Hardware: ryzen 5 8645HS rtx4050 rtl8852be
BIOS version F.07
Tested workaround was:
DO NOT use something like VENTOY(broke stage2 discovery), use something like rufus or fedora media writer which worked in my case.
Now that only leaves the hybrid gpus issue (Display quirks under Xen: black screens, forced reboots etc…)
in grub press e to add these boot parameters:
rd.driver.blacklist=nouveau nouveau.modeset=0 xdriver=amdgpu
then press ctrl+x
then after installation just make it permanent.
This only works for the stable official kernel and for some reason fails to load xsession/installer for the latest kernel.
Hope this could prove useful to other.
