Q: Win7 hangs between install and configure on iMac
Hi, everyone --
I have an older (2010) 27-in iMac running Yosemite, 4 Gb Ram and 1 Tb HD. Trying to install Windows 7 via Boot Camp, with original Windows 7 Home Premium 64-bit install CD/DVD. Per instructions with Boot Camp made .iso file and installed it on a USB flash drive, to which I also had Boot Camp download support software. Installation seems to go fine until last step of Win 7 install from CD -- but just after reboot following "Finishing Installation", where I assume it's supposed to go to the Configure stage (between #s 6 and 7 on the Boot Camp instructions), it simply goes to a black screen and stays there. I've tried powering off and doing an option-reboot to select the Windows partition, but it does the same thing -- just an inert black screen. I've tried starting in Safe Mode (several flavors), but Windows says Windows can't complete installation in Safe Mode, so restart, whereupon -- you guessed it -- black screen. I've spent the better part of two days trying to get this to work and am feeling lost. Anyone able to offer some help?

The primary issue seems to be a GPU issue.

Even though you have a 27-in 2010 iMac, you should look at Boot Camp: iMac displays a black screen during installation of Windows 7 - Apple Support.
