add ssd to computer

I have watched a couple of youtube video's on adding an ssd to my computer.
I have windows 10 upgraded free from 7, I have the 7 disk, will the ssd end up with 7 or 10.
Some of the video's make it look easy so I am thinking of trying it.
If I buy an ssd will it have instructions for this process or do I go to youtube, I could not find one in tutorials.
Is this easy to do or hard, what are the dangers, I don't want to break the mechanical drive and have nothing.

I only have questions for you in your decision making, others will have answers.
1. Will the SSD be replacing the HDD or will it be a second drive?
2. Will you want Windows installed on the SSD and the HDD end up being a second or Data drive?
3. How large, what capacity, are the SSD and HDD?

I know how I prefer, download the .iso file or create the USB drive using MCT/Media Creation Tool, disconnect the HDD, connect the SSD and install clean then add in the HDD for Data storage. Since Win10 has already been on the computer it should automatically activate when connected to the Internet.

1. ssd will be 1 and mechanical 2 depending on what I hear on this forum
2. Windows on both if possible, otherwise I guess windows on ssd and hdd for storage
3.ssd will be 128 or 256 since I have only used 85 gbs in 6 years, hdd is 500 down now to 415

that may be better than what I saw on youtube but seems more difficult

That would be called dual-booting, sometimes problematic in the setup. Most folks who use dual-booting have different operating systems or different versions of the same.

I think I misstated what I was going for so I will go this way, clone hdd to ssd, remove hdd and have ssd as only drive.
I may be able to do that with instructions.
I have downloaded reflect free.
Can we start over.
I have windows 10 from windows 7.
I have windows 7 disc.
If I do it properly what will I have on ssd, 7 or 10.

Since you have the Win7 disc and probably the Product Key on the Certificate of Authenticity sticker on the computer I'd put the SSD only in the computer, install Win7, get it activated then install Win10. It has always worked for me but takes some time, not a big issue as the computer is usually someone else's and on my workbench, not in the way of my doing other things.

I follow all but how I upgrade to 10 since it is no longer free, before taking out hdd do I copy that to ssd after 7 is on it

I would try cloning the HDD to the SSD with Macrium Reflect. Shut down the computer and replace the HDD with the SSD and see if it will boot.
