I'm doing a clean install now on an old laptop without SSE4.2....
First issue was that it couldn't even boot from the standard 24H2 install USB made by the MCT. It gets as far as the Windows logo, then reboots before it even starts the spinning 'loading up' circle.
Second attempt was with my hybrid 23H2/24H2 USB. That at least copied all the files, set them up and got to the first reboot. Same issue, it shows the logo, but then reboots before the circles appear.
...try it in another old AMD laptop that has POPCNT, but no SSE4.2, only SSE4a. This one stalls at the Windows Logo, no spinning circle, but no reboot either....
Yep, seems SSE4.2 is essential....
