As October is coming, I want to advertise Linux to people before the end of service for windows 10.
Endof10 campaign guide does not seem useful.
Is there is any good recent detailed guide to switch to Linux from Windows 10?
what exactly are you looking for? there are many guides for switching to linux, for example, arch wiki; has enough details for anybody. similarly, there are other distro wikis (fedora/debian/mint/…). But none of them are specifically for switching from windows (10). Most of them do mention that backup your stuff, or mount windows partitions for moving stuff.
If you need something to switch specifically from windows, that is hard. because the way people use windows changes a lot with people. My personal recommendation would be to just search “switch to linux” on youtube, find suitable videos (in prefered languages or target audiences, which are also suitabbly licensed(most linux youtubers release their stuff under some variation of cc, and youtube by default has also some cc license for all videos. you can check about licenses in youtube description.)). Video demos for people today or more approachable, and can also help navigate any issues that might occur during the move. Once they have some distro installed, they can look up distro wikis to build upon.
Too complex for someone that isn’t already interested. Hell, the vast majority of users couldn’t reinstall Windows if they lost the restore partition.
Maybe school them on a live USB “install”? That’s how I started oh so many years back. No risk, easy way to get comfy with a test drive. And if they like it, there’s always (?) an install button.
OTOH, dumb as it sounds, seems like most people don’t have a handy USB drive these days. At my last job, a software dev, I don’t think I talked to a single end user that had a USB available for a Windows reinstall. Weird.
I’d recommend a Debian distro. Whatever one’s preference, Debian just works and seems to have the most documentation, especially for noobs.
I tried Zorin OS with my parents who are not fimilar with Linux. Zorin seems to be close to Windows and easy enough for them.
This guide looks easy for new Linux users: https://dtptips.com/zorin-os-for-windows-users-a-complete-guide-to-installation-and-features/
