I want to dual boot win 7-64 bit and win 10-64 bit from separate drives. The OS is already installed on both of these hard drives. Win 10 is installed on a Samsung Evo 850 SSD drive, and Win 7 is installed on a Western Digital SATA drive. This is why I purchased Easy BCD, but I can't get it to work. First, I started out with EasyBCD installed and configured on both drives. Then I tried it with EasyBCD on the Win 10 drive only. Neither of these configurations allowed the dual boot to work correctly. Now I am going to try putting EasyBCD on the Win 7 drive only. I was reading on google that Windows 7 does not play well with newer versions windows unless you are doing a fresh install. This is what I thought EasyBCD was supposed to solve. Can someone please help. I've wasted my whole weekend on this. All of the user guide help and youtube tutorials seem focused on dual booting Windows with Linux, Mac OS and other open source platforms. I don't need win 7 and win 10 to share data or access each other, I just need to find a way to make them either dual boot or just ignore each other during the booting process. In other words, is there any way to make Win 10 ignore Win 7 when booting into Win 10 and vice versa. Make Win 7 ignore Win 10 when booting into Win 7.
