I went to install a Debian instance on Windows Hyper-V client in Windows 10. However, when I attempted to start the VM, it would not boot from the cd. Eventually the Hyper-V BIOS gave me a failure to start screen that listed boot devices and their status. The status of the SCSI-DVD device said: "The unsigned image's hash is not allowed (DB)".
Finding information about this error on the internet is proving to be difficult.
