I've installed Ubuntu 16.04 on a machine that already had Windows 10 installed, I believe installed in UEFI mode. Upon installing Ubuntu I came across the option to disable secure boot, I didn't do so because I wasn't sure what it would do. After installation finished, the system just boots to Windows directly without showing the GRUB menu. Is there any solution to this?
I have a single partition dedicated to Windows that I shrinked, alongside the system and windows recovery partitions.
The laptop is an Acer.
