MBP Won't load - stuck at grey apple logo

Ok here's my dilema ...
I've read posts about this same problem but I can't get this mbp to do any of the suggested fixes!!
Here's where I screwed up....
I was playing around with iWeb 09' trying to make a better website for my company... when all of a sudden it wouldn't load from the tool bar it would bounce up and down once or twice and nothing would happen.
I then by mistake put the file on my desktop then wanted to get rid of it so I dropped it into my trash. oops!
Well then everytime I clicked on iweb it would say file is damaged or incomplete.
So when I got home from work I decided to try to reinstall the application with the app disk that came with my computer.
Well instead of being patient and figuring out how to install just the iweb app. I reinstalled the whole bundle !! oops again... I know I don't deserve to be a mac user !! but I've fell in love!!
OK now the install finished and it asked me to restart now so I did ... and this is where I'm stuck...
It restarts and goes to the apple grey screen with a small bar that starts to load and then disappears and gets stuck at the spinning gear.
I've manually ejected the disc by holding down the trackpad. And I put in the os x disc and tried to get into setup by holding down C after I hear the chime and until I see the spinning gear and that doesn't pull up anything!!
What should I do?? PLEASE HELP!!

Hello and welcome to the discussions, I would try three things first. I reset SMC (unplug the MBP and remove the battery. Then hold the power button down for at least 20-30 seconds) Replace battery, plug in and try starting in Safe-Mode (press and hold the left "Shift" key after hearing the startup tone. Release when you see the Apple logo. Safe-Mode takes a long time to load...be patient.
Next I would try to repair the disk. Start in Single-user mode (Press and hold the "Apple/Command" and the "S" keys after hearing the startup tone. Release when you see the Apple logo or the screen goes to a black and white text. If this works wait for a command prompt it will be a "#" then type in "/sbin/fsck -fy" No quotation marks and a space between fsck and -fy.
This will repair the disk. If ANY repairs are made repeat the above command until none are made.
Then type "reboot" again w/o quotations.
Third I would boot in Verbose mode (press and hold the left "V" key after hearing the startup tone. Release when you see the Apple logo or it starts displaying text. The MBP will freeze at some point but you will be able to see what is failing. Write it down and get back to us.
Cheers,
Glynn

My powerbook won't load past the grey apple logo screen

I had been away on business for a few weeks and yesterday I decided to run the latest updates for my powerbook. In the middle of it the computer froze for what I think is the first time since I bought it 2 years ago. I ended up having to shut the computer down with the power button. When I turned it on it wouldn't and still won't advance past the grey apple logo screen with the progress indicator. It just sits there for hours on end if I let it.
So far I've tried the following, all to no avail.
Booting in safe mode I get the same result.
Zapping the Ram
Resetting the PMU
Reinstalling OS X, during which the computer either randomly shuts down or goes to sleep and then shuts down and requires me to reset the PMU in order to start again.
Running the hardware diagnosis. I did this once and it froze during the logic board test, 1 minute 6 seconds in to it.
Anyone have any ideas that don't involve spending 900 dollars on a logic board? Thanks a lot for any help.

joeuu, thanks for the reply. i checked the airport and the ram and both seem to be seated properly.
i ran the quick hardware diagnosis and it came back showing everything was fine.
when i ran the extended one i got more progress than i did the first time. it got to the RAM diagnosis (about 6:45 seconds in) and then froze - i let it sit like this for an hour and a half to make sure it was actually frozen.
i also tried to run the disc utility from the installation disc and it just sits there with the progress wheel spinning, but nothing else is going on.

MBP won't boot. Gray screen, apple logo.

As above, my 2.4 Macbook Pro, won't boot past the gray Apple logo and that spinning circle.
Holding C doesn't allow it to boot from CD either, for Leopard/Tiger OR Disk Warrior!
Holding alt allows the start up menu, but then spits the CD out and only shows the Macintosh HD which obviously wont boot!
HELP!
MBP 2.4 / 10.5.2

Have you tried zapping the PRAM?

PowerPC Mac Mini gets stuck at grey apple logo screen, wont start

I have a bit of a problem and would appreciate some help, im not especially good at this stuff.
My Powerpc Mac Mini froze up recently, having left it on for a few days without shutting down/resetting. I impatiently turned it off with the power button at the back. When I turned it on again, it only got as far as the grey apple logo screen, it now refuses to go past this screen despite numerous power resets, and unplugging at the power.
I have reset the PMU and the PRAM as suggested by the troubleshooting, to no avail - the PRAM did work as it changed the resolution of the apple logo, but still got stuck at the grey startup screen. Its out of warranty so I have to pay for technical support. Can anyone help?

If you have the original install disk that came with your mini, the first thing to do is to insert that, and then boot the system holding the C key down. This should force it to boot from the install disk rather than the internal drive. The reason you want to do this is two-fold: firstly that if it boots OK that way, it shows the basic hardware is OK, and secondly, it's possible that the hard drive has developed errors (likely directory damage) and the tool to check for that and attempt to resolve it is on the install disk.
Once you've got the system booted to the install disk, exit the installer and run the Disk Utility application. That should display the internal drive (and the install disk) on the left. Select the internal drive and then click 'Repair Disk'. If no errors are found, the drive is fine and the problem lies elsewhere. If errors are reported and the disk is fixed, then you should be able to reboot normally afterwards. If errors are found and Disk Utility reports 'error on exit' not having fixed them, then run it again just to be sure, but otherwise it means the drive is damaged sufficiently that Disk Utility can't fix it. A third-party application such as Alsoft's DiskWarrior will then be needed if you want to try and fix the drive and recover data, or you can simply elect to do an erase and install, meaning the drive will be reformatted and a new copy of MacOS installed. Do not do this if you have data you need to get off the drive!!

Sometimes iMac "stuck" at Grey Apple Logo during starting up...

Hello all.
I have this very intermittent problem with my iMac, it happens like here and there so I "don't really consider it now as a serious problem"...
My iMac has a FW800 external hard drive connected as a Time Machine drive, and two 7-port USB hubs connected (but not all ports are used up - namely iPhone, 3 iPods, printer, wacom tablet etc)
I have to stress I have not have any problem with this connection in my previous iMac model (all plastic white) and when I first got this iMac, until most recently.
*When I start up the iMac as usual, it will "get stuck" at the Grey Apple Logo screen*, I know that the mac has somehow "freeze" is because the animated scroll-wheel below the logo is not there (normally it will be there, "circulating")
The only option I have is to press the back Power button, *shut down the iMac and start up again, normally the 2nd start up will be fine.*
Anyone if you have any ideas or know what's going on, please let me know
Thanks and cheers

Sounds like some maintenance might be necessary (if it's not hardware related). Check out the xlab recommendations: http://www.thexlab.com/faqs/kernelpanics.html
My G5 iMac occasionally freaks out like that too, but I've done a complete erase and reinstall of the OS, so I think it's a hardware issue...possibly some weird RAM. You might do a test removing each stick and testing.

External start-up disk not loading stuck at grey apple screen?

Hello,
I used to have a 2010 13" MacBook Pro, I sold it back in December so I took out the hard drive and placed it in an external case. I've been using the case since then and I usually started up from my external HD on other MBPs that relatives lent me now and then. Yesterday I got a new 2011 15" MBP and I decided it would be a better idea to just copy my documents (incl. fonts and VSTs) and music and do a whole reinstallation of all my applications. Unfortunately there's certain stuff I can't just copy from my old HD so I decided I'd start up from it and write some stuff down for later. After plugging the hard drive and starting up the computer with the external as a start up disk, the grey screen with the apple logo shows up, although no spinning wheel shows up. The computer then stays like that forever until I decide to shut it down by holding the power button.
I opened up Disk Utility and although I can't do anything about permissions (both buttons are grayed out), I verified the disk and everything turned out fine. Can you please help me why I can't boot up from it?
Thank you very much for your time.

Two thoughts.
1. The OS on the old HD is specific to the old MBP and won't boot the new one.
2. Macs will not boot from an OS version that is older than the one current at the date of manufacture.

OS X won't start; stuck on the Apple logo

I went out of town on Friday and shut down my iMac G5 (Intel, purchased brand new January 2007). When I got home today and tried to boot it up, it stuck on the grey screen with the Apple logo and spinning gear. It will stay there until I either unplug my iMac or hold down the power button until it shuts down. This happens every time I attempt to boot OS X. I try to start in Safe Mode (holding down shift), but get the same result, same when I unplug all peripherals. I can, however, boot Windows XP via Boot Camp, which is what I am using to access the internet right now. Everything seems to be working perfectly in Windows XP, but it won't boot at all in OS X. I don't have access to my Install disc right now (It's at my dad's house; we got the family version of Leopard.), but I could get it if I absolutely have to.
Any suggestions? Thanks.

Your problem may be different, so it might serve you better to start your own thread. That said, both problems occurred when switching locations, so I wonder if the network/wifi might be involved. However, Niels, if you are unable to start at all, with any of those methods, there may be something more serious involved (we have had no feedback from the OP in the last few hours).
Showing the last screen suggests a total (and unusual) freeze with the computer not having shutdown or gone to sleep. Did you close the lid and leave it? If you cannot start with the disk or with the Option key it is not simply the OS gone awry, IMO.
Last resorts?
One thing not tried is to hold down the Command, Option , P , and R keys on the keyboard to reset PRAM.
Also, as a really last resort, hold down the Command, Option, O, and F keys. A grey screen will appear with a command line. Type +reset all+ and if that does not work, it is off to the shop.

MacMini won't boot, stuck on the Apple logo

Hi,
I suddenly had an issue with my Mac Mini. It started to take long seconds, even minutes, to load a software (with the round cursor turning). So I decided to restart it but, how surprise, it got stuck on a blue screen. A few more try to shut down and start again, including with the original install DVD, but it's now stuck on the screen with the Apple logo on white background...
Here is what I have done so far:
- removed all the stuff connected to it, there is only the external screen left (mouse and keyboard are wireless).
- tried to start it in safe mode, but nothing happens, it's still stuck on the same Apple screen
- tried to start with the original install DVD, not better (DVD is actually now stuck in the Mini, I can't get it out...)
- tried to start it with Command-S, and a Read Error was displayed. See attached picture of the whole text displayed.
Any idea what this means?
Thanks a lot for your help!

This happened to me last night.
I was updating my iPod and I got a message saying that it needed to do an update. I installed the update and went on ahead putting new songs on my iPod. When it was finished i ejected as I usually do and closed down.
When I went to check me e-mails this morning the Macbook would not boot. It sticks on the grey screen with the Apple and the spinny disc underneath, then it restarts and sticks on the same screen. The last software to be onstalled was Norton 11 on Monday but I have used the Macbook since. I cannot think why it will not boot.
I am loathed to do a reinstall as I have some things on the Macbook that I had not yet backed up.
Any advice?

MacBook won't boot - stuck showing the Apple logo and the spinning circle.

Hi.
My MacBook suddenly froze when I was using it today. Displaying the spinning beach ball.
It never came out of it, fan running at max speed, so I tried to force restart it (Control-Command-Power), but that didn't work, so I forced the MacBook off (holding the power button pressed.)
When trying to start the MacBook again it couldn't boot. It kept displaying the grey screen, with the Apple logo and the spinning circle below the Apple logo.
I left the MacBook like this for 10-15 minutes, but nothing happened.
Went on to try the following.:
*- Removed the AC-adapter and battery for 5 minutes.*
*- Command-Option-P-R (Resetting PRAM and NVRAM).*
*- Resetting System Management Controller (SMC).*
*- Command-S (singleuser boot)*
And checking the HDD with sbin/fsck -fy
= "The volume ** appears to be OK."
*- Command-V*
Stops on the following line, and fan ramps up to full speed.:
DNSServiceRegister("ssh.tcp."): -65537)
Force reboot didn't work. Had to force it off.
But, nothing helped.
It simply won't boot.
I also tried to boot Ubuntu 7.10, but it hangs after a short while displaying "Kernel panic".
Force reboot didn't work. Had to force it off.
Also tried the option to boot from the first HDD (in the boot menu on the Ubuntu 7.10 disc), but that didn't work either. Only got a black screen, with a blinking cursor top left, and fan ramping up to max.
Again, force reboot didn't work. Had to force it off.
The only thing that has worked so far is exiting the Ubuntu 7.10 CD boot menu, and pressing enter on the prompt that appears.
But, after rebooting, the MacBook still refuses to boot into Mac OS X.
I left the MacBook alone, hoping it would work its way out of the spinning circle, but after 2 h 38 min nothing had happened.
Does anyone know how to fix this?

Macbook pro stuck on grey apple logo screen - HELP! I've tried everything

I've looked through the forum for help and I think I've tried everything short of erasing and reinstalling mac os x -
- I've done an fsck (got "invalid volume count", "invalid node structure", "volume check failed" errors)
- booted from install disk and tried to verify disk (same errors as above)
- tried to "archive and install" mac os but got error saying "the destination disk must be erased for installation"
I tried T-starting my laptop connected to another mac (a powerbook g4) to try to backup my files before erasing and reinstalling mac os - but the mbp hard drive won't mount on the powerbook.
My latest idea is to try installing mac os x onto an external drive - and then booting my macbook pro from the external drive... and see if I get anywhere. my only concern is, I have to make SURE the option saying "Install Mac OS X - Installs Mac OS X for the first time" does NOT delete the contents of the external drive (it is a client's and cannot be erased!). I know there is also the option that says "Erase and Install" -- but I just want to make sure the first option will NOT delete the contents of an external drive.
Anyone know for sure? Or have any other suggestions? I have some work on my macbook pro that I cannot lose. Unfortunately I have not been backing things up... big mistake that I will not repeat.
Thanks in advance.

DiskWarrior is the answer, as sig has suggested. It can sort out directory damage that is well beyond Disk Utility's repair capabilities. If you already had a bootable external hard drive of your own, I'd urge you to buy and download DiskWarrior and install it on the bootable external drive, then run it from there to rebuild the directory on your internal drive. I have to say that using a client's hard drive to solve your own problem would be appalling and unconscionable, and I hope you'll forget that idea.
If you can't see your way to buying an external hard drive along with DiskWarrior, you'll have to buy DW on a bootable disc, or order one online and wait for it to arrive.
If you can buy an external hard drive of your own in addition to DiskWarrior — and I can't think of any better use for a credit card, if cash is short — then you'll be able to boot your MBP to a Leopard installer disc, install Leopard on the new external drive, and then buy DiskWarrior as a download (rather than on a disc) and use it as I described above. After sorting out the internal drive with DW, clone the internal to the external drive with SuperDuper or Carbon Copy Cloner, and there's your backup from now on.
I should add that although Western Digital external hard drives seem to be available cheaply everywhere, I strongly recommend against buying one. Seagate drives are also widely available, and would be a better choice.

Brand new MBP stuck on grey Apple start up screen

My new MBP 13" arrived today. I removed the SSD from my current Macbook and installed it in my MBP. I pressed the power button, and it got stuck on the grey start up screen with the grey Apple for 5 minutes. I shut it down and put the SSD back in the Macbook - worked perfectly. So I tried installing it again in the MBP, and had the same problem. It just stays stuck on the grey screen with the Apple.

Last night the electricity went out and my power surge protector was not working so my iMac just force shut downed.
So, when the electricity came back i turned on my Mac but it is *Stuck in the Startup/Boot Screen with a Grey Apple Logo,a Empty Progress Bar with stays for 1 or 2 minutes and a small Spinning Wheel which would Spin Forver! I Have tried the SMC and Pram reset but no use, i have also tried to insert my OS X Lion 10.7 Installation disk and it would not load if i hold the C Key in the Startup, I Have Managed to go to Disk Utility Through "Recovery HD" but the Volume "Macintosh HD" is Greyed out and Unmounted and i cannot repair it. There are some files that i'd like to Recover if there is a way to fix it without deleting files.
**PLEASE HELP ME FIX THIS!**
Details about the iMac:
iMac 21.5 Inch i think from Mid 2010,
OS X Lion installed maybe 10.7.2 or 10.7.3 (im not sure)

My computer won't load pass the grey start up screen

    MacBook pro won't load pass the grey start up screen?

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a boot failure is to secure your data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since your last backup, you can skip this step.
There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.
     a. Boot into the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 3
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 4
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
Step 5
Boot in safe mode. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you boot in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, your boot volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 5.
If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then reboot as usual (i.e., not in safe mode.)
If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 6
Launch Disk Utility in Recovery mode (see Step 1.) Select your startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then reboot as usual.
Step 7
Reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 8
Repeat Step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a Time Machine or other backup.
Step 9
This step applies only to older Macs (not current models) that have a logic-board ("PRAM") battery. Both desktop and portable Macs used to have such a battery. The logic-board battery is separate from the main battery of a portable. A dead logic-board battery can cause a boot failure. Typically the boot failure will be preceded by loss of the startup disk and system clock settings. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 10
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested. If you can't get to an Apple Store, go to another authorized service provider.

My 2009 iMac gets stuck on the grey Apple logo when booting up. It boots correctly when in safe mode. I have tried erasing the HD and re-installing from a USB installer. It says the install is complete, but after restarting it gets stuck on the Apple log

My late 2009 27" iMac gets stuck on the grey Apple logo when booting up. It boots correctly when in safe mode. I have tried erasing the HD and re-installing from a USB installer. It says the install is complete, but after restarting it gets stuck on the Apple logo again. This could possibly be an HD failure, but then why does Safe Mode still work and the USB install not work? Any ideas?

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
Don't be put off merely by the seeming complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. All it does is to collect information about the state of the computer. That information goes nowhere unless you choose to share it. However, you should be cautious about running any kind of program (not just a shell script) at the behest of a stranger. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them. Ask for other options.
Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it.

Copy the selected text to the Clipboard by pressing the key combination command-C.
7. Launch the built-in 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.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
8. If you see an error message in the Terminal window such as "syntax error," enter
exec bash
and press return. Then paste the script again.
9. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
10. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report the results. No harm will be done.
11. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with "Model Identifier." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
12. When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If that happens, please post the test results on Pastebin, then post a link here to the page you created.
Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

Mac Stuck at Startup Screen with Grey Apple Logo,Empty Progress Bar and a Spinning wheel

Last night the electricity went out and my power surge protector was not working so my iMac just force shut downed.
So, when the electricity came back i turned on my Mac but it is *Stuck in the Startup/Boot Screen with a Grey Apple Logo,a Empty Progress Bar with stays for 1 or 2 minutes and a small Spinning Wheel which would Spin Forver! I Have tried the SMC and Pram reset but no use, i have also tried to insert my OS X Lion 10.7 Installation disk and it would not load if i hold the C Key in the Startup, I Have Managed to go to Disk Utility Through "Recovery HD" but the Volume "Macintosh HD" is Greyed out and Unmounted and i cannot repair it. There are some files that i'd like to Recover if there is a way to fix it without deleting files.
**PLEASE HELP ME FIX THIS!**
Details about the iMac:
iMac 21.5 Inch i think from Mid 2010,
OS X Lion installed maybe 10.7.2 or 10.7.3 (im not sure)

kernel
Grey screen with Metallic Apple and spinning gear
Sounds to me like your hard drive failed on you as a result of the power going out.
http://www.apple.com/support/imac-harddrive/
If your iMac is a Mid 2010 you qualify for the hard drive replacement program from Apple.
Apple has determined that certain Seagate 1TB hard drives used in 21.5-inch and 27-inch iMac systems may fail. These systems were sold between October 2009 and July 2011.
I hope I helped you with your problem.
