I have done some research myself, but I have not gotten much information regarding my questions. I want to start using Linux. What are some tools to learn Linux? How powerful does a machine have to be to run Linux? Can you switch to Linux Distro when you have a Windows OS (and if so, how can you do it)? What is a recommended Linux Distro for a beginner? I am planning on putting Linux on one of my old PCs, and I am not sure if it can handle Linux. Spoiler: PC Specs Intel Core 2 Duo E7500 @2.93 GHz 10 GB of RAM 64-bit Windows 7 149 GB hard drive (w/ 1.31 GB free) Not sure if this is in the correct section or not.
