Hi, I am trying to install ubuntu(7or higher) over network without using official ubuntu mirror rather i want to install it from my mounted iso image(install cd) using PXE net booting from my local server.I got success to do it in ubuntu 5.1 disros which is having netbbot option under its install directory but it is missing in higher versions(7 or higher) for that i downloaded netboot.tar.gz file and it is helping me to boot over the network.But when i am manually giving my repository path during installation it is giving errors and stop the installation process.error was something like bad repo addr or addr not valid,release file missing. But the same process was working fine with ubuntu 5.1 distro. I am using dhcp3 server,tftp-hpa for tftp and apache2 for http access. So,if anybody knows how to do that one plz help me. Thanks & regards. S.Pahari
