So im trying to install ubuntu to dual boot windows 8.1 on my hp pavilion. It came pre installed with windows 8.1. Before i get started here please note:

I have tried with legacy mode on/off

I have tried it with secure boot on/off

Fast boot on/off

All combos of the above

Using Lili to burn the usb

Using Universal USB Installer

Just booting from the iso file

Yelling at the computer

Im using a live USB to boot into the ubuntu installer and do all that stuff but every time i try booting the usb it says "Unable to boot from the selected usb device". What am i doing wrong and how to do it right or should i just throw away windows 8.1 all together.

Also:
Im trying to use ubuntu 14.04

Boot windows and go to control panel and find the fast boot option turn it off (dont have win 8 too find it so have a good look)

Next in bios make your settings like this

> Advanced: Fast bios mode to disabled  

> Boot: Secure Boot to Disabled

> Boot: OS Mode Select left at UEFI OS (To allow Windows alongside)

> Boot: Boot device priority -> set USB HDD at top

Now your PC will auto boot from the USB (if it is inserted) when you reboot or it will run boot loader if not inserted.

Here you can find a very detailed guide all about linux and UEFI
