I've read that it can be dangerous for your computer to try to run Ubuntu and that the safest option is to run it on an external hard drive. Is this true?
(I don't want to run it through a Virtual Machine.) I would prefer to dual boot it, given that my hard drive has so much space.
Update: So does this mean that even if I have Ubuntu installed, that my data would still be at risk due to, say, stability issues?
