I currently have Windows 8 Beta x64 installed and would really like not to reinstall x86 version just for BIOS upgrade procedure. Is it possible to upgrade BIOS from Windows PE/RE or does it lack some kind of drivers/dlls?
I already did that, in fact, I did a clean Windows 7 install, low level format included. I tried to activate via the slmgr -ilc, slmgr -ipk and slmgr -ato procedure, using the Lenovo certificate and serial, but I think something is missing, since I get a non-genuine installation after I apply the KB971033 update. Am I doing something wrong or missing something?
