Not all USB drives are bootable, and some may not be recognized by certain computers. Using a different USB drive or ensuring that the drive is properly formatted for booting may resolve this issue.

Furthermore, the type of operating system on the USB drive may also cause compatibility problems. Some computers may not support booting from certain operating systems on USB, or the USB drive may not have been properly formatted for the specific operating system. Verifying that the operating system on the USB drive is compatible with the computer’s hardware and that the drive is properly set up for booting can help to overcome this compatibility hurdle.

Boot Order Configuration

When troubleshooting booting issues from a USB drive, it’s essential to check and configure the boot order in the system’s BIOS or UEFI settings. The boot order determines the sequence in which the computer looks for operating systems to boot from, including USB devices. To access the BIOS or UEFI settings, restart the computer and look for the specific key to enter the setup, which is often displayed on the screen during the boot process. Common keys include F2, F10, F12, or Del, depending on the manufacturer.

Once inside the BIOS or UEFI settings, navigate to the boot order configuration section. Here, you can adjust the boot priority by selecting the USB drive as the primary boot device. It’s important to ensure that the USB drive is recognized and listed in the boot order. If the USB drive does not appear, it may indicate a connection issue or a problem with the drive’s compatibility. Save the changes before exiting the BIOS or UEFI settings, and restart the computer to see if the booting issue from the USB has been resolved.
