Why doesn't the computer recognize my USB boot disk?

Why can’t the computer recognize my USB boot disk? This is a common problem that many users encounter when using a USB flash drive to start their computer. PHP editor Zimo is here to answer the questions for you. Usually, there may be many reasons why a USB flash drive cannot be recognized as a boot disk, such as problems with the USB flash drive itself, problems with computer settings, etc. When troubleshooting, you can try re-inserting and unplugging the USB flash drive, checking BIOS settings, replacing the USB flash drive, etc. I hope these solutions can help everyone solve the problem and start the computer smoothly.

BIOS setting problem:

There are two types of U disk boot disks: legacy boot U disk and UEFI boot disk. Legacy boot disks cannot boot in UEFI mode, but UEFI boot disks can be used directly in UEFI mode.

Solution:

1. Keep pressing the Del key (or other keys: F2, F12, esc, etc.) during boot to enter the BIOS.

2. After entering the BIOS, use the arrow keys to switch to the Security option and set Secure Boot to Disabled, which means turning off secure boot.

3. Switch to the Boot interface and set the Boot Mode to legacy Support. Some may be Launch CSM, set it to Enabled.

4. Finally, press F10 to save the settings and exit. When booting, press the U disk startup shortcut key to recognize the U disk startup disk.

Other reasons:

1. The creation of the USB boot disk failed and you need to create the boot disk again.

2. The USB interface has poor contact. You can try changing several interfaces.
