Folks, I need some help. I tried to Boot Camp and install Windows 7. After BootCamp Assistant made the partition, I attempted the installation. "No Bootable Device......" came on the screen. after many unsucessful attempts to correct this problem, I gave up on the "Windows Experience". So I purchased a new HD, and thought I'd just load Snow Leopard. Wrong! I'm still getting the same message. If you know what to do, please let me know. Two days ago I had a working MacBook, now I've got a MacBrick.
