Casper image backup - booting from a UEFI computer

I had this question after viewing Cloning a Hard Drive with Casper.

I made a bootable backup image of a Windows 10 computer with UEFI technology  using Casper and an external USB hard drive as the destination.

I tested the backup by changing the boot order to put the external drive first. Unfortunately, the Windows logo appeared but that is where the boot process got stuck. Any tips on booting from an external drive? UEFI seems to complicate things. Thanks.

Hi Wells,
The images that Casper makes ("Create Image") are not bootable. Only the clones ("Copy Drive") are bootable. An image is simply a file that is stored on another drive (such as your external USB hard drive) — the image stored in the file system is not going to boot (for either BIOS or UEFI). Regards, Joe

The first post selected makes a point that images are not bootable — they are simply files stored in the Windows file system on any drive. The second post makes a point about booting from an external drive. Both are helpful for the question asked, so I'm splitting the points evenly between the two experts who participated. If the author means something else, such as BIOS/UEFI issues about booting from a clone (not an image), then I recommend posting a new question.
