I have a Late 2006 iMac 17-inch 2.0GHz Intel Core 2 Duo. It has OS X Lion installed, the latest version it can run, which is very outdated. I am planning on installing windows 10 32-bit and using the bootcamp drivers for windows 7 32-bit. However, I would like to completely replace OS X. If I install it in CMS then it will take a long time to boot if my info is correct. I would prefer to install it in EFI mode. The mac has 32-bit EFI so windows 10 32-bit should be able to boot and it kind of does.
When I boot a 32-bit install of windows 10 from USB it goes to (loading files...) and after that finishes it hangs on a black screen with blacklight lit. The keyboard is also connected to something because I can turn CAPS LOCK on and off. I am wondering about the possibilities of booting the install in EFI mode or somehow converting my CSM installation into EFI. I am not interested in installing a bootloader to then load windows, like rEFInd, to reduce the boot time.
Thanks in advance for any ideas!
