i came across this guys post and he had the same problem as me
"After downloading the 10.7.3 Lion update today, I noticed that the installation was stuck at 'Moving items...' at the very end of the process. I panicked slightly and shut my mac down thinking it would just re-boot back in to 10.7.2 with no issues.
But the douche that I am, I've caused my mac to just grey screen at every attempt to start it up. I've tried repair disk and disk permission through Recovery HD and I've tried a Safe Boot as well, both have done nothing.
can anyone help us out, i have no backup and the reinstall lion option dosent work for me :/
