I have a 128GB SSD with Windows 10 installed on it and I also have a 1TB HDD on my computer. I want to dual boot Ubuntu along side with windows 10 but I don't know how much space I need to give to Ubuntu and if I should even install it on the same drive as windows, because I roughly have 60GB's on my SSD left but I thought it would be better to keep them like that since windows always has updates and that sort of stuff. I mainly use windows for gaming and pretty much everything, Ubuntu is for college programming purposes.
Sorry if I misnamed any term but I'm still a beginner to all this sort of stuff.
