I partitioned in bootcamp and then started to install Windows but got an error at the selection of drive to install since I forgot to format the partition to NTFS. Getting error that can't install Windows to FAT. Now I can't eject the windows disk and I'm stuck in an install loop that I can't get out of. Can't get any reboot options, eject key doesn't work and can't get back to Mac OS. If I power down it just boots up to the Windows disk. I'm a noobie on Mac so be gentle. I have MacBook and can't tell you much more than that since I can't get to OS to see system info.
