How to uninstall Windows 8?

I do not want to dual-boot, I want my PC to solely run Ubuntu. How can I do this? I've tried everything and it just won't work.

I am currently running Windows 8 and want to run Ubuntu 12.10. I've tried to install and run GParted, and it won't run. I've also tried uninstalling Ubuntu (actually, I restored my system to default, since I have all my files backed up on my server) and then loading it via USB. I'm at my wits end here! Please help.


You don't need to "uninstall" Windows.

I assume you're installing Ubuntu using a USB stick.

  1. Boot off of the stick, and when it presents this screen:

  2. Select the Install Ubuntu option. Then, in the partitioning step:

  3. Select the option to Replace Windows with Ubuntu. The Ubuntu installer will then overwrite your Windows installation, and set up Ubuntu's bootloader (GRUB) to boot into Ubuntu.
