I have a somewhat old laptop (Dell Inspiron 3541) with Windows 10 installed. Through Live Mode, I've tested that it works with Ubuntu 16.04 (doesn't fully work with 18.04).
After facing some issues with Windows 10, I'd like to install Ubuntu in dual-boot with Windows 10, although I would also like it to not be visible on a normal boot. I'd like to only show that Ubuntu is installed when a key is pressed at boot time (like SHIFT to show GRUB).
Is this possible? If so, how?
/etc/default/grub
