I’m considering switching to linux but I’m not a computer savvy person, so I wanted to have the option to switch back to windows if unforeseen complications (I only have 1 pc). Is it just a download on usb and install? And what ways can I get the product key or “cleaner” debloated versions.
If you have a flash drive and an external disk you can boot into Rescuezilla (a disk cloning/backup/restore distribution) using the flash drive, save/backup your OS disk as an image in the external disk, and restore it as needed. After restoration, you will have your OS disk as it was at the time you saved it.
