We can search for our flash drive by using the list disk command. In the diskpart terminal enter the following command. Find the Disk Number associated with your flash drive.
In my case I was able to identify my flash drive as Disk 2. Select the flash drive as the current disk by using the following command, replacing the disk number with your own. Once we have confirmed the disk has been cleaned you can remove it from your current computer and plug it in to the Offline Root CA.

Enter the password and confirm it. When asked for an encryption mode select New encryption mode and click Next.
Ensure the Run BitLocker system check box is checked and click Continue. Upon rebooting you will be prompted for the password to unlock the drive.
Enter your BitLocker password and press Enter. Ensure the role installed sucessfully and that we see the Success Code as True. In your Administrative PowerShell prompt define the following variables:.
