Solution

for the wireless you have, it's

Broadcom BCM43142 802.11b/g/n

You might need to install the proprietary driver for it.

Please connect to the Internet by using the Ethernet port (for download the driver), and open your dash, search for "driver, you will see a tool for this:

Select the driver, press "apply changes"

It should do the trick. (Although this is demoed on 14.04, it could apply to 12.04 too)

How did you get ubuntu to boot after installation? I tried several fixes found in the forums and was unsuccessful every time. I have tried Ubuntu 12-15, Mint 13-15, and even Kbuntu 14-15, and while they will all install none are able to boot once installed, they get stuck at "recovery" in the bios. And yes, UEFI is fully enabled.

I didnt manage to boot after installing until i completely removed windows. It seems window will take precedence, ruining dual boot
