Used this https://access.redhat.com/articles/7065136 appliance to generate openshift raw image of 150GB size. Image was successfully created. Openshift version used was 4.16.16. 

During deployment of single node cluster after ```INFO Host: master-0, reached installation stage Writing image to disk: 100%``` system went for reboot and double menu entries are made to grub for "Recovery agent based installer" bcz of this system is going in to recovery mode though Openshift is installed on OS tree.   And default grub menu is set as 1. 
Following is the grub.cfg. 

`source $prefix/70_coreos-user.cfg  <--- One recover entry
if [ x$feature_timeout_style = xy ] ; then
  set timeout_style=menu
  set timeout=1
# Fallback normal timeout code in case the timeout_style feature is
# unavailable.
else
  set timeout=1
fi

# Import user defined configuration
# tracker: https://github.com/coreos/fedora-coreos-tracker/issues/805
if [ -f $prefix/user.cfg ]; then
  source $prefix/user.cfg <- Second recover entry. 
fi

blscfg`

I manually booted into OStree hence installation completed. 

```INFO Host: master-0, reached installation stage Writing image to disk: 100%
INFO cluster bootstrap did not complete
INFO Bootstrap Kube API Initialized
INFO Bootstrap configMap status is complete
INFO Bootstrap is complete
INFO cluster bootstrap is complete```

Have tried both bootloader types BIOS and UEFI.
    

  100 %  

    1. Follow the KCS to create the image
    2. install SNO 
    3. look for dual kernel entry for recovery
    

Installation fails    

 Installation should be succeeded
