You might have been unlucky. I never had serious installation issues when installing Ubuntu on a lot of different computers in the past five years. Just started the installer, click next a few times and reboot into the new installation. It used to be some tinkering required to get everything to work, but apart from having to enable the proprietary Nvidia driver in a GUI (and having to search for it) everything else just worked. My last Windows install however was a shitshow. Took ages and I had to disable a ton of surveillance stuff. On top of that I had to go through some weird hoops to keep the thing from requiring me to create a Microsoft account. What distro did you use? I guess some are more difficult than others
