Citadel Activation Software

Create a Bootable USB Thumb Drive

1. Insert a USB thumb drive into your computer.

2. Format a USB thumb drive to the FAT32 file system.

Be sure you backup any files on the drive because they will be erased!.
Ensure that no other partitions or files exist on the thumb drive! If you have multiple partitions on the thumb drive, you may have to use other tools to delete them such as “Disk Management” which is built into Windows 8.1 and Windows 10.

3. Open the ZIP file you downloaded and extract the folder inside to your computer.

4. Navigate into the folder and copy the contents to the thumb drive.

Do not copy the folder itself over to the thumb drive. Your system will probably be unable to boot from it if you do.


You now have a bootable thumb drive. If you require more help, please contact Technical Support. See Product Support.

Configure UEFI/BIOS Settings

You will need to properly configure your BIOS or UEFI in order to properly boot from the thumb drive. To do so, follow the instruction set below that’s applicable to your situation.

1. If you have an option for “UEFI Boot Path Security” or something like it, be sure to change it to Never.

2. Ensure that your “SATA Operation” is set to AHCI

3. If you have a discrete video card, ensure your primary display detection is set to Auto.

4. Disable “Secure Boot”.
