El Capitan installation worked but my first login always..

[x130844]

shows the following, which I am not sure why, as I was running 10.10.4 nicely before updating to El Capitan.
Do note that I don't have the dmg file as indicated.. How can I clear this? is this a tmp file somewhere? or a plist? or a crash when I reboot?

El Capitan installation worked but my first login always.. -fixed it-

ok, i figured it out, my nvram was getting in the way
I deleted the clover emunvram whatever and it now boots with no KP
I hope it won't impact other things, but so far so good.
