I've searched extensively and I can not find a straightforward answer that works. I've used my Windows 7 machine to make a USB bootable (command prompt, etc) using these instructions. http://www.intowindows.com/how-to-install-windows-7vista-from-usb-drive-detailed-100-working-guide/ And i've copied all of the Win7 files off of the installation DVD on to the jumpdrive. I've prepared my Mac for installation by installed rEFIt and all the other instructions on the following tutorial: http://www.tech-recipes.com/rx/9136...with-boot-camp-without-an-external-dvd-drive/ So when I have my USB drive plugged in to my MBP and I start it up, holding down option to bring up rEFIt, the USB drive doesn't show up to begin installation. Is there something I'm missing here? Thanks for all your help!
