Most of those are system kexts.i just checked my backup drive and it shows me these kexts in *Backupdrive*/Library/Extensions:
After power on press your boot menu key (usually f12 but YMMV) then select the EFI partition of the USB.still boots into bios whit thumb drive connected or am i missing a key i need to press at start? I m using a Asus Z390 Motherboard
No more ideas.Ok i could get get into Boot menu via F8 but when i choose any of the drives it goes straight to the BIOS
This is the very reason that we make backups.how would you restore? if i cant get into the system
