I am following this video:
https://catcoq.com/blog/how-to-create-a-seamless-pattern-in-photoshop 

When I try to open the 10 elements into photoshop,they don't appear like this  screenshot? They appear in tabs above

FYI my computer isnt compatible with photoshop.

Please list all possible ways to get these elements into photoshop? I am a beginner so please write where I can understand it?

I do not understand : if Photoshop is not comptatible with your computer, you cannot do anything.

For the seamless pattrens what is to be understood is the proper way to handle repetition to avoid repetitive squares effect.

You can also creat a simple pattern selecting the wanted part and ask menu edit > use as a pattern
