Free Version of Linux that uses the least resources?
Over the years, I have heard that Linux is much more efficient and requires far less RAM than windows, but it always seems to be the opposite.
I just need a version of Linux that I can practice with without reimaging my current machine.
I have a dedicated Hyper-V server for this type of stuff. Knoppix etc is ok, but I need to be able to emulate installations on Linux and to that extent Knoppix etc is not helpful.
What are some versions of Linux that are free, fast, and virtualize ok with Hyper-V?
