I don't have a disk whereas I installed Windows 8 onto my laptop using the offline installer from Microsoft's website and I have no clue how to do the secure boot because once again I don't have a laptop that came with Windows 8 so I don't have that kind of BIOS that I know of isn't that only SEFU or whatever it is? I have no idea but I don't know what to do because I have waited over 3 hours and still nothing.
