Welcome to the club! My advice is, after you’re done with the installation, make a bootable external device with a live distro (e.g. a USB stick) and keep it around. Now, if your main system ever gets messed up and can’t boot anymore, you can boot the live one and start troubleshooting.

Don’t be scared by this suggestion: getting an unbootable system is not so common, but if it happens you’ll be glad you have something ready to work on it
