IKR but, Gigabyte BIOS guide? How to set exclusive boot options Z170

[GDavid]

I know it's extremely noob, but don't know where else to look;
 
Have upgraded from GA-EP45-DS4P 9550 8G to an Z170m-D3H and am having trouble trying to work out how to setup exclusive boot options in BIOS so I can boot from Win 10 180G SSD or Win 7 240G SSD.

On newegg's Gigabyte Z170m-D3H page in the reviews tab a reviewer (at bottom of the "reviews") posted the following:

Other Thoughts: I'm not sure if other OEM's have this feature, but the UEFI BIOS allows you to exclusively enable your boot drive, so you can have multiple drives with distinct OS's, and when you choose to boot one, the others are auto-disabled.

Can't seem to find any suitable guides or instruction on Gigabyte BIOS to do what he's saying, I know it's possible to VM it but would rather save the virtualisation overhead....

Could someone please help?

If you hit F12 as you boot than you can choose which drive to boot from. In the past you always install the oldest OS first. The newest would install a boot manager. But the only draw back on this is if you want to remove either OS you might have to jump through hoops to do.

I myself like the F12. Now what OS you want to use more than the other. Make that one the boot drive. Any time you want to use the other just hit F12 and pick that one. The main drive will never change. The only draw back on this if you are doing something like updates & have to reboot. If it isn't the main drive you will have to hit F12 every time.
