Hi tomlaino,
Mostly
kickstart(unattended operating system installation) files are used for Network based Installations like PXE booting.
You can find more info about kickstart
here
Please check your boot order(or priority) in your
BIOS.
If your Dell system is having "
Network Booting" as first option. Change it to "
CD-ROM or DVD-ROM" and try.
