Somehow in your Windows/Boot Camp adventure you have clobbered your partition map. You should be able to boot from the network provided you have a network connection via Ethernet.
To start reboot the computer and at the chime press and hold down COMMAND-OPTION-R keys until you see a globe near the top of the screen. This might take 15 to 20 minutes so be patient. After the globe appears wait for the Recovery HD screen to appear. From this point it's much like you were using your own Recovery HD. Do the following:
Drive Partition and Format
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
7. Upon completion quit DU and return to the main menu.
8. Select Reinstall OS X from the main menu and click on the Continue button. Be sure you select the correct drive on which to install OS X.

Following an automatic update, the machine wouldn't boot. Screen came on (shows white) - then either showed a 'No-Entry' Sign and a spinning cog, or a folder with a qusetion mark. I tried to start the machine in different modes ( eg. holding shift after the tone ) but nothing worked. after leaving the machine alone for 1 hour. It worked perfectly again. I did a 'verify disk' check which found no problems. 2 hours later it then froze ( In - Photoshop). Could not force quit, so shut down, and have not been able to boot again since (white lit screen - flashing folder with question mark) . I have also taken the hard drive out and checked the connections which seem fine. Any suggestions? - Is the Hard Drive dead. : other info : It was also running parallels 8, with Windows 7. at the time of the update....

I have a MacBook Pro bought in dec 2009. Currently has mountain lion osx installed. Worked like a dream until today. Randomly froze, so I restarted it. To find I got a grey screen. It wouldn't start. Also note my DVD drive doesn't work, but mountain lion was installed via App Store anyway.
So here's what I done so far:
tried resetting PRAM - No success
Done disk utility. Disk verified with no errors. I even re formatted disk. - no success starting.
Tried re installing mountain lion via download . It froze halfway installing -no success.
Tried backing up a time machine backup from my USB hard drive. It froze at 1% - no success
Tried booting from safe mode - no success
Tried the command line boot - no success.
Please someone help!Sounds like the hard dre has left the building, Died, in the Sh*tter, Gone to the hard drive resting place in the sky.
Buy a new drive connect it to the system with a SATA to USB adapter and see if you can install Mt Lion on that drive connected externally. If you can then the drive inside your system has failed.
Oh Wait!!!! You have the 2009 model. They are known for bad drive to logic board cables. So it may not be the drive itself but the cable going from the drive to the logic board. Do the same as above then if the system runs OK with the new drive connected externally install it in the system and see if it boots. If it does you are good to go. If it doesn't then it is more then likely the cable that hs failed.
I would suggest you also SAVE a copy of that download of Mt Lion and create a USB install drive from it using Lion Disk Maker, once you get your system up and running. -
I just upgraded to mountain lion osx and now my applications are crossed out and out of date. they will not run. how do i fix this?
Here is a recent post I assembled for a similar question:
Unfortunately you got caught up in the minor miracle of Rosetta. Originally licensed by Apple when it migrated from the PowerPC CPU platform that it had used from the mid-1990's until the Intel CPU platform in 2006, Rosetta allowed Mac users to continue to use their library of PPC software transparently in emulation.
However, Apple's license to continue to use this technology expired with new releases of OS X commencing with Lion (and now Mountain Lion). While educational efforts have been made over the last 6 years, the fact is that Rosetta was SO successful that many users were caught unaware UNTIL they upgraded to Lion or Mountain Lion.
Workarounds:
1. If your Mac will support it, restore OS X Snow Leopard;
2. If your Mac will support it, partition your hard drive or add an external hard drive and install Snow Leopard into it and use the "dual-boot" method to choose between your PowerPC software or Lion/Mt. Lion;
3. Upgrade your software to Intel compatible versions if they are available, or find alternative software that will open, modify and save your data files;
3. Install Snow Leopard (with Rosetta) into Parallels:

How can i update my old 2006 iMac Intel core 2 duo running 10.6.8 to OSX Lion so that I can sync using iCloud with my newer devices? Mountain Lion is not an option for my older model and Lion is no longer available at App store.
Call Apple's online store's telesales agents: 1-800-MY-APPLE (1-800-692-7753) or Customer Service and Sales Support at 1-800-676-2775. For Lion you'll get a redemptions code via e-mail and need to DL from the Mac Apple Store (requires SL 10.6.6+).

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. -
I've downloaded AirPort Util 5.6, in order to manage my Gen 1 Airport Express - because Airport Util 6.0 won't recognise it.
But when I go to mount, it says Airport 5.6 it can't be installed as my version of OSX (latest Mountain Lion) is not supported/does not support on 5.6.
Super unhelpful error messages bringing back memories of using Windows...
Anyone sussed this, or have Apple just fazed out the original Airport Express hardware on the sly?Generation 1 AirPort Express is Model No A1264. Check the side of your Express to look for the model number there. AirPort Utility in Mountain Lion will configure this model.
More likely, you have an older "b/g" version of the Express. Apple started the "Generation" thing with "n" capable devices. The Model number of your device is likely either A1084 or A1088. AirPort Utility in Mountain Lion no longer supports these older "b/g" devices.
If you have a Mac there running an earlier version of the operating system, you can use that to configure the Express.
Or, there is is workaround to install AirPort Utility 5,6 for Lion on Mountain Lion. See this article for details:

After upgrading to Mountain Lion OSX 10.8.2, my HP Photosmart printer is not working
My HP Photosmart 380 series printer is no longer working since upgrading to the Mountain Lion OSX 10.8.2. Need to know where to find installation software and updates so that it shows as an available and working photo printer. Also need how to information to make this happen. Any and all help will be appreciated.
Run Software Update to install the latest HP printing software. If the printer still doesn't work, follow the instructions linked below:

I bought a MacBook Pro (13" retina display) today. Tried to update software. Error mesage said to ujpdate OS. When I tried to, error message said, "OS X Mountain Lion is not compatible with this computer." Anyone else had this problem? Any suggestions?
All owners of the model seem to have the same problem. Presently there is no 10.8.2 updater for your model. The previous updater has been pulled. Wait a while and one will show up when Apple gets it fixed.

Mountain Lion OSx. Big problems following upgrade
i have just installed mountain lion OSx as an upgrade on MacBook Early 2009. Now various apps don't work e.g. iPhoto, iWork. Also Safari keeps crashing. Should I try to unistall and go back to my old reliable OS or try to sort it out as a complete novice ? All help greatly appreciated.
Back up all data.
Boot in safe mode.* This will cause certain caches maintained by the system to be rebuilt. The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
Safe mode is much slower to boot than normal.
When the login screen appears, reboot as usual (not in safe mode) and test. There's no need to log in while in safe mode.
*Note: If FileVault is enabled under OS X 10.7 or later, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. In that case, proceed as below.
You must be logged in as an administrator to carry out these instructions.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Triple-click the line below to select it, then drag or copy into the Terminal window — do not type — and press return:
sudo update_dyld_shared_cache -force
You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up.
Reboot and test. -
TS1413 computer stuck after mountain lion osx install
computer is stuck after trying to download mountain lion osx?
Hi , and a warm welcome to the forums!
Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
If perchance you can't find your install Disc, or are running 10.7+, at least try it from the Safe Boot part onward.
If 10.7.0 or later...
Bootup holding CMD+r, or the Option/alt key to boot from the Restore partitiion & use Disk Utility from there. -
I have mountain lion OSX and parallels with Windows. Every time I click on a hyperlink in other applications it opens - some 7 Zip file explorer inside Parallels but doesn't go to Safari. Does anyone know solution?
I suggest that you run software update, after which you should have Safari 6.0.5 - then check Safari - Preferences - Privacy & see that 'Block cookies' is not set to Always.
Failing that - switch Safari extensions Off via Safari - Preferences - Extensions & test again -
