I have a win11 computer that I want to clone/restore to my new trigkey mini. I backed up my old computer and restored to the mini and can not get it to boot. So, I had backed up the mini just in case something went wrong. I retored the mini with it's original backup and now it won't boot that either
To be able to clone Windows 11, you have to use a software free like Clonezilla...

In your case, you must first recover your initial installation, try this.
When you start your "old" PC, interrupt the startup, at least three times in a row, until Windows checks for errors itself. You will then be able to restore the installation.
Try this, hope it works for you.
