I m completely new to all of this... I just want to install ubuntu because it is suppose to get rid of most of the virus problems, so anyway I was following online instructions to install ubuntu alongside windows 7 these are my laptop specifications. I tried booting with a pendrive using netbootin and other similar program but once I boot the laptop in ubuntu I click try without installing button and go to desktop then my mouse stops working. What am I supposed to do or what am I doing wrong?? Also please suggest a thread for proper installation of ubuntu alongside Windows 7. Thank you.
