# Download and burn on a DVD a copy of the Centos 7 installation DVD (64 bit edition) from the Centos web site or the Belmont server.<br>'''Note:''' we'll be using the 64 bit version of Centos because all of our lab computers are equiped with Intel 64 bit mainboards and CPUs, and any computer you bought in the last few years for yourself will be 64bit as well.
#* '''Seneca's mirror of Centos:''' http://belmont.senecacollege.ca/pub/centos/7.2.1511/isos/x86_64/CentOS-7-x86_64-DVD-1511.iso<br>This is very fast, but is only accessible from within Seneca's network - you can't access this from home. You can burn this disc on the machines in the Open Lab.)<br>
#* '''Outside Seneca College link (available from any Internet connection):<br>''' http://archive.kernel.org/centos-vault/7.2.1511/isos/x86_64/CentOS-7-x86_64-DVD-1511.iso<br />
# Insert your removable harddrive into the machine and boot from the DVD.
{{Admon/tip |Boot order|Some of our machines' boot order is configured to be Harddrive first, DVD second. Which means you won't be able to boot from the DVD if you already have an operating system installed on your drive.}}
'''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://belmont.senecacollege.ca/pub/centos/7.2.1511/isos/x86_64/CentOS-7-x86_64-DVD-1511.iso</span>''' to download this image onto your host machine.<br>In this way, you can keep it on your host machine for the remainder of this course in case you need it.
