Newbie, trying to learn Linux
My background is biology and not experienced at all with anything related to coding or programming, but just beginning. I have recently partitioned my old pc (with windows Vista) and installed CentOS Linux 7. I am trying to learn Linux. For a beginner, I have a problem and a question.
Problem: I cannot get windows anymore on the computer. How do I check if I have overwritten Vista with CentOS?
Question: How do I connect to internet using CentOS?
