view story

http://www.linuxquestions.org – I would like to install centos through kickstart method. I had dhcp configured in my server system, and mounted the cd to the html folder, but when i am giving the kickstart file link in boot menu to the client system, it says installation tree not found. When i am giving the mounted cd link of centos in html folder link it starts the installation and asks normally. So what should i do to start kickstart installation? (HowTos)
