God i wish. And most everyone here could install a new operating system in about 20 minutes. But nobody else is going to because the learning curve for a regular user to install an os is basically perpendicular. Even if they had a linux installer already on a flash drive.
Oh just boot into the bios and find the option to boot for a flash drive and then boom installed.
Which requires a user to know, What a bios is
What booting means
What boot options mean
What the model of their flash drive is
What button on their keyboard they need to press to get to the bios
What secure boot is
Where they need to go to turn off secure boot
How and where to back up their important files
What a disk partition is
How to reverse the changes made to the bios so that it doesn’t boot to usb by default.
And that’s assuming they know why they want a different OS, why they care and that they know about Linux in the first place.
Most people dont and never will. All you can do is install Linux for the ones you like the most and say a prayer to your favorite deity for the rest.
