RAM size minimum required for Dual booting windows 10 and ubuntu 18.04

Question

I have a hp laptop and its specifications are 4GB RAM and AMD A8 processor.Is it preferable to dual boot it with windows 10 and ubuntu

Answer 1

With dual-booting, the two OS's are not running at the same time, so RAM is not a factor, as long as you have enough to run one OS at a time. Ubuntu and Windows 10 need 2GB, so you're good to go.

Though if you do want to run both OS's at a time, you could run one inside the other on a virtual machine (e.g. using VirtualBox).
