Hello, people. I just made a mistake I'm really hoping there's an easy way to fix it.
So I just started dual-booting.
In an attempt to make the GRUB boot menu dissapear and just boot Ubuntu everytime (Since now I got 2 boot screen everytime I turn on the machine. 1 from Windows, and then after I choose Ubuntu, the GRUB) I used the Grub Costumizer and uncheck all boxes. Now GRUB still appears, and but there's no choice at all and I can't boot Ubuntu.
So does anybody know how I can fix this? Any answer would be most appreciated.
Thank You anyway.
