In this article, we'll explore how to properly configure your UEFI settings to prioritize the USB drive as your first boot option. By following our steps, you'll be able to boot into FreeDOS and leverage its powerful features in no time.

Step-by-Step Guide to UEFI Bootable FreeDOS USB Stick

Step 1: Download and Prepare FreeDOS

Before we begin, ensure that you have the FreeDOS ISO image downloaded from the official website. Once you have the ISO, you'll need a tool to create a bootable USB stick. Common tools for this purpose include Rufus and BalenaEtcher. Rufus is particularly popular due to its ease of use and wide range of supported formats.

Step 2: Create the Bootable USB Drive

Insert a USB drive into your computer and open Rufus. Follow these steps:

Select the USB drive from the device list. Choose the FreeDOS ISO file in the ISO image dropdown. Select the GPT partition scheme and the UEFI: FAT32 boot option. Click on the 'START' button to begin the process. This will copy the FreeDOS files onto the USB drive, making it bootable.

Step 3: Configure BIOS/UEFI Settings

Before you can use the USB stick, you need to configure your system's BIOS/UEFI settings.

Restart your computer and enter the BIOS/UEFI settings by pressing the appropriate key (usually F2, F10, or Delete). Navigate to the boot order section. In most cases, this will be found under the Boot or Boot Order tab. Move the USB option to the top of the boot order list. This ensures that the computer will attempt to boot from the USB drive first. Save your changes and exit the BIOS/UEFI setup. Your computer should now be configured to boot from the UEFI-compatible USB stick containing FreeDOS.

Step 4: Booting into FreeDOS

With the settings configured, you can now proceed to boot into FreeDOS:

Power on your computer and immediately start the boot process by inserting the USB stick and rebooting the system. Keep holding the appropriate key ( usually F12) to select the boot device during the POST. Once the FreeDOS menu appears, choose the correct entry to boot from the USB stick.

Common Issues and Troubleshooting

If you encounter any issues during the boot process, here are a few troubleshooting steps:

Check the USB cable and ensure it is firmly connected to both the USB port and the USB drive. Verify that the USB drive is recognized by your system. Open the BIOS/UEFI settings again and confirm that the USB is listed as a bootable device. Try using a different USB port or a different USB drive to rule out hardware issues.

Conclusion

Creating and configuring a UEFI bootable FreeDOS USB stick is a simple process that can greatly enhance your system maintenance and testing capabilities.

By following the steps outlined in this guide, you should be able to set up your FreeDOS USB stick and boot into it using UEFI. This bootable USB stick can serve as a valuable toolbox for troubleshooting and maintaining your computing systems. Happy booting!
