For quick solution I have used Boxes to install Windows 11 and followed How to Bypass TPM and Install Windows 11: A Step-by-Step Guide to bypass hardware checks during Windows 11 install.
This is fine for now, because I only need some quick test solution and then delete Windows virtual machine.
But… this may not be future bullet proof solution, because Microsoft can decide to update some packages that may produce errors in such “hardware bypassed system”.
If/when I need more permanent Windows install solution, I will probably go the rebase route. It looks this is now super easy to switch in Blufin just ujust devmode and select Enable and maybe there is some additional subquestion… just follow it.
EDIT:
What an annoyance to install Windows 11. I haven’t install Windows for a while, now I understand @j0rge, that installation should be fast and without hassle. For example install Windows without Microsoft account How to use Windows 11 without setting up Microsoft account. Then answering all kind of “stupid” questions during installation? Interesting… It looks they want to force users to go through that lengthy n-questions process, to get all kind of users grants to collect as much data as possible.
