Windows 11 installation restarts as Windows 10

I've upgraded (or tried to) a PC running Windows 10 to Windows 11. All the hardware criteria are met and it happily does the installation. It finishes with the normal screens asking me to restart the system. When it does restart, it does so back to Windows 10, not 11.

Any thoughts, anyone?
 
Do you have 2 hard drives attached to the system? If so, you probably have 10 on one and 11 on the other and you would need to go into the bios and change boot order.
 
No, it's a single drive but is a new one, having been cloned from a 500gb. The attached pictures are of the 1tb (the problem one) and 2tb (which is a separate PC but included for reference) but they have different system drives. I wonder if that's the problem? Perhaps redo the cloning?

I'm not understanding your last post. So you cloned a 500gb drive that had windows 10 on it to a 1TB drive and then updated that to windows 11? I'm not sure why you included the 2tb drive if its in a different system.

When you were installing and it rebooted, did it say anything about rolling back the installation cause of an error? What did you use to upgrade to windows 11?
 
The image of the 2tb was to show the system drives on another PC. Different in number, type and space allocated and use.

There were no messages at all saying it was rolling back. I've updated a couple of machines from Win10 to Win11, and this one was no different - until it restarted and I got the Win10 screens. I used the Win11 assistant for installation.
 
Try making a usb installer by going here and download it. I'm pretty sure you can use it to upgrade to 11, should be like windows 10.

Click on create installation media, you'll either need a dvd or usb but highly recommend a usb flash drive.

Are you sure that it meets the system requirements for 11? Did you run the tool to verify?

Another option would be to do it through windows update. You should see the option to the right to see if windows 11 is ready. See attached.

Once you click that windows should check to see if its ready to download. If it says it is, try it. See attached

Thanks for the suggestions, but they didn't work either. I had a different issue on another PC when trying to upgrade to Win11 which failed (0x80070571) so I'll leave it to later in the year when they aren't being used (they're work machines) and do a clean install on both.
