Grub screen(no image) and Leap 15.4 on windows drive.

I will try to get a picture of the GRUB boot menu that my make clearer what follows:

I have two Windows 10 menu entries in the grub2 boot screen(sorry no image)
one of them opens what I cal a Window 10 trouble shotting screen.
The other opens a Window 10 boot menu that includes Windows 10/Windows7 and a Leap on PATA drive

I can not find BCDEdit in Windows 7 to change things and the msconfig boot tab has little in it to change. And easyBCD has no entries.
Be nice to get it back to just one window item on the GRUB screen(the windows 7 one). ANY HELP IN THAT REGARD IN LEAP 15.4?

Partition table entries are not in disk order.

Attempting to change or move the Windows system reserve boot * causes problems! (it’s ME, so of course it would be a problem for me!).

I know one solution is to reinstall Windows 7(maybe getting rid of all references to Windows 10), Then Leap, and hope the Leap boot menu will be available to get it recognized.
And arduous task I really don’t want to tackle, with 2 other HDDS that have 15.4 on them.

I guess what I am asking is can changes be made in 15.4 to gt back to a single Windows menu item in GRUB menu??

Top two Leap 15.4’s are on /dev/sdb ( see coded areas in previous post.)
