I don't know what distro you're installing or what the hell you're doing, but most of the time it's trivial. From my experience, the Linux installation is much simpler and easier than Windows.
It is different though, so if you bash your head against it expecting Windows then you're obviously going to have a bad time. You need to start with the understanding that it's a different thing and you'll have to learn it, just like you did Windows when you first started with that. You weren't instantly an expert. You just forgot what it was like to be a noob who doesn't know what they're doing.
