Yesterday I installed the latest update for OS X Lion v10.7.3 and now the system won't start - what can I do now? There are no install CD coming with Lion!

After installing the latest OSX Lion system update yesterday, my MacBook Pro wouldn't reboot. The system stops when the apple is on the screen.

Several attempt later, I tried booting in Verbose mode (command+V) and saw the same line repeat:

disk0s2: 1/0 error.

0 [Level 3] [ReadUID 0] [faclllty com.apple.system.fs] [ErrType 10] [ErrNo 5] [10Type Read] [PBlkNum 296076744] [LBlkNum 32588] [FSLogMsgID 122581959] [FSLogMsgOrder First]

0 [Level 3] [ReadUID 0] [faclllty com.apple.system.fs] [DevNode root_device] [MountPt /] [Path /private/var/db/dyld/dyld_shared_cache_xB6_64] [FSLogMsgID 122581959] [FSLogMsgOrder Last]

Starting from the network ("Option" + "R"): Doesnt' work.

Hardware test (retart computer holding the "D" key as it start up): doesn't work.

What am I suppose to do next?

MacBook Pro, Mac OS X (10.7.3)

It's not Option+r. It IS Command+r for booting into the Recovery HD partition.

Boot to the Recovery HD (cmd-r) and repair the disk.

If repairing doesn't work, try reinstalling from the Recovery HD.

Thank you guys for the recovery info (cmd-r)

However this is not working. the screen opens on the apple, and that's it.

This would probably work great for a new Mac though, but mine is a MacBook Pro (17" 2010) and I just read: "Some computers that did not ship with OS X Lion installed may have a software update available that allows them to use Lion Internet Recovery." Had I known about the firm update I would have installed it long ago, only now is a tad too late.

Any idea as to what to do next?

Try Command+Option+r when starting the system. You may have installed the firmware without knowing it as it is included in Software Update. That is unless you turned off the Auto Update feature in System Preferences or you selectively did updates when Software update comes up and omitted the firmware updates.

EDIT:

To my knowledge the Command+r feature only works to boot the Internet Recovery HD system IF there is NO Recovery HD partition on the internal drive. Otherwise that key combo boots to the R-HD partition. Which in your case isn't working.

Internet recovery is not the Recovery HD. Internet recovery is firmware that will connect to Apple's servers if it cannot find a Recovery HD. The Recovery HD is a separate partition on the Hard Drive that can be booted into. If the Recovery HD exists, it will attempt to boot to it, first.

However, if it doesn't boot to the Recovery HD, either, then your disk is likely damaged beyond repair.

Try booting from your Snow Leopard install disk. From there you may have to wipe the drive and reinstall, then restore from your backup.

... beyond repair - Ouch!

I ran a Disk Utility yesterday to diagnose and repair, and the result is that the disk appears to be OK.

Isn't it a bit too strange a coincidance that this problem occured right after the system update, until then the computer worked flawlessly.

No, often underlying problems can simply be hastened or excenuated by installing an update and can therefore be seen as coincidental. It is often the case with users who come here with disc failures. As yet yours hasn't been seen as being beyond repair though.

Good luck

Have you tried the Command+Option+r key combo yet?

Please do and post back if it takes you to the internet recovery system.

Pete could be right but I can't give up just yet I need to recover my docs.

I have indeed tried the combo: Command+Option+r unfortunately (for me) it ends up on a page with a "no access" sign. Bummer!

I have just heard of possible solution where by replacing IOStorageFamily.Key in System / Library / Extensions with one from a working mac, or from the installation disk using Pacifist (but I don't know what Pacifist is tho) this could save the trouble of reinstalling everything.

Without a backup, If it is worth it to you, a file recovery company might be able to extract the data.

If it is under warranty, Apple will replace the drive.

If not, you can replace the hard drive fairly easily. See iFixit for details.

If it is not actually the drive that is dead, but some other part that keeps you from booting, you can remove the drive and put it in an external enclosure.
