Win 8 - Ubuntu

I want to completely remove win 8 and install ubuntu. However i cant find any help online. I am hoping someone here could help me.

When you install Ubuntu, the installer will give you options to replace Windows entirely, or dual boot


I am going to do that now

I bought a laptop and wiped Windows 8 for Ubuntu. If you run in to any problems ask. UEFI can be confusing to someone who has never messed with it.
