Windows 7: Need help with dual boot issues please...

Windows 7 Pro 64bit SP1
Need help with dual boot issues please...

Did a clean install of Win 10 Pro recently...everything running good...but tried to setup dual boot with my trusty Win 7 Pro and am having definite performance issues when booting to 7.

I think it has something to do with the attached Computer management jpg...seems the 'system' thinks Win 7 is the main/primary OS/drive...not Win 10

1st to admit I don't know what all the tags mean in Computer Management jpg...but think it's probably that the PC thinks Win 7 is the 'primary' and Win 10 secondary...or something ?

Issue is that Win 10 boots and runs fine...old Win 7 boots...but very very slowly and runs the same way...very slow to change screens...respond to keyboard entries...etc .

Any help with this will be greatly appreciated.

Windows 7

This is straight from the 10 forum: Dual boot 7 and 10.
I never cared for dual boot so I just had an older smaller drive running 7, slapped it in and upgraded
to 10. I play on that a while and when tired or po'd I swap it back. Much easier than imaging, upgrading,
restoring 7 image back again. Whatever works for ya. Later.

Windows 7 Pro x64 Windows 10 Pro x64

Well 10 is clearly on a ssd, is 7 ???

Windows 7 is only C because you are booted into it, when you boot into 10, it will be C.
