Resolved W10 won't let W7 boot

I got W10 installed and ran a few checks on it. I am now installing some other programs for AV and recording and such. They are not a problem. When I boot the PC it starts on W10 despite the fact that I set the boot order to start W7. A third party needed to fix it? Suggestions? In case it matters...I have both OSes hooked up to same motherboard as I want it to be dual boot. Some games are playable, but some will need to be downloaded specifically for W10 or they crash. If I go into UEFI to boot the PC, I can get W7 to come up, otherwise it will ignore my boot sequence selection even though I did it in the UEFI.

 

What was the answer to your problem?
Posting the fix may help others who run into the same predicament.

 

And why are you installing an AV? The one built into windows is excellent and highly relied on..

 

MrBill, AV = Anti-virus OR Audio Visual ???
