I have created custom ISO image from “Rocky-8.7-x86\_64-minimal.iso” using  
“mkksiso /root/anaconda-ks1.cfg /root/Rocky-8.7-x86\_64-boot.iso /root/Rocky-8.7-x86\_64-test.iso”

When I try to setup machine from my custom ISO image using .ks(kick start config file) .  
All the ‘OS’ configurations are setting up properly and machine is going for reboot. But after the reboot again it is reinstalling ‘OS’ and rebooting and continues to reboot.
