Recently got a new HP all-in-one desktop.  When a friend set it up, he transferred data from my old Acer computer to new HP one.  New HP is working well.  Now I need to clear hard drive on old Acer computer.  (1)  How should I do this? Pls. be clear, I am not a tech person.  (2)  Will clearing hard drive on old computer do any damage to new computer programs and browsers, data, etc.?

When I click on "Wiping my hard drive clean" the instructions are for Windows 10.  I have Windows 11.
