✔ Best Answer
The easiest way to do this is to use the non-commercial version of EasyBCD. Connect both drives, set the BIOS to boot from the disk with Windows 10 installed (the exact details depend upon your motherboard - the manual will explain), and install EasyBCD. When you run it it should find both installations and allow you to set up a boot menu.

Or you can use a 3rd party boot manager: http://gag.sourceforge.net/

I have a similar setup on this machine.
If I need win-7 (emergency case) I simply press the boot-menu key at post and boot from the drive (OS win 7). Otherwise it will continue boot Win 10.
Have extended the POST timeout waiting for F2 or DEL key pressed to 5 secs.

"....2 HDDs Win7+Win10- need 1 on c: and 2 on d: ?"
Just a note:
When you are in Windows 7, it will consider its primary drive as C drive and a different letter for the other drive.
When you are in Windows 10 it will consider its primary drive as C drive and a different letter for the other drive.
I recommend using labels for each drive which will be less confusing. Right click on a drive in Computer and rename it, the letter will not change but if in both systems you call one Win7 and the other Win10 then you keep them straight. Label them in both systems the same way.

You have to be a little bit crazy to keep you from going insane.

Personally, I always hide the other OS partition (unassign its drive letter using Disk Management) to avoid unwanted interactions between the two OSs.

That is a thought... As long as you do not plan on sharing any files between them.

I keep a separate partition for any data I wish to share between OSs.
