I'm running OS X 10.8.4 on my Hackintosh on a SSD. I installed Windows 7 on a 1TB HDD, and when I installed each of them the other OS's hard drive was unplugged. After I completed installation of Windows 7 I powered down and replugged in my drives and turned my computer back on. Chameleon/Chimera detected I had OS X and Windows 7 to boot to. I chose Windows 7 and was prompted with a screen that said my bootmgr was missing. I boot into OS X and start googling but I'm coming up with stuff that was not my problem. I figure OS X may be doing something to it, so I unplug my SSD and try to reboot. Same thing. Reset my BIOS to stock settings, still nothing. Try to repair it from the boot CD, and I still get nothing. I can't even format the disk because it's greyed out or that Windows couldn't be installed to the disk.. Perplexed I took the hard drive to another computer and ran Disk Management and discovered it had a 100 GB EFI partition on it that was protected. After using the command line to clean out the HDD entirely, I took it back and rehooked it up and install went off without a hitch. Kind of nervous to plug in my SSD now for fear of screwing over my Windows installation again.
So what happened? How do I get it so Chimera or OS X doesn't install a EFI partition?
