Hey guys! I'm a long time Linux user and after using a work computer for the last 6 months that has windows 8.1 on it I decided I'm going to make the switch. I have my own custom rig and I would like to completely remove Ubuntu and install a copy of windows 8. I already purchased a license from Microsoft and created a bootable USB with Windows 8. I edited my mother board settings so that the USB was the high priority for booting. It booted the first time and I enterer my code. It told me to remove the flash drive and to restart the computer... It restarted as Ubuntu and not Windows though... How do I remove Ubuntu...?
