In this video I will be showing you how you can remove the 'Error: diskfilter writes are not supported. Press any key to continue' error in Ubuntu 14.04 which you see when you boot up.
The commands are as follows:
sudo nano /etc/grub.d/10_linux
Find the line which says quick_boot and change it from 1 to 0. Once you have done this, save the file and exit. You can then run the following command
If you now reboot your machine, you should no longer see the error anymore.
