Many thanks!
Think to save the hassle, I just get a new SSD for installation of Win 11.
In case anything happened or I don't like Win 11, I can still slot back the original SSD for use.
I have the NVME SSD enclosure, so can do file transfer from the original SSD if Win 11 installation is successful on the new one.
If that's the case you can just install Windows 10, by than when Win 10 support end
than upgrade to Win 11.
Support will not end so fast maybe 1 or 2 years.
