I have a laptop on which I have three OSs, Antergos, Windows 10 and Ubuntu. I installed the Ubuntu long after I had the Antergos on the system, so since I installed the Ubuntu, my laptop uses Grub in the Ubuntu installation.
That was no problem, but now I want to remove the Ubuntu installation so I can use that disk space for storage. I’m pretty sure that if I just reformat the partition that the Ubuntu is on, I won’t be able to boot my machine. What should I do so that my machine boots from the Grub on the previously installed Antergos installation.
I’ve attached a screenshot of my SSD configuration as shown by gparted.
I’m not sure what sda1 is. Desconhecido=unkown
sda2 is the Windows.
sda3 is the Antergos
sda6 is just for storage (armazem)
sda7 is the Ubuntu
