Hello,
looking at the screenshot, the ubuntu deployment is starting in a WinPE environment that is only for Windows deployments.
It could be that your computer is a UEFI target booted on a bare metal server with the option “WinPE direct boot for UEFI target” (and in this case, to deploy a linux bare metal profile, you have to make sure that this option is disabled on the bare metal server and that the target computer has the option “Secure boot” disabled) or otherwise it could be that a WinPE deployment media is being used to start the computer to deploy.
Thanks.
