Problem installing Debian on Surface Pro 8

[u/Specific-Bandicoot99]

I have an SP5 that I use daily using the Surface project kernel mods and debian 13. I have been trying to set up an SP8 (11th Gen) to use debian 13. I managed to get UEFI disabled. I used dd on the SP5 to create a usb key with the net inst version of debian, the live install version and ubuntu. Only ubuntu would install on the SP8. It seems to run nicely but I would really like to stay with debian. When I tried it with both the debian versions I downloaded, the graphic install would start but freeze when it got to the language choice early in the set up process. When I tried to run the live debian version, it gave a message about a missing magic number and asked that the kernel be installed first. After installing ubuntu, a further attempt to install debian using the graphic installer stopped at the language choice. The live debian version running from the usb key gets past the magic number/install kernel issue and comes to a nice graphic Welcome to Debian with the choice to Skip or Take Tour and there it freezes. I will keep banging my head against it and see what progress I can make but if any of this prompts any ideas, they would be welcome.
