Don't know where you get all this just format the drive stuff?, i right click my C drive and only get this message "This drive contains volumes of Windows that you are using, formatting this volume could cause your PC to stop working" so no option to format that drive at all, i also don't get any "quick format" options either, bottom line it will not let me format my "C" drive, but again nobody read my post, my PC was completely locked up, had no way or no way i knew to unlock it, that's the whole point they lock your PC up so you cannot get out and format this do that or whatever else.
what did you see while booting up cold? bios then login screen ? with highjack message was only action computer was doing
then get in bios and change boot to optical drive first, put in windows disk then go to dos or install over top
