Two drives with two operating systems

[chimique]

Hi, I currently have a HDD with a non-genuine version of windows 7 on it. I would like to buy a genuine copy of windows 7, as well as an SSD. I was just wondering if I installed this genuine version of windows 7 on to an SSD how would that interact with the version on my hard drive?
Would there be corruption errors or can I just leave the non-genuine operating system on my hard drive and then tell the computer to boot the operating system that is on my SSD?

The bootleg Win7 will not be an issue because it and all the programs on it won't be available to the new legal Win7 on the SSD you set as the boot drive. Might as well just reformat the HDD drive and use it for storage. Then any programs (games) you install on it will be usable by the new Win7 on the SSD.

But if you are starting anew, why not go with Win10? Win7 will be dropped from support before too much longer. 2020, I think. Not sure of the date right now.

Okay so to do the whole process I should:
-Take out my hard drive and put in the SSD
-Install windows on to the SSD
-Set the SSD as the default drive to run (how do I do that?)
-Put my hard drive back in and boot up the computer
-Format my hard drive to erase everything on it

Is this correct?

Yes, although you don't have to actually 'take out' the HDD. Just disconnect the SATA cable.

The boot drive is determined in BIOS. If you only have one drive connected, the SSD will automatically be the boot drive.
When you re-connect the HDD you may want to check in BIOS to be sure the SSD is still the boot drive. It should be.
