Windows 10: Is it possible to use the same Windows license on two different boot drives on the same...

I am interested in setting up two different operating system bootable drives on my computer I'll select boot from the second one through the BIOS when needed and I wanted to know if it is allowed to use the same Windows license on both drives? They would never be used at the same time, it would only be one or the other loaded at a time. They share the same hardware and computer. Just wanted to check before doing this so I don't run into problems.

Windows 7 booting off wrong drive?!?!?

Please move if this is in the wrong place.

I have two hard drives, a 1.5TB drive, and a 160GB drive. Windows is installed on the 1.5TB drive, as are all my files and programs. The 160GB drive has a bunch of old files, and apparently the bootmgr and boot folder. Nothing else is on the 160GB drive, other than media files etc.

If I remove the 160GB drive from the machine, windows refuses to boot, plug it back in, it works fine. The setup with two hard drives I have now is temporary, as the 160GB drive will go into another machine.

My question is, can someone give me a step by step on how to make windows force to boot off the 1.5TB drive, ignoring the 160GB drive in the boot process completely?
I don't know how to do this in Windows 7, on XP I would just run the /fixmbr command and its related ones.

Any help would be appreciated.

Note: I would really really rather not have to wipe and reinstall, I know it can be done without one as I've had this issue with XP before.

Will not boot from a different drive

I am on Windows 10. I originally had two drives, a storage ssd and a smaller boot ssd. I just installed a brand new m.2 in my machine, and installed windows on it. I tried to format my original boot ssd afterwards, but to no avail. The new drive boot into Windows once upon installation, but since then I have been unable to boot into Windows from my m.2, only my original boot drive. It is not listed as a bootable device from my bios, but I can see the Windows, and Program Files folders in my directories when booting from my original drive.

1. How can I boot from my new drive?
   
2. How can I format my original boot drive after I am able to boot from my new drive?
