Grey screen with question mark on boot up.

My son's 2011-12 Macbook Pro displays a grey screen with a question mark and will not boot. I pulled that first drive, put that first drive in a USB cage and connected the USB cage through a USB port and could boot a different machine with the first drive. I put a brand new second drive with a formatted and journaled OSX drive in place of the original first drive in my son's macbook pro machine tand got the same grey screen and question mark. Do I need a new electronics board? If so that is a $500 repair and not worth it on a 3 year old machine. Thoughts?

It could be anything at this point - most likely, it seems, is that you've a faulty SATA cable. If you go to www.ifixit.com you can find the Apple part number for the cable (or buy the cable at ifixit, even) and search eBay for the part number (much less expensive on eBay and I've yet to hear of one from eBay having failed).
I'm betting that's the problem.

Mac OS X Leopard not working (grey screen with question mark appearing)

Hello. I have a Desktop Mac Running on Leopard (not Snow Leopard) and it gives me the grey screen with a question mark. It has been doing this for a month now, and i had to restart it holding the C key every time, and now it has stopped working. I am using a Logitech mouse and keyboard, and had a disk inserted so i cant insert the installation disk. What should i do?

You will have to reinstall OS X. Connect the original keyboard and mouse. Restart the computer and hold down the mouse button immediately after the chime. This should force the optical drive to eject the disc. Otherwise see the following:
Five ways to eject a stuck CD or DVD from the optical drive
Ejecting the stuck disc can usually be done in one of the following ways:
1. Restart the computer and after the chime press and hold down the left mouse button until the disc ejects.
2. Press the Eject button on your keyboard.
3. Click on the Eject button in the menubar.
4. Press COMMAND-E.
5. If none of the above work try this:
Open the Terminal application in your Utilities folder. At the prompt enter or paste the following:
/usr/bin/drutil eject.
If this fails then try this:
Boot the computer into single-user mode. At the prompt enter the same command as used above. To restart the computer enter "reboot" at the prompt without quotes.
Once the disc has been removed you can try to do the following:
How to Perform an Archive and Install
An Archive and Install will NOT erase your hard drive, but you must have sufficient free space for a second OS X installation which could be from 3-9 GBs depending upon the version of OS X and selected installation options. The free space requirement is over and above normal free space requirements which should be at least 6-10 GBs. Read all the linked references carefully before proceeding.
1. Be sure to use Disk Utility first to repair the disk before performing the Archive and Install.
Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger.) 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, then quit DU and return to the installer.
2. Do not proceed with an Archive and Install if DU reports errors it cannot fix. In that case use Disk Warrior and/or TechTool Pro to repair the hard drive. If neither can repair the drive, then you will have to erase the drive and reinstall from scratch.
3. Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When you reach the screen to select a destination drive click once on the destination drive then click on the Option button. Select the Archive and Install option. You have an option to preserve users and network preferences. Only select this option if you are sure you have no corrupted files in your user accounts. Otherwise leave this option unchecked. Click on the OK button and continue with the OS X Installation.
4. Upon completion of the Archive and Install you will have a Previous System Folder in the root directory. You should retain the PSF until you are sure you do not need to manually transfer any items from the PSF to your newly installed system.
5. After moving any items you want to keep from the PSF you should delete it. You can back it up if you prefer, but you must delete it from the hard drive.
6. You can now download a Combo Updater directly from Apple's download site to update your new system to the desired version as well as install any security or other updates. You can also do this using Software Update.

TS3423 my start drive not responding. getting grey screen with question mark in a folder. when i use disk utility drive wont mount

When I turn on my Mac I get a grey screen with a folder with a question mark . Have tried the disk utility to no avail as the disk has apparently dismounted and will not mount even though the mount option is available. I have recently upgraded from snow leopard go os x maverick

This could be a software/state problem or a hardware problem. In your case it sounds like the latter but you should try the steps below in case it might help.

Grey screen with question mark on folder?

Just turned on my MacBook and it opened up with a grey screen with a folder in the middle with a question mark, what does this mean? I am also hearing a clicking sound from inside the computer.

frederic, with due respect: this solution is good if the disk is good, if the disk is dying, therefore ? is not due to a corrupt system, but a dying disk, then this solution may impede later recovery of data, which is still possible, if need be and if the disk is not entirely dead. Usually they do not not die over night.

How do I fix grey screen with ? Mark Blinking

Please help me to fix grey screen with ? Mark blinking thanks

The support article linked below is somewhat outdated. Where it refers to starting up from an installation disc, you should instead start up in Recovery mode.
If you don't have a current backup of all the data on the startup volume, and you want to preserve that data, then you must try to back up before you do anything else. Ask for instructions if you need them.

Help: Got the dreaded grey folder with question mark

Hey folks,
I was working in Chrome on my 13" mid-2010 MacBook Pro running OSX10.6.8, plugged in the mains charger and instantly had an unusual (not the beachball- the daisy from start-up and shut-down) freeze-up of the computer. I couldn't force quit and so shut the computer down using the power button (something I have done perhaps four times in its life-time).
On start up I got the dreaded flashing grey folder with question mark and know that this is serious. Last week I had a half hour with the U, I and O keys not working and that despite being very, very nice to my machines and repairing permissions and not unduly installing rubbish.
So I have inserted the start up disk for the MacBook Pro to see if I could use Disk Utility. And got it started (unusually load "whirring" too but I attribute this to heat) and Disk Utility cannot find the disk to repair permissions.
Now- from what I understand it means the hard drive is gone, right? Anything that can be done to save it (I cannot afford a new one)?
If not- how do I get the bits of data on there which I had yet to back up? CAN I?
Please and thank you.

So I fitted a new 500GB solid state drive from Samsung (easy enough- only a few screws on the lid, four screws holding it down and four more for the "pins" to hold it in place) but now, when I start up (bearing in mind that the install disk is stuck inside)- I get the Apple logo, then the daisy clock and then, woe is me, the "no entry" sign and eventually the install disk kicks in only to reveal that there is no hard drive to install to. Disk Utility and Start Up Disk both do not recognise it.
Any ideas what I can do, given that it is not rocket science to install one of these, given there is just one cable to connect and the rest is just to keep it in place?

Folder with question mark + wont boot from disk

Hi
I am trying to reinstall a powermac g5 from the disk, using a old hard drive that works.. (formatted in NTFS) (hoping that when selected to boot from disk, mac will then erase and reformat it)this image is presented when i hold down the option key and the disk ejects this other image is presented when i hold down C (folder with question mark blinking) and the disk ejects... also presented if i boot normally.... Could some help be offered please??????
Powermac G5
Thank you in advance

Yes, you must Format it HFS+ first...
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.*
How to format your disks...

Folder with Question Mark on Boot

I can't get my mac to boot. Instead I get the gray screen and a folder with question mark icon. I'm guessing the HD is dead? Any chance for recovery? If not how much does a new one cost? The one year warranty just expired!
Please help!
Thanks,
Brian

So, what is it? The thing froze today and wont reboot - just a gray screen with NOTHING. Then after about 10 min. the flashing question mark folder appears.
So, I popped in the install DVD that came with the computer, get the little gray Apple logo and it boots from the DVD.
Launch Disc Utility. The HD appears on the left. Click on it - all of the "Verify" and "Repair" buttons remain grayed out. So what the hxll do I do?
I cant boot into single-user mode or any other mode for that matter.
This is a Macbook pro, dual-core Intel, less than a year old.

Re iphoto: when I double click on a thumbnail i get e grey screen with exclamation mark..can't access my photos to edit, order prints etc

Was wondering if anyone can help...I am not very computer friendly but want to be able to edit my photos, use them as jpegs, order prints etc. When I double click on a thumbnail ( am presuming the thumbnails are the small photos ) I get a grey screen with an exclamation mark on it. I cannot drag the thumbnail onto the desk top it just pings back. This doesn't happen with all the thumbnails and has been a problem since we upgraded to snowleopard. I recently reinstalled photos from the memory card from my camera and they are alright. I am presuming that the old photos are stuck in there somewhere if only I knew the right buttons to press to get them out. Thanks, Jane Thomas

Easiest: Restore from your back up.
Otherwise:
Try these in order - from best option on down...
1. Do you have an up-to-date back up? If so, try copy the library6.iphoto file from the back up to the iPhoto Library allowing it to overwrite the damaged file.
2. Download <a href="http://www.fatcatsoftware.com/iplm/"><b><u>iPhoto Library Manager</b></u></a> and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.
3. If neither of these work then you'll need to create and populate a new library.
To create and populate a new *iPhoto 6* library:
Note this will give you a working library with the same Rolls and pictures as before, however, you will lose your albums, keywords, modified versions, books, calendars etc.
Move the iPhoto Library to the desktop
Launch iPhoto. It will ask if you wish to create a new Library. Say Yes.
Go into the iPhoto Library on your desktop and find the Originals folder. From the Originals folder drag the individual Roll Folders to the iPhoto Window and it will recreate them in the new library.
When you're sure all is well you can delete the iPhoto Library on your desktop.
In the future, in addition to your usual back up routine, you might like to make a copy of the library6.iPhoto file whenever you have made changes to the library as protection against database corruption.

Grey screen with question in folder

The color wheel would not go away after several minutes. I turned off the MacBook and then turned it back on . I got a grey screen with a flashing folder with a ? In the folder.
What do I do?

It looks like your hard drive has disappeared. Could be any number of reasons, including a dead hard drive.
If you can, I suggest you make an appointment at an Apple Store genius bar, and ask them to diagnose the problem. That service is free.

You will have to pay for repairs, unless the Macbook is under warranty.

White Screen, Grey Folder with Question Mark and no USB

Hello
I have a iMac, that is in a classroom of similar machines, they are running os v 10.4.6 (ish).
The mac in question had been reported with a fault so i went along to check it and this was a new fault for me.
When the mac boots, it bongs the hdd starts up and then a black white screen appears after a few minutes this changes to a white screen with a flashing grey folder with a question mark.
now reading on the forums, internet etc. i have found that maybe i should boot to disk. tried this but not disk activity.
next i read to boot into verbose mode at which point i find that the USB ports dont seem to be running so i can use a keyboard.
Anyone any ideas how i can troubleshoot this problem or why the problem occurred in the first place?
Thanks for any help offered.

This error indicates either that the internal HD has physical problems, or there is corruption on the drive (a failing directory or corrupt system files). You should boot from the Mac's original installation disk, run Disk Utility from the Utilities menu and do Repair Disk on the internal drive. If this fails to recover the drive, you may have to reinstall the system.

Blinking grey folder icon with question mark on boot

Hi. Just got my system from the Apple Service center where they have reinstalled a new hard disk for me.
When I come home, and start the machine, it shows me a blinking grey folder icon with a question mark in it.
Only thing I can do in this screen is switch off the power. But when I reboot, it shows me the same icon again.
With google, I discovered that if while rebooting I press the OPTION key, then it boots me into the firmware password mode. How can I automate this? I do not want to have to always boot the laptop with Option key pressed.
Thanks for any pointers.

That question mark means that your machine can't find a drive with a system installed to boot from. Sounds as if the techs didn't install a system when they replaced the drive... do you still have the installation disc(s) that your MBP might have come with?

White screen with grey folder with question mark?

My Mac froze when I opened iTunes and I turned it off and when I turned it on it was grey an I restarted or and now it's white with grey question mark?? What do I do? I don't want to loose my stuff.

Question (?) Mark, Blinking Folder, or Gray Screen at Startup
These are related but not identical issues. Their causes are outlined in Intel-based Mac- Startup sequence and error codes, symbols. Solutions may be found in:
A flashing question mark appears when you start your Mac
Mac OS X- Gray screen appears during startup
In most cases the problems may be caused by:
Problem with the computer's PRAM - See Resetting your Mac's PRAM and NVRAM.
Boot drive's directory has been corrupted - Repair with Disk Utility.
Critical system files are damaged or deleted - Reinstall OS X.
The disk drive is physically non-functional - Replace the hard drive.
Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. 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 installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
The main difference if you are using Lion or Mountain Lion is that you must first boot from the Recovery HD:
Boot From 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.
Reinstall Snow Leopard Without Erasing The drive

2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install Mac OS X 10.6.8 Update Combo v1.1.
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.

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.

Grey screen/ flashing question mark folder help!

my macbook starts up into the grey screen (no logo or indicator) and will eventually go into the flashing folder with the question mark. After hours of scouring forums I have tried the following things:
restart holding c with install disc in -> macbook spins disk, thinks, ejects disk
restart holding option -> grey screen, this time with movable cursor, does not advance from there. i left it for about ten minutes- should i leave it longer?
reset PMU as per Apple article -> no effect
reset PRAM as per Apple article -> no effect
i'm beginning to become resigned to the fact that it might be an HDD issue. i feel as though i should still be able to boot from disc. i could be wrong. just wondering if anyone has ANY other suggestions before going to Apple for repairs.

If the computer is under warranty the cost is carried by Apple. If it isn't, here's what I'd do...then again, I'm a tech and have access to lots of equipment. First I'd remove the drive (easy to do. turn off the computer, remove the battery, remove the little gate, remove the drive. The instructions are in the little booklet that came with the computer) and put it into an enclosure, connect to another computer and run drive diagnostics. If the drive can be repaired I'd format it, clone from my backup, and return to the computer. If the drive is dead I'd buy a new drive, clone from my backup, and be back up and running. There's a third, remote possibility - that the problem is the logic board and not the drive. But it is remote.
What I'm getting at here is that yes, you can do it yourself but...you probably don't have an enclosure for a 2.5" drive so you'll probably just have to assume the drive is toast and buy a new one - check out NewEgg or Macsales.com. Without the external drive enclosure you give up the chance of restoring the drive and recovering data. Then again, if you can't anyway you'll have wasted $$$ on an enclosure you didn't need.
Instead of worrying about what you've heard, call the local store and get a quote on replacing the drive and installing a drive that you bring yourself. That'll give you a ballpark figure to work with and you can move forward from there.

White Screen with Question Mark Flashing

Hi
All the sudden I have the white screen with the flashing question mark. I have a macbook pro 2010. I unscrewed the bottom of my Mac and wiggled a couple of wires around and it actually booted up and ran for a while. Then it started to freeze on me. I put in the Mac disk, and I went to the disk Utitlity and it says disk 2 Mac OS X Base System. So it looks like it is reading the Hard Drive, but I don't know because I do not know that much about computers. The thing is it will not let me erase or repair that drive. Does anybody have any idea on what this is? I used my computer around 1:30 in the afternoon and then came home to do homework around 5 and in a matter of 4 hours my computer does not work. I am guessing that it is probably something serious and I will not be buying mac again.
Any Help??
Thanks,
Matt
