    In most cases, the BIOS will not be automatically configured to your device. If you skip this step, your computer will boot from your hard drive rather than from your USB device.

    Pro tip: Many PCs’ BIOS lists the USB boot option as USB or Removable Devices, while some may also offer it as a Hard Drive option. So, if you’re having trouble finding your gadget, you may need to look around a little.

    Another thing to consider: Are you trying to figure out how to boot from USB in BIOS? When you alter the boot information on your BIOS list in terms of sequence priority, your PC will check for new boot information every time you boot it up.

    Please keep in mind that while starting from a USB drive, there may be no prompt to input a key. Typically, it is a self-starting procedure.
