How to recover from a Kernel Panic -not syncing

Just got a" Kernel Panic -not syncing : attempted to kill init" error after I switch my selinux in enforcing mode and rebooted.

I have -573.22.1
-573.3.1
-573.1.1
-504.30.3
I tried to boot back with other old versions, but none of worked and all have "Kernel Panic", so I could not to run the sosreport from old version either. How can I recover from this?
