change from windows 7 to chalet os

Hello, i am still using windows 7pro64bit, but know I will have to change at some point. I do not want to go to w10. My hp envy desktop is 5 years old but has lots of speed and space. Can not afford a new computer. Can I safely and easily move to linus chalet os?
I am ignorant of computer language and workings.
thank you
