HP USB Key Utility image tool 3.0

To create images of (primarily) HP Proliant Service Packs – now 2020.09 you need a tool from HP to do this. If you search for it, you’ll always get to the 1.7.0 or 2.1.0.0 version, which is not supported for new SPP images or Windows 10 20H2.

You need to mount the SPP ISO and find the USB creation tool under: /usb/usbkey/usbkey.exe to find the new USB Key tool to create bootable disks from SPP images. You need a 16GB USB drive to create this (32GB may also work, but not larger).
