Ubuntu not booting from USB; No "continue" option in the installer when choosing to install alongside Windows

Question

I have windows 8.1 installed on my laptop. I have burned Ubuntu 14.04.1 to USB. But when I restart my laptop & go to boot menu Ubuntu cannot boot from USB. I have done separate partition of 20 GB. Please help me to install from USB. I have also tried Wubi for 12.04 but it gives an error. I want to install Ubuntu alongside Windows with dual boot.

Update

I have done booting from USB helping with answers. and now on installation step, when I choice "Install Ubuntu alongside Windows 8", I have no "Continue" option button to continue installation.

Here is the screenshot of this step:

With windows 8 in addition to changing you boot order in your bios you must disable secure boot and OS Mode Selection (both in your bios) for it to recognize Ubuntu.
