I am using Windows 8.1 on Dell Latitude E5420 and I am interested to give a try to Ubuntu. So to use Ubuntu efficiently, whether would I need to remove Windows and then install Ubuntu or can install Ubuntu without removing Windows so that I don't get slower performance on both OS.

I would suggest you to install ubuntu on a virtual machine and get use to it. Once you feel comfortable using ubuntu make the partition of your disk or even better reboot your computer with only ubuntu :D
