--What distro did you install?--
Nvm, I searched and it is Ubuntu 25.04 lol. I kept thinking there was a distro names "GNU Linus OS" that I never know about. So you're purely on Linux now, congrats. Was the majority of the installation time on transferring data?
Ubuntu is a great distro, everything should work till forever if you dont mess around with system configs. Even if you like to tinker with system, Linux is easier to fix than Windows. Command lines can be scary at first but they really help.
