Need help in switching distros
(sh.itjust.works)
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Yes, I have an extra copy of the data in an external hard drive.
In that case simply wipe/re-install and restore your backup. Ideally test that procedure in a VM or something before you wipe.
And while doing that it's best practice to create a partition only for /home. Easy to distrohop.
