I have had Ubuntu installed as a dual boot on my Windows 7 computer for about a year now, and haven't done anything with it due to my inexperience, and the extremely slow speed of Ubuntu, even with updating. I had posted on here before about what the problem might be and the one most people settled on was the fact that it was encrypted. So, now I ask for help with another thing. I need assistance maintaining the existing partition on my hard drive for Ubuntu (and the Windows one obv as well), uninstalling Ubuntu, and then reinstalling it all without removing the Gnome boot select screen. Can you guys help me please?
In addition, as a CSE major at my college, I notice that the computers in the labs are running Ubuntu, also motivating me to install it on my computer, to ease the transition between homework and school work. Can someone point me in the direction of some good tutorials or programs so I can get better acquainted with Ubuntu?
