Mountain Lion 10.8.2 Will not Boot

I'm on an early 2011 MBP. I have a 256GB SSD with OSX on it and a 500GB HDD with a data partition and a boot camp partition. I just updated from 10.8.1 to 10.8.2.
When the I turn it on, the start progress indicator fills up then the machine turns off. Booting to safe mode also fails. When I boot to the terminal, that works, in that I get the terminal with no errors, though it says the disk isn't writeable.
When I boot to recovery, I can only "verify disk" - the other 3 options under first aid are unavailable. When I attempt to reinstall, the SSD doesn't even show up as an option - just shows the recovery partition, boot camp partition, and data partition.
My most recent time machine back up is rather old as I haven't been working from the desk where I have my backup drive hooked up, so that's not a favorable option at this point.

Hi all,
I see its been 2 months since the last post. Did someone find the solution? I have the same problem with 10.8.2 update. Macbook pro mid 2010 with Crucial 256 m4 ssd (latest firmware 010G). Since yesterday my mac refuses to start.
What I did so far:
1. Impossible to start os x 10.8.2, stuck at spinning circle below the apple logo at startup. Disk check ok, permissions ok. Startup in "safe mode" stucks on spinning  wheel as well.
2. Impossible to format the drive for a new clean install. What I find strange is that I cannot format the ssd with any utility. So far I tried with windows, linux and with disk utility on os x. I put the ssd in a usb casing and I am able to read it as an external drive, can copy some smaller files from it but cannot change anything on it (no permissions).
3. Did a clean install on original hd of my mac. Data transfer (1 user)  from time machine or the ssd goes through 85-95% then stops. And now impossible to format the original drive with the 10.8.2 installed to downgrade to 10.7.
4. Pram reset
Does anyone have any idea what to do now?
Thanks!

    Word, Powerpoint, Excel - none of them work. . . . Any ideas?

    You can also try Pages for Word / Numbers for Excel. Both can import/export Word and Excel files.

  • Mountain Lion Mail - bin items will not delete

    I use Mountain Lion Mail and use Google IMAP.  In mail box behaviours I have it set to Trash-> move deleted messages to the trash mailbox.  The items go the bin.  However when I got to Mailbox-> Erase deleted items nothing happens.  In Gmail I have it set to delete immediately.  But nothing seems to work in Mail.  I have 16,389 message in the bin!!!! How do I delete these messages rather than going in one by one? Trash under the Top right hand heading of Mailboxes does delete it is just the bin that does not erase any emails.  IMAP in Gmail is set to Auto-Expunge On - Immediately update the server (default). Do I have a setting wrong somewhere?

    Try reinstalling Mountain Lion:
    Reinstalling Lion/Mountain Lion Without Erasing the Drive
    Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
    When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
    Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

  • Brand new iMAC, Mountain Lion installed, dashboard widgets will not download. Webpage times out. Any suggestions?

    Just purchased a brand new iMAC and sucessfully performed download and install of Mountain Lion (free upgrade). Discovered that dashboard widgets will not download as webpage times_out in both Safari and Firefox. Already set security to allow downloads from 'anywhere' but with no change. Downloads from anywhere else works fine, just widgets won't work, and I've been trying for several days now. Any suggestions? (firewall is off).

  • I upgraded to Mountain Lion, now photoshop CS5 will not open

    I order photo prints using one of the Roes software programs.  I needed to update Java to 7, and to Mountain Lion and now neither the Roes or Photoshop CS5 will open. 

    These are the versions of iPhoto that are and are not compatible with Mavericks:
    What version of iPhoto are you running?  What happens when you try to launch iPhoto?  Any message?

  • My macbook pro has mountain lion installed and it will not play dvds

    my hubby's macbook pro has mountain lion installed, and will not play dvd's.  It says it is unsupported, I also have a macbook pro but has snow leopard on it, mine will play dvd's.  Please help me, I can't figure out why his won't play the same dvd's as mine.

    The most frequent problem in an optical drive is a dirty lens.  Use a lens cleaning DVD, a few shots of compressed air in the slot or a fine microfiber cloth (eyeglass lens cloth) wrapped around a business card and gently inserted inside the slot.  If no success, the Apple store genius bar is the next stop.

  • Mountain Lion was reedemed but will not download

    I just received my emails from Apple with the redemption codes, etc.  Received the link to download Mountain Lion in my app store.  It says "downloading" in the Launch Pad, but in the App Store when I click OS X Mountain it says -  "The item you've requested is not currently available in the U.S. store."
    Across from that seemlingly deadlink for Mountain Lion is the button "Download"  When I click it nothing happens and "download" just lights up again.
    Is it downloading properly since it says "downloading..." on my Launch Pad?  Is there any way for me to see how much time remains on the download? 
    Please Help.
    (I am currently running on OS X Lion and just upgrading)
    Thank you!!!

    Thank you,  Stupid me didnt realize Mavericks was free.  I am downloading Mavericks now.  I deleted ML from my purchases on the AppStore. 
    Is there a way to delete it from my Launch Pad before it has downloaded since I obviously will not be using it now?  Didnt realize Mavericks was free.  I cannot believe I paid 20 dollars for ML.
    I feel cheated.

  • After upgrading to Mountain Lion the mail app will not quit and then freezes only a force quit will work. How do i quit it normaly?

    Mail will not quit normaly only force quit works. Any help?

    Under the Mailbox drop down it is the last option.  Just select a mailbox first before going to the Mailbox menu.

  • HT202159 I have purchased Mountain Lion today and it will not download properly, it just quits. Advice please!!

    Thanks

    Check your connection speed. Ideally you will need a connection of more than 15Mb/s. Else it would time out before it complete the download.

  • IMac 27 inch i7 OSX Lion will not boot up from Hard Disc

    iMac 27 inch i7 OSX Lion will not boot up from Hard Disc on cold start, and cannot find wifi hardware in the machine.   Restart and everything is fine.   I have two machine and they behave the same.   Software or hardware problem?

    First of all, try a hard restart; making sure no disks are in the slot, unplug everything from your computer (keyboards, mice, etc.) and then unplug the computer itself. Leave it unplugged for a minute or two, then plug it back in and boot it up.
    If that fails, reboot it while holding down the option-key on your keyboard. The screen should show a choice of which disk drive to boot from. Choose your usual drive.
    If that fails, reboot it while holding down the shift-key on your keyboard. It should take a while for it to boot up, as it is destroying all connections to sources that may contain a virus.
    If that fails, reboot it while holding down keys "option-command-P-R" until you hear the startup tone a second time.
    If that fails, reboot it while holding down the C-key. Make sure you have inserted the installation disk before doing this step.
    If that fails, reboot it while holding down the command-key and the R-key.
    If that fails, please reply to this and let me know.

    my macbook pro running lion will not boot . it stays on the grey page with the cog spinning. I have tried all methods of booting to no avail. I have removed the bottom and taken out the battery and the ram . will this affect my applecare warranty. I had to try myself as I'm overseas for two months and nowhere near any sort of help .

    there was a recent software update that seemed to screw HDV up.  Do some searching here over the last month or 2 and you'll find a bunch of posts and some possible solutions.
    Worst case scenario, do as Shane suggests.  But might I suggest you take a look at the user tips section of the forum.  there are some great tips on how to prevent these sorts of problems by cloning your startup drive, etc.
