Why does BIOS not recognize USB for the boot?

Nowadays, most users use a USB device as a bootable device to install their OS because it is an easy process to install OS.

Sometimes, BIOS is not able to detect the USB. There are various reasons for causing this problem.

Before you know the reason, first you have to know about the BIOS and its relation with USB.

What is BIOS?

BIOS means Basic Input/Output System. It is the firmware for the booting process and hardware initialization. It also provides runtime services to the Operating System and other programs. In a word, BIOS is pre-installed software on the board for running the PC’s program perfectly.

BIOS basically is an instructor that instructs the basic programs of computers.BIOS also compiles booting and hardware control.

You also need BIOS to configure hardware like Mouse, Keyboard, RAM, etc.

BIOS is pre-installed software. It is installed in motherboard after in manufacture.BIOS set-up utility depends on the motherboard.

Other softwares like OS are installed via BIOS. You need a bootable disc or USB device for installing OS on your PC.

But sometimes, BIOS does not detect the USB to boot the system. There is some reason behind it.

Here I describe the primary reasons for unrecognized USB in BIOS:

  • BIOS does not detect a corrupt USB device. If your USB device is Corrupt or Unbootable, it is never detected by the BIOS.
  • The incorrect boot order is another reason for  BIOS not recognizing the USB. Your PC always chooses the first boot option from BIOS.
  • The USB does not detect by BIOS if the USB port is broken-out or loose. If you connect your USB to a damaged port, it doesn’t connect to BIOS.
  • The old USB version is another reason BIOS does not detect the USB. If you have an old USB like the 1.0,2.0 version, it doesn’t support the recent BIOS of Windows 10 or 11.

These are the main reasons for BIOS not detecting a USB. Now Let’s write about the solution to this problem.
