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.
