I don't have any DVDs nearby at present, but I wanted to make a bootable USB stick and boot my MBP from that to obliterate my 7RC1 and make it the real deal. I can't seem to figure out any way for the damn thing to understand that I have a bootable USB stick with 7 on it, which seems odd because that's how I installed Leopard. Any tips? Or should I run and get a DVD to burn? Ideally I'd like to make this work, so please offer any tips/suggestions you may have.
