Change the Boot Order in BIOS

Changing the boot order of the "bootable" devices on your computer, like your hard drive or bootable media in a USB port (e.g. flash drive), floppy drive, or optical drive, is very easy.


Turn on or restart your computer and watch for a message during the POST about a particular key, usually Del or F2, that you'll need to press to ...enter SETUP. Press this key as soon as you see the message.

After pressing the correct keyboard command from the previous step, you will enter the BIOS Setup Utility.

All BIOS utilities are a little different so yours may look like this or it may look completely different. No matter how your BIOS setup utility appears, they are all basically a set of menus containing many different settings for your computer's hardware.
In this particular BIOS, the menu options are listed horizontally at the top of the screen, the hardware options are listed in the middle of the screen (grey area), and the instructions for how to move around the BIOS and make changes are listed at the bottom of the screen.

 

Using the instructions given for navigating around your BIOS utility, locate the option for changing the boot order.

Any hardware connected to your motherboard that is able to be booted from - like your hard drive, floppy drive, USB ports, and optical drive - will be listed here.
The order in which the devices are listed is the order in which your computer will look for operating system information - in other words, the "boot order."
With the boot order shown above, BIOS will first try to boot from any devices it considers "hard drives" which usually means the integrated hard drive that's in the computer.

 

If no hard drives are bootable, BIOS will next look for bootable media in the CD-ROM drive, next for bootable media that's attached (like a flash drive), and finally it will look on the network.
To change which device to boot from first, follow the directions on the BIOS setup utility screen to change the boot order.
To boot from the USB you need to bring it to the top and to do that follow the instructions inside your BIOS as to how to change order of any thing.

BIOS will now look for a bootable disc in the optical disc drive first, before trying to boot from the hard drive, and also before trying to boot from any removable media like a floppy drive or flash drive, or a network resource.
Make whatever boot order changes you need and then proceed to the next step to save your settings.

Before your boot order changes take effect, you will need to save the BIOS changes you made.

To save your changes, follow the instructions given to you in your BIOS utility to navigate to the Exit or Save and Exit menu.
Locate and choose the Exit Saving Changes (or similarly worded) option to save the changes you made to the boot order.

Choose Yes when prompted to save your BIOS configuration changes and exit.

Note: This Setup Confirmation message can sometimes be cryptic. The example above is pretty clear but I've seen many BIOS change confirmation questions that are so "wordy" that they're often difficult to understand. Read the message carefully to be sure that you're actually saving your changes and not exiting without saving changes.
Your boot order changes, and any other changes you may have made while in BIOS, are now saved and your computer will restart automatically.

Now the computer shall restart and since you turned the first priority to USB it shall look for a USB first to boot.
