How to Remove Ubuntu from a Dual-Boot with Windows (for UEFI BIOSes)

In this video, I show you how to remove Ubuntu from a dual-boot with Windows on a UEFI BIOS.

Disclaimer: While the odds are extremely low, there is a very small chance that resizing partitions will cause data loss. Because of this, it's a good idea to make a backup of your data beforehand. I WILL NOT BE RESPONSIBLE FOR ANY DATA LOSS THAT MAY OCCUR BY FOLLOWING THIS GUIDE! Also, deleting your Ubuntu partition will delete any data that is on it. So be sure to have your data migrated to your Windows partition BEFORE doing this!
