I installed 12.04 about 3 days ago. I was not very happy with the results, when I start, it takes a lot of time. I have also display problems. For example, the movement of windows, the selection box, the movement of mouse pointer.
My colleague who recommended me to install Ubuntu told me that it requires many fewer requirements than Windows (XP in my case).
But anyway, when I installed Ubuntu, I installed it with the first option of the installer. I think that option says, "install Ubuntu, but keep Windows" or something, and asked me to allocate an amount of storage on my hard drive for each OS. I allocated 247 GB for Windows and 80 GB for Ubuntu.
I want to know if I can uninstall Ubuntu, and get back the storage allocated to it, return to Windows, along with those 80 GB, or just help me with these display issues.
I hope you understand me, I need help fast.
