Need to install 14.04 from DVD

[mslinux2]

My upgrade from 12.04 to 14.04 has resulted in problems with internet connectivity and non-responsive mouse and touchpad. I think I will need to do a fresh install from DVD as I cannot connect to the internet. With a troubled upgrade in place, what is the process to install from DVD? Should I go from 14.04 to 14.10?

Should I go from 14.04 to 14.10?

No. Use something known to be stable. 14.10 has been released for about a week and is wet behind the ears. Besides, 14.04 LTS has five years support while 14.10 has nine months.

Boot from the DVD, Try Ubuntu, open Gparted and take a screenshot of the drive you have 14.04 installed on. Post it back here, please (attach it using 'Go Advanced' or Adv Reply' and the paperclip icon).

Also, what are your computer specs (cpu, ram, graphics)?
