My PC boots to Windows 10 Pro (which is on my SSD) just fine without my 1TB HDD hooked up (has Windows 7 Pro), but when my HDD is installed, it attempts to boot Windows 7. Earlier, I had to restart my computer, and when I did, it wouldn't load W10 at all. I can't figure this out for the life of me.

Formatting either my SSD or HDD is not an option

I'm still learning how to use and navigate through UEFI, since my old ASUS M4A78T-E didn't have UEFI. I have no clue where that is.

Still unable to do anything. It keeps showing Boot Manager (for Windows 7), not the Microsoft Windows I want.
