I keep on getting stuck at the Product Key stage of setup. I've tried changing the iso to VLK and retail by editing setupp.ini and still get stuck there. I can't seem to find an OEMBIOS for this. Is there any way to get past this stage of setup? (To clarify: It says the key is not valid if I don't type one in.) Correct me if I'm wrong or just plain stupid. I'm installing in VirtualBox.
