'''NOTE:''' You will need an ISO file for CentOS 7 (the same one you burned your DVD from). It is recommended to use the command:<br> '''<span style="text-decoration:none;color:blue;">wget http://mirror.senecacollege.ca/centos/7.45.17081804/isos/x86_64/CentOS-7-x86_64-DVD-17081804.iso</span>'''<br>to download this image onto your host machine. In this way, you can keep it on your host machine for the remainder of this course in case you need it.
