I have a new computer. It has a 128GB SSD with Windows 10 pre-installed on it. It also has a 1TB HDD. I would like to install Ubuntu on a partition (say 100GB) on the HDD for a dual-boot. I would like to be prompted which OS I want to boot on start-up.
I have searched for this online, but everyone seems to be saying something else, from just installing Ubuntu to manually setting up partitions and adding all sorts of entries in Grub.
Are there any problems I am overlooking? What makes the tutorials diverge so much from one another?
