@Andymist
First determine if your Windows installation is UEFI or Legacy BIOS based. Clcik start, run, type in msinfo32 and hit enter. Post pic of resulting screen (alt+print screen then right click + paste into the post)

So, BIOS mode is UEFI. Next to check the partition tables - open a command terminal in admin mode and type the following and hit enter after each line:

cd\
diskpart
list disk

does the Windows drive have an asterisk after the disk listing showing it is formatted GPT? (post pic of terminal window)

exit
exit

to get out of diskpart and close the command terminal window.

So drives 1, 2 and 4 are GPT - which drive is the one with Windows on it?

If the Win drive is GPT what size is the EFI partition? Must be at least 200MB to install Mac OS on same drive with Win.
