Does anyone else have this problem?

On my desktop computer I have three hard drives. Drive A is for files, 
drive B is for Linux (Mint 17.3), and drive C is for Windows 10. In the 
Linux mode, I connect drives A & B, C is disconnected. In Windows mode, 
only drive C is connected (I don't trust Windows anywhere near my 
permanent files).

On my Windows drive, I was using Win 7. After upgrading to 10, My boot 
process for Linux is very complicated. Windows 10 altered my boot 
process so that it starts very quickly. When I switch over to Linux, I 
have to physically go to the boot menu to choose Linux, if I don't I get 
a blank screen.

I have an MSI Z97S SLI Krait edition motherboard. Any ideas how I can 
get Linux to boot properly?
