Next, you will need to run GParted and delete the NTFS Windows partition and you can extend your Linux partition selecting resize the GParted application and finally you can exit GParted.

Now run your Linux File manager and go into the root system or computer location and search the boot folder and it will ask you to enter the Root admin password for your Linux OS after that you can delete your Microsoft folder inside the boot folder and if you have installed grub2win on your Windows OS you will have to delete that folder also and leave everything else as it is and exit the Linux file manager.
