How to Boot from USB in UEFI BIOS?
Step 1: Insert newly burned CD/DVD into your computer.
Step 2: Turn on the computer. As it starts it should display an option to enter the system set up menu, or BIOS, commonly reached by keys like DELETE, F1, F2, F10, F12 or Alt+S. Use whichever keystroke is indicated on screen. In some cases your computer may display a graphic while it starts. Typically, pressing Esc will dismiss the graphic and allow you to see the necessary messages.
Find the setting that controls which devices the system boots from. This is usually labeled as the "Boot Order" and commonly shown as a list of devices, such as Floppy, CD-ROM, First Hard Disk, and so on.
Make sure that CD-ROM is selected as a first priority boot device. Make the change, then save and exit. (In case of doubt, you should consult the manual that came with your computer, and/or its motherboard.) The computer should now restart.
Some computers have option to boot once from CD-ROM/HDD/Floppy/USB device. Keep tapping the F8 button at boot time and then choose to boot from CD-ROM when boot menu comes up.

Step 7: When you're done with the BIOS setup program, using the tab and/or arrow keys to navigate to the EXIT menu, select the option for saving the changes you just made, and then reboot. (In many BIOSes, a special key--often the F10 key--will save, exit, and reboot in one step.) . When your computer restarts, it will boot from the USB flash drive.
