Ubuntu has done a decent job for normal installs but take it from me, if you want to dual boot it, it still doesn’t make it easy. It’s too easy to mess up your whole system if you don’t know what you’re doing, not to mention bootloaders are all still stuck in the 90’s, and are even worse to configure nicely than they are to use.

Dual booting is one of the best ways to introduce someone to Linux in theory as they’ll feel safe trying that without having to delete their whole old system… except it’s also the scariest and most difficult way to install it and no installer makes it easy. It’s a real foot gun.
