dual boot windows 7 and 10

Solution
This is my setup. I unplugged the Windows 10 and all other drives when I installed Windows 7 on the second SSD. Once Windows 7 was all setup and running with updates applied, I shut it down and plugged the other drives back in. I made sure the Windows 10 drive is my default boot device. Now when I want Windows 7 I just hit my boot option key, F12 in my case, and choose the Windows 7 drive.
Just have to be careful when either drive updates Windows. I have had my Windows 7 drive update and then my Windows 10 drive wouldn't boot. now I just don't install updates unless the other drive is unplugged.

ESFRAME:
To prevent issues it's adviced to install a second version of Windows with only the blank HDD/SSD in the computer (First OS drive removed or disconnected). Later when you add the previous HDD/SSD to the computer, boot the OS you want to have as default, using the BIOS boot drive selection and install EasyBCD on it, to create the Windows dual boot.
BadAsAl:
When Windows is installed on GPT partition table, the installation can take several partitions (Boot, OS, Recovery, System Reserved) that can be set on a second HDD... this seems like what can cause updating one OS can affect the other's boot process. To avoid this type of issue, it's best to install when a single OS drive is in the computer. What you can do now is find out which partitions belong to Windows 10 and which one to Windows 7, and move them to the right SSD. I don't exactly know how to move them but I'll look for the information and post it here*.
You can use EasyBCD to edit the bootloader and create the Windows dual boot selection screen, and you can stop using the BIOS boot drive selection screen.

*This should help "relocate" (at least) the Boot partition or the Boot files contained in it.

Thanks for the help, want to make sure that I can actually install my windows 7 (purchased with key) even though I originally did the free upgrade to windows 10 (I have since upgraded to Windows pro (new purchase with key) right now windows 10 pro is on a Samsung 850 SSD and plan to load my windows 7 onto my other SSD (Samsung 840) and set up the EasyBCD, on the default windows 10 pro, does that mean go ahead and load EasyBCD in advance ?

Sure... you can install EasyBCD on Windows 10 at any time, even if there's nothing to add in dual boot... it's not just for dual or multiple booting. It can be used to repair or restore the Bootloader (BCD file) from within
windows.
