I've got an Intel-based MBP with Lion and figured for the heck of it I'd try to boot camp the Windows 8 developer preview. It was my first time fooling with boot camp and everything worked until I got to the installer. I had a DVD for Win8 and burned the boot camp drivers onto a CD. Everthing went fine until the second screen of the install; Windows told me it couldn't find any drivers for my CD drive. I figured they might be on the driver CD, and the Windows installer noted it expected me to eject the install CD anyway.
Except since the boot camp drivers weren't installed, the eject key for the optical drive doesn't work. So I sighed and rebooted. Now I can't boot into Mac OS because it expects to boot from the drive. Holding option during reboot lets me pick the right hard drive, but it's stuck in a boot camp loop and won't do anything but complain there's no bootable media. Yikes. So I'm restoring Lion and that may or may not work, I'm sure eventually I'll talk the machine into booting again.
Since I'm dumb, I'm going to try again later. Maybe putting the drivers on a USB drive, or using a bootable Win8 USB drive will work? Maybe someone can teach me some voodoo to eject the disc? Would it have been so much trouble to let the drive have a hardware eject button?
