When you have several operating systems (Windows, MacOS, GNU/Linux ..) installed on your computer, you may want to remove one of them.

OS-Uninstaller is a graphical tool that will let you choose the system you want to remove, and uninstall it very easily. After your confirmation, it will format the selected system, and update the bootloader so that you will still access your other remaining systems.

OS-Uninstaller also has advanced options for OS formatting, and bootloader updating.
