So I finally picked this up after not using Windows for quite a while. The install doesn't seem to work.

After following your steps above (delete, GUID, partition as OSX), I'm using this guide to install: http://www.sevenforums.com/tutorial...e-firmware-interface-install-windows-7-a.html

The problem is that when I delete the existing partitions and then create new (steps 7-8), I don't get 3 partitions as the guide assumes, only 2. The MSR partition is missing, and I only see the system reserved and primary.

Am I missing something? Is there a workaround? How do I get the essential MSR partition? Thanks!!

Update: After trying 3 times, Windows finally installed UEFI! But it still won't boot UEFI. In my BIOS boot options it says the drive is UEFI, but in Clover my only option to boot Windows is Legacy (which does not boot).

I'm sure there is a simple step that I'm missing, and most of the guides I've found seem to assume a lot of previous knowledge. If you can point me toward a good guide to make sure I'm not missing any of the basics, I would appreciate it. Thanks!!

Did you look at the two guides pinned at the beginning of the MultiBooting forum?

Hello,
Do you think this could work on a MBPro15" mid 2012, installing windows 10 on an external Thunderbolt SSD?
I had success installing Windows on an MBR formatted SSD. It only can Boot if i unplug my Mac internal disks...
I have read on Macrumors that my laptop with Ivy Bridge cannot handle UEFI, since it will only work on more recent hardware such as Haswell i7 chipset? Let me know what you think about?

Use Apple Bootcamp app to set up Windows on a MBP. The methods here are for PC installations only.
If having problems with Apple apps on "real" Macs or installing Windows with Bootcamp see the Infinite Loop forums.
