This is a Gparted screenshot of my hard disk:
/dev/sda5 are Windows and
/dev/sda7 has Ubuntu. I would like to uninstall the complete Windows partition and install Lubuntu on that.
I am scared that when I delete the Windows partition I will lose the grub and won't be able to load Ubunutu again.
Can you please guide me with safe steps to uninstall Windows and put Lubuntu there.
