something is going on with your launch daemons. When you're getting stuck on that gray screen, that's the part of the startup process when the mac is loading the firmware needed to boot. If it's not going past that, they may be corrupted, or the computer for whatever reason is just not able to find them. Have you been able to get into safe mode at all? Have you recently installed anything 3rd party? (software or hardware). Worst case, you may just need to reinstall the OS from recovery

I would recommend resetting the SMC and the PRAM on your MacBook Pro:
- Shut down your Mac.
- Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
- 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.
Resetting the System Management Controller (SMC)
- Shut down the computer.
- Disconnect the MagSafe power adapter from the computer, if it's connected.
- Remove the battery.
- Press and hold the power button for 5 seconds.
- Release the power button.
- Reconnect the battery and MagSafe power adapter.
- Press the power button to turn on the computer.
Hope this helps

I should have mentioned that I also tried to boot in safe mode several times.
It always gets stuck with the progress bar at about 25% progress.
I don't know how I can boot safe and verbose mode at the same time,
but feel that the process stops at the same time.
I did manage to get to the login screen a couple of random times, and I also tried to log in the guest account to see if by chance something was related to my own account, but the process got stuck with the guest account too.
I have reset the PRAM and SMC. In my case the battery is built in, so I followed the instructions for those MBPs
and believe the reset worked because my chime got louder after I did the procedure.
The one other clue I can see while booting is this message:
unable to read /var/db/bootcahce.playlist : 2 no such file or directory
and sometimes two more messages for missing files in
I'm ok reinstalling ML from the recovery partition but worry a bit about missing my last few days of backup.
Are my files supposed to be safe in this process???
Thanks for your help

sorry should have type it more precisely
unable to read /var/db/BootCache.playlist : 2 no such file or directory
file names are case sensitive...
Nevertheless my main concern at the moment is whether reinstalling ML from recovery is not going to affect my files, which I have not been able to back up (about one week of data). Otherwise I fear my only option is to extract the HD (or boot in target disk mode) clone it, and then run the process knowing I have the original somewhere else.

Backing up through CCC...another 6 hours left. Had to use an older mac with USB 2.0 which is probably the bottleneck, since it's going at about 2 min per GB. The new mac (the one with the problem) is in target mode through firewire. The good news is that I can access all my files, which has allowed me to do something useful while the cloning process is ongoing.
Once the clone is over, I'll get on reinstalling ML - probably good because it is a system that had lived thorugh many upgrades (I believe all the way back to tiger).
Q: is there any benefit reinstalling ML from the original disk or from the recovery partition??
