From http://support.apple.com/kb/ht1564
(Mac OS X: What is Safe Boot, Safe Mode?)

"Mac OS X v10.5.6 or later: A Safe Boot deletes the dynamic loader shared cache at (/var/db/dyld/). A cache with issues may cause a blue screen on startup, particularly after a Software Update. Restarting normally recreates this cache."

=====-----=====

From http://support.apple.com/kb/ht1455
(Mac OS X: Starting up in Safe Mode)

"To start up into Safe Mode (to Safe Boot), do this:
1. Be sure your Mac is shut down.
2. Press the power button.
3. Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
4. Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear)."

I had a similar problem with Lion DP1. I erased the HD with Apples Disk Utility and reinstalled Lion DP1. However, the safe boot works usually in the final versions of Mac OS X.

Can you get into the recovery partition ( command-r ) ?

During a verbose boot does it hang on the same thing each time?

Mine did the same thing. Both preview versions.

I would restart, blue hang, then restart with SHIFT and it would start normally. Restart again, 50% of time it would hang at blue screen.

Verbose did not help as the screen mine hung at was after OS X stops loading scrolling text, so could not see where it would stop (looking for 'we're hanging here...' message).

Finally gave up on Lion yesterday and went back to SL. Not worth trouble. Reported a bunch of stuff so I did my developer thing, now I'll just wait it out until release is near.
