@ai6yr One option for those who don't want to start off by reformatting, is creating a bootable USB version of Puppy Linux.
Goto https://PuppyLinux.com. You grab an iso and burn it with something like Rufus on Windows to a USB, then boot it and you can either keep running it off USB stick or install it anywhere.
Works on any computer where you can tell the BIOS to boot from USB.
