Been in windows for years, but started to like Ubuntu recently. really wants to install ubuntu alongside with my windows (just in case I need to do job quickly as I'm new in ubuntu and in case I dislike Ubuntu), so I'm looking for way to install it alongside the windows and at the same time also looking for "how to" uninstall ubuntu. BTW, I have preinstalled windows on my laptop (HP ProBook 4331s) and wonder will it be okay to install ubuntu side-by-side??
