It looks like the installation media you have is corrupted. Is it an original disk?

If your installation media is damaged you can get a clean copy from Microsoft

Follow the "Create Windows 10 installation media" options.

Do try to create a bootable USB Drive (using the official tool from Microsoft). It's easier and faster to install.

I agree that it must be installation media error. That can also mean that the drive has problems if the media works correctly elsewhere.

Hope it helps,

I wouldn't bother trying to enable legacy boot. It's clearly a UEFI (firmware) error not a BIOS or an OS error. If you keep getting this message when trying to boot to other installer images (try another one as your next step), you might try booting to a Windows PE disk (or stick or PXE boot if you have PE on there) and seeing if PE can create a new EFI boot sector for you. I have to do this now and then for certain HP desktops in the Prodesk gen 2 and gen 3 families.
