1. Understanding the Issue of USB Not Showing in BIOS Boot Options
If your USB drive is not showing up in the BIOS boot options, it can be frustrating, especially when you need to boot from it for system recovery or installing a new OS. This issue is typically related to settings in the BIOS, the USB drive itself, or a compatibility issue between the drive and the system.
In many cases, a few simple troubleshooting steps can resolve this issue and get your USB drive recognized in BIOS boot options. Let's go through these solutions in detail so you can easily get back on track.
2. Check Your USB Drive for Potential Issues
Before jumping into the BIOS settings, ensure that your USB drive is working properly. Here are a few checks you can perform:

Try the USB Drive on Another Device
Sometimes, the issue may not be with your computer but with the USB drive itself. Plug the USB drive into another computer to confirm if it is functioning properly. If the drive doesn't show up on a different system, there may be a fault with the USB drive.
Check for File System Compatibility
Make sure the USB drive is formatted in a file system that the BIOS can recognize. For example, many BIOS systems only recognize FAT32, so if your USB is formatted as NTFS or another file system, try reformatting it to FAT32.
3. Verify BIOS Boot Settings
BIOS settings are crucial in determining which devices are available for booting. Here's how you can check your BIOS settings to ensure that the USB is set up as a bootable device:
Enter BIOS Setup
To access BIOS, restart your computer and press the appropriate key (usually F2, F10, DEL, or ESC) during startup. The key may vary depending on the manufacturer, so refer to your system's manual if you're unsure.
Check Boot Order
Once inside BIOS, go to the Boot menu and ensure that the USB drive is set as the first boot device. If not, change the boot order by moving the USB to the top of the list. Save your changes and exit the BIOS.
4. Enable Legacy Boot Support in BIOS
Modern computers often use UEFI (Unified Extensible Firmware Interface) instead of legacy BIOS. UEFI sometimes doesn't recognize older USB drives, so enabling Legacy Boot Support in BIOS can be a useful step.
Access Advanced BIOS Settings
In the BIOS setup, navigate to the Advanced tab and look for a setting like "Legacy Boot," "CSM (Compatibility Support Module)," or "UEFI/Legacy Boot." If the option is disabled, enable it to allow BIOS to recognize older devices.
Save and Restart
Once enabled, save the changes and restart your computer to check if the USB drive now appears in the boot options.
5. Update Your BIOS Version
Outdated BIOS versions can sometimes cause compatibility issues with certain devices, including USB drives. Updating your BIOS can resolve these problems and improve hardware compatibility.
Check for BIOS Updates
Visit your motherboard or laptop manufacturer's website to check for the latest BIOS update. Be sure to download the correct version based on your exact system model.
Follow Update Instructions Carefully
BIOS updates are delicate processes, so it is essential to follow the manufacturer's instructions closely. Incorrect updates can cause irreversible damage to your system, so proceed with caution.
