I downloaded Xubuntu debian OS when I got my Lenovo laptop many years ago by booting from a USB and following a tutorial. Throughout the years I've wrecked my OS from my ignorance in deleting files that programs like ClamTK flagged as viruses and malware. A bunch of little things malfunction like volume controls, I can't send files to the Recycling Bin via the dropdown menus, I can't view files to upload from my desktop, etc...
I'm wondering how I can remove Windows 10 altogether, then USB boot a regular non-debian Ubuntu (which I think is more accessible for my knowledge of computers and interface friendly) without bricking my laptop.
Any help/advice is greatly appreciated.
