Start the Active@ Boot Disk Creator and make bootable media.
Let's assume that the Active@ Boot Disk media has an F: letter in our environment
Using the Windows Search Bar, find and run command prompt as administrator:
Mount the Boot.wim to the \mount directory using the DISM tool
Command: Dism /mount-image /imagefile:F:\sources\boot.wim /index:1 /mountdir:C:\mount
Replace BOOTDISK.KEY in \mount directory with BOOTDISK.KEY in Active@ Boot Disk media (F:\ BOOTDISK.KEY)
Dismount the Boot.wim image, commiting the change
Command: Dism /Unmount-Image /MountDir:C:\mount /commit
