Lion re-installing on startup.

Question

Lion re-installing on startup.

Last night I installed Lion as my upgrade from Snow Leopard. Got everything working and it was great.

This morning when I restarted my Mac Pro, instead of the login window, it is re-installing Lion....to the tune of a 37 minute wait. What is the problem? Next time I restart I'm afraid it will re-install once again.

I don't think this is an update because it didn't ask me to update anything.

Mac Pro, Mac OS X (10.6.8), Quad Core, Intel Xeon

Try resetting the PRAM, Make sure the systems completely shut down first.

Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

Reboot again and see if this resolved the issue.
