@ tascoast - using a presentation very much like the gif you made, playing during the install or just before or after the install, for example would be nice.
But, once again, most (new) users that need a slideshow/ quick start file probably won't be thinking about Grub recovery... Maybe starting with something more basic like (in no particular order):
1- how to use the menu and how to find applications (and help knowing what the main apps do)
2- clicking Firefox to get on-line (some very basic windows users don't even know that any other browsers exist for a PC, other than the ones that come pre installed on Windows...) also how to connect to a WiFi network
3- using the file explorer to access and use music and video files (referring to VLC as the default media player)
4- same for office files (warning about very good but not full compatibility with MS Office products- it's not the scope of a quick start but you can mention MS Office on-line [ I did a how to over here:
https://forum.mxlinux.org/viewtopic.php ... ce#p462125 ]. At least it has the exact User Interface new users are used to. Not for a Quick Start but handy for newbie users- a quick explanation somewhere on the Libreoffice MX menu about how to change the UI to the "ribbon" most new MS office people are now used to and love)
5- Once again, one of the complains people talk about on-line: software compatibility, in particular Games - show the games that come preinstalled - Solitaire is probably the most used computer game ever and a version of it comes with MX- and of course Steam and how to enable Proton for all games (that's complicated because Valve could change that any time)
Then Troubleshooting: installing drivers, helping with grub problems, how to create and use backups, help with dual boot- once again that's a though one- most people think that computers have only 2 operating systems, Windows for "PC's" and Mac OS for "Macs". And their minds would be blown by the idea that they can have multiple OS boot options...)
A bit off topic: I'm trying to recall why did I begin trying new OS other than Ms's... And apply that to new users. I believe that I grew more worried about using pirated software and began using free and legal OS's and Office suits. Most people don't worry about that because:
1.1- most desktops and laptops already come with a legal (and "Free", because it's already included on the cost people pay) Ms Windows OS, and
1.2- MS windows "new" tactic of first offering their W10 as a free upgrade and later of offering it as a kind of "Freeware"- WinRar style- people can download, install and use it for free without activating it and have basically no other problem than a polite warning on the lower right side of the screen (but still it's a non compliance of it's terms of use).
2- most people don't really care about the legality of what's on their computers.
So I guess there are only a few kinds of users a Linux OS can appeal to: (idealist) people worried about being spied by big companies like MS and Google; tech geeks; people with older hardware that does not play well with other OS; curious people that like to try new stuff or have a system than they can run from a USB stick in case their main system crashes (hey I'm included on all these categories)
