If you see the following screen when you start your Windows 11/10 computer, then this post will be able to help you. The screen is known to appear in HP PCs with UEFI and offers the option to fall back to a Legacy Boot source when needed. You receive this screen because either something is wrong with the boot order or your boot device is missing.

This screen is also called the Boot Device Options menu; it lets you select a UEFI boot source, such as Windows Boot Manager or a Network card, or a Legacy boot source, such as the hard drive or CD/DVD drive. In this post, we discuss the following aspects:
