So, i have been using ubuntu for over a week now and i have managed to mess it up and had to reinstall it twice. the first because the updater wouldn't update any more and the second because i could fix a xserver issue. the last install, all i did was reboot and it messed up. i am just wondering if this is cause i am doing something wrong? or is ubuntu not great for beginners such as me? i switched over from windows vista and i love linux except for how fragile ubuntu seems to be? can i make more durable, so i am less likely to have to keep reinstalling due to messing up something? i really don't want to go back to windows. any helps or tips for a complete noobie would be great!
