Getting familiar with the CLI will save you a lot of issues but I understand the apprehension. When learning DOS 30-odd years ago and going through the commands in alphabetical order, I came to “format” (I don’t know how I got past “fdisk") I typed in “format C:” When asked if I was sure, I said hell yeah I’m sure and hit “Y” and [return].

I’ve not been apprehensive of breaking things since. ;) That was on the *only* computer in the house at the time and contained all my dad’s Quicken information. Thankfully, he had a backup.
