Upgrades often fail. Perhaps you should do a clean install of 12.04 or better 14.04 from a USB/DVD Live version

Is there something wrong with your cd?
If you want to reinstall 12.04 over the broken 14.04 then just put the 12.04 cd in and install it.

You'd have to post any particulars about your setup, like if it's a dual-boot setup or if you need help preserving your data, and so forth.
Otherwise I would consider that it is a standalone Ubuntu machine and you have backed up everything you want.

If you could give us help with what you need help with, it'll make it easier for all to advise you.

Thank you for help. I installed 12.04 LTS finally. Now I have another and serious problem. No wireless. I see only Wired and Network Proxy. Please help me to get Wireless in NETWORK. Thank you.

Thank you for help. The issue is resolved.

I have one issue in my other laptop. I have ubuntu and windows 7. Ubuntu does not show Chrome Cast there. Can I bring Chrome Cast there?
