up (starting), or re-booting (restarting) the computer. Many times entering the BIOS will be called entering the Configuration, or entering the Setup.

run the setup utility

If the POST screen doesn't say how to enter the BIOS, goes by too fast for you to read, or is covered by a logo; try tapping the [ESC], [DEL], [F1], [F2], or [Backspace] keys. Note: don't hold these keys down - just tap them, one at a time while booting, or re-booting.

enter SETUP

If any documentation came with your computer, check that. It also often helps to search the Internet for the manufacturer and model name of the computer plus the word "bios."

Setup

If all else fails; try booting up while the keyboard is unplugged to purposely get an error that may allow you to see the key(s) necessary to enter the BIOS. Sometimes access won't be granted while using a USB keyboard. In that case, connect a PS/2 keyboard and try again.

Note: If you are asked for a password you don't know; open the computer case and carefully remove the "BIOS battery" (it looks like a round watch battery) for 5 seconds or so, snap it back into place and try again.
