I have configured PXE booting for auto installing ubuntu. I have added the url of pressed file in preseed/url section of default file in /var/lib/tftpboot/pxeconfig.cfg. but i have a problem that when client is booting with PXE, it doesn't use preseed file during loading initrd and kernel. and normal install is loaded and ask me to answers the questions of installing.
Could anyone help me??
