How to Set Computer Boot from USB Drive

This document shows you how to set your computer to boot from USB flash drive. You can set your computer to boot from USB flash drive by the following ways.

Method 1: Set computer Boot from USB device by Boot Menu

Guide to set your computer boot from USB drive:

Step 1: Insert USB flash drive to computer.

Step 2: Power on or restart computer. When vendor logo appears on screen, press Boot Option Key repeatedly until Boot Option Menu appears. You can find the Boot Option Key for your computer from the following table.

Step 3: When Boot Menu appears, choose USB drive to boot your computer. Tips: Boot Menu may show your USB drive as USB HDD or other name. You can try again to get the right one.

Tips: While your computer is preinstalled with Windows 8/10, sometimes probably you cannot set computer boot from USB drive so easily with boot option key, because UEFI BIOS has replaced traditional BIOS. It seems to be more secured, more fast to boot computer, and maybe you coudn't have enough time to press boot option key when computer logo appears.

Besides, note that this boot menu option may not be present on all UEFI PCs. On some UEFI PCs, you may have to access the UEFI settings screen in a different way - check your PC’s documentation for instructions if you don’t see the button here.

So if this method cannot work for UEFI PCs, please follow method 2, entering UEFI BIOS settings and set USB device as first boot device.

Example 1. Set Dell laptop or computer boot from USB Drive.

Insert the USB stick into a USB port and start or restart computer. When F12 = Boot Menu appears in the upper-right corner of the screen, press <F12>. When Boot Option Menu appears, choose USB stick to boot from.
