[RESOLVED]Unable to perform un-attend installation using customized bootable iso file

Latest response

I followed the steps from this link How to create a minimal bootable media with Kickstart file in it for Red Hat Enterprise Linux 6? on test machine and could not get it done successfully. With the customized bootable image, i could get the first graphical screen, after which I hit enter key to install, it prompts back with option to select keyboard, so it is not reading the answer stored in "ks.cfg" which is built in the bootable image file.

Here is what my ks.cfg file looks:

##Disabling NetworkManager
%post
for nic in $(grep -l NM_CONTROLLED.*yes /etc/sysconfig/network-scripts/ifcfg-*) 
do
sed -i 's/NM_CONTROLLED=.*/NM_CONTROLLED=\"no\"/' $nic
done

/usr/bin/yum remove NetworkManager -y 2>&1 > /dev/null
%end

Everything looks good and no error in the process, but booting a new vm with the image file doesn't perform automated instillation, it prompts for user input.

Initially, i tried this on RHEL6.7, i mean created "linuxboot.iso" file and tested which failed to perform un-attend installation. I tried all these steps by downloading rhel 6.5 boot image and no success either.

I also tried to create boot image with kickstart file integrated using the "isolinux" files found within the installation ISO image, but no luck. Unable to make this un-attended installation.
