Changing which drive is listed in GRUB?

[wackyvert]

I've got a weird issue here. I have grub all running successfully, but the option to pick "Windows Boot Manager (on /dev/sda1)" does not boot me into windows, rather it starts booting my Windows RECOVERY partition on my big mass storage drive. I have 3 drives, 2 ssds and a hard drive. Linux is installed on the hard drive if that matters. I installed "Grub Customizer", but I have no idea how to create a custom boot sequence and I am unable to find any resources online pertaining to such.

May be best to see details, use ppa version with your live installer or any working install, not older Boot-Repair ISO:
Please copy & paste link to the Boot-info summary report ( do not post report), the auto fix sometimes can create more issues.
