If you’re having trouble getting your USB device to work properly, knowing how to identify it in BIOS can help.

Here are the steps you need to take.

The guide below explains how to find your USB drive in BIOS and provides tips on how to access it. For most users, locating the USB drive in BIOS should be simple and straightforward.

However, if you are experiencing difficulty finding the USB drive, consult the instructions provided below.

Here’s how:

If you’re looking to boot from a USB drive, there are a few things you’ll need to check in the BIOS first.

First, check to see if your BIOS has a Boot Menu option. If it does, enable it and then try selecting your USB drive from the list of boot options.

If your BIOS doesn’t have a Boot Menu option, you’ll need to check to see if it’s set to boot from USB devices.

This can usually be done by going into the BIOS settings and looking for an option that says something like "Boot Device Priority" or "Boot Order."

Once you’ve found this option, make sure that USB is selected as the first priority. If neither of these options are available in your BIOS, unfortunately it’s likely that your BIOS does not support booting from USB devices.

Reasons Why You Can’t Find USB In BIOS

There are many reasons why you may not be able to find your USB drive in BIOS. I will go over some of the most common reasons and how to fix them.

Keep in mind that while these solutions may work for some users, they may not work for everyone.

These are the reasons:

USB Is Not Bootable

One potential reason why your USB drive is not appearing in the BIOS boot options could be because it is not set up to be bootable.

To make a USB drive bootable, you will need to format it using a bootable disk utility such as Rufus or Etcher.

Once the drive is formatted, you can then copy over the necessary files to make it bootable.

If your USB drive still does not appear in the BIOS boot options after following these steps, then it is likely that the BIOS is not configured to look for USB drives as potential boot devices.

You will need to check your BIOS settings and make sure that USB drives are enabled as bootable devices.

Improper Boot Order

One of the most common reasons why you might not be able to find your USB drive in the BIOS is because of an improper boot order.

If your computer is trying to boot from a different device before it tries to boot from your USB drive, then you won’t be able to see or access the contents of your drive.

To fix this, you’ll need to change the boot order in your BIOS settings.

Look for a section called "Boot Order" or something similar, and make sure that your USB drive is listed before any other bootable devices.

Save your changes and restart your computer; your USB drive should now be visible in the BIOS.

Faulty USB Drive

A faulty USB drive can be a reason why you won’t find the USB in BIOS. The USB drive may not be properly plugged into the computer, or it may be defective.

If you’re having trouble finding the USB drive in BIOS, check to make sure that it is properly plugged in and then restart the computer.

If the problem persists, you may need to replace the USB drive.

Faulty USB Port

If you have a faulty USB port, it can cause your computer to not be able to detect the USB in BIOS.

This can be a big problem, because if you need to use the USB in order to boot up your computer, you won’t be able to do so.

In order to fix this, you’ll need to either replace the USB port, or try to use a different USB port.

If you have multiple USB ports, try plugging the USB into a different port, and see if that works. If not, then you’ll need to replace the faulty USB port.

USB Ports Are Disabled

One of the possible reasons why you won’t find the USB in BIOS is that the USB ports are disabled.

This can happen for a variety of reasons, but one common reason is that the USB ports are set to Legacy mode instead of EHCI (USB 2.0) or xHCI (USB 3.0) mode.

To fix this, you’ll need to go into your BIOS settings and change the USB mode.

Can BIOS Detect USB?

The answer is yes, the computer’s BIOS can detect USB drives. This is because the BIOS is responsible for detecting and initializing all of the computer’s hardware, including the USB ports.

If the BIOS did not support USB, then the computer would not be able to use any USB devices.

To confirm that the BIOS can detect USB, you can try plugging in a USB device into the computer and see if it is recognized.

If the device is recognized, then you will see it listed in the BIOS settings. If you do not see the device listed, then it is possible that the BIOS does not support USB or that the USB port is not working properly.

How To Get USB To Show In Boot Menu

One way to get a USB to show in the boot menu is to go into the BIOS settings and enable the option to show USB devices in the boot menu.

This will typically be under a section called Boot Options or Boot Order. Once this option is enabled, save your changes and exit the BIOS.

Your USB drive should now be listed as a bootable option. If it is not, you may need to restart your computer and try again.

Another way to get a USB to show in the boot menu is to use a bootable USB utility such as Rufus.

This will create a bootable USB drive that can be used to start your computer. Once Rufus is open, select your USB drive and the ISO image you want to use.

Make sure the option to Create a bootable disk using is checked and select MBR for BIOS or UEFI computers.

Click Start and wait for Rufus to finish. Your USB drive should now be bootable.

To boot from it, insert the drive into your computer and press the key shown on screen to enter the boot menu. Select your USB drive from the list and press Enter to boot from it.

BIOS USB Settings

On most computers, you can access the BIOS settings through the computer’s built-in menus.

To access your BIOS settings, you’ll need to press a key on your keyboard when your computer starts up.

This key is typically one of the F keys (F1, F2, F3, F4, F5, F6, F7, F8, F9, F10, or F12), but it may also be the Esc key or one of the function keys (e.g., Fn+F1).

If you’re not sure which key to press, look for a message on your screen that says "Press ____ to enter BIOS." Once you’re in the BIOS, you can navigate through the menus using the arrow keys on your keyboard.

Make sure to save your changes before exiting the BIOS.

To change the BIOS settings for USB, look for a menu called "USB," "USB Settings," or something similar.

In this menu, you should see options for USB legacy support, USB ports, and other USB-related settings. Make the changes you want, then save your changes and exit the BIOS.

How To Enable USB Ports In BIOS

Most computers will have their USB ports enabled by default in the BIOS, but some older systems may have them disabled.

If your computer doesn’t have its USB ports enabled, you’ll need to change a setting in the BIOS to fix it.

Here’s how:

  1. Restart your computer and press the key that enters the BIOS settings screen. This key is usually F2, F10, F12, or DEL.
  1. Once you’re in the BIOS settings screen, use the arrow keys to navigate to the "Advanced" tab.
  1. Find the "USB Configuration" setting and change it from "Disabled" to "Enabled".
  1. Save your changes and exit the BIOS settings screen. Your computer will now be able to use USB devices.

How To Disable USB Ports In BIOS

Assuming you would like to disable USB ports in the BIOS to prevent data transfer:

  1. Enter the BIOS menu by pressing F2 during startup. This might be different for your computer, so check your computer’s manual for the right key to press.
  1. Use the arrow keys to navigate to the Advanced tab.
  1. Use the arrow keys to navigate to the USB Configuration option.
  1. Press Enter to select the USB Configuration option.
  1. Use the arrow keys to select Disabled, and then press Enter.
  1. Press F10 to save your changes and exit BIOS Setup. Your computer will restart automatically.

How To Identify Your USB Ports

Device Manager is a tool that can be used to view and manage the devices and drivers installed on your computer. To identify USB ports through Device Manager, follow these steps:

  1. Open Device Manager by pressing the Windows key + X on your keyboard, then selecting Device Manager from the menu that appears.
  1. In the Device Manager window, find the section labeled Universal Serial Bus controllers or Ports and expand it.
  1. Under Universal Serial Bus controllers or Ports, you should see a list of all the USB ports on your computer. Each port will be listed with its corresponding number.
  1. If you’re not sure which port is which, you can unplug each device from its current port and plug it into a different port. The device will then show up under a different number in Device Manager.
  1. Once you’ve identified all the USB ports on your computer, you can close Device Manager.
