Windows 10: W10 Duel Boot problem

I have a Dell Model 9020 Small Form computer that I am working on for a friend.

First I have been Duel Booting Windows & Ubuntu for years on different computers and have never run into this problem.

The Dell 9020 has W10 Pro on it & it opens fine. When I install Ubuntu 20.04 on the HD I start having a problem with W10.
The first time I open the Duel Boot W10 will open as it should & so does Ubuntu. The next time I open w10 it takes several seconds to open. After that every time I try to open W10 it shows a blank screen & takes longer & longer to open, until it won't open at all. Ubuntu opens every time as it should.

I have tried clean installs of both OS's on several HD's with the same results.

Thanks for any ideas as to what I should do.

You can but make sure to have an image backup of your 7 (or at least know where to find your recovery media for 7 just in case) and your important data. Play it safe.
If you know nothing about restoring back ot fixing boot issues, I suggest not to do it (or do it on virtual machines). But if you think you know enough, then have fun!

They do tend to "duel" and fight for the boot programs. Check you can boot into both successfully to make sure as others have had issues dual booting with that. One OS or the other may try to take over...
