Hello everyone, first time on win-raid, i hope you can help :
I’ve been trying for a long time to make Windows 7 work on UEFI (non CSM), so i built a custom iso with USB 3 and NVMe drivers (and UEFI files from Windows 10) but i’ve encountered a problem :
My iso only works on certain computers (mostly desktops), and i’ve a lot of issues to make it work on a lenovo laptop (Lenovo V14 G4 amn). It get past “System is loading files…” but completly freezes at “Starting Windows…”.
I think the problem here is the ACPI chip driver because Windows 7 doesen’t seem to want it bc of energy managment system (i can’t find one compatible with Windows 7). There’s probably another problem with the iGPU wich is not compatible with Windows 7 generic drivers.The CPU is an AMD Athlon Silver 7120U. I’ve already tried so many things to make it work but it doesen’t seem to work on modern AMD laptops.
I even tried UEFI PRO (https://www.reddit.com/r/windows7/comments/ukd3e5/uefipro_windows_7_uefi_iso_for_lazy_people/) but there’s almost the same issue.
I know that the version of AGESA on this particular cpu is a bit weird but i can’t find a solution.
Maybe you guys can help ?
