TS2570 i see a folder and a question mark when i restart my macbook pro

i see a folder and a question mark when i restart my macbook pro

There are four general causes of this issue:
1. The computer's PRAM no longer contains a valid startup disk setting when there aren't any problems with the disk itself. This can be checked for by pressing the Option key and seeing if the drive appears.
2. The internal drive's directory structure has become damaged. This requires usage of an alternate bootable system to perform the repair.
3. Critical system files have been deleted. This requires usage of an alternate bootable system to reinstall them.
4. The internal drive has died or become unplugged. This is the most likely case if the computer took a sharp impact or there are unusual sounds coming from the hard drive's location.

My screen turns gray with a blinking folder and a question mark

My computer started going really slow so I tried to restart it. When it started to turn back on the screen just went gray for a minute or two then a darker gray folder with a question mark on it started blinking in the middle of the computer. little help?

Hi,
Before you buy a new hard drive, you may be able to get it fixed free of charge.
MacBooks equipped with Seagate hard drives model ST96812AS (and possibly other Seagate models)
with firmware 7.01 have experienced a higher than normal failure rates. The failure mode is that the heads detach from the positioning mechanism.
You can use System Profiler to see what type of hard drive is installed. If you have gotten the screen with the folder and blinking question mark, and you do have a Seagate ST96812AS installed, I recommend calling AppleCare or taking your Macbook to a retail service center. There is a good chance you may be able to get the drive replaced, even if your MacBook is no longer covered by a warranty.
The hard drive is considered to be a user serviceable part, so you might not have to send the entire computer in, but rather swap only the hard drive via mail.
Best wishes for a problem resolution,
Bill

Apple Macbook 13.3" Laptop-Black 2008 2.4GHz Intel Core 2 Duo will not boot up and instead I get a grey screen with a folder and a question mark over it.

My Apple Macbook 13.3" Laptop-Black 2008 2.4GHz Intel Core 2 Duo will not boot up and instead I get a grey screen with a folder and a question mark over it. I've tried Option key, and Control S keys and it still will not boop up. Can anyone help?

If you are running Snow Leopard:
Reinstall OS X without erasing the drive
1. 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.
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.

White screen with a folder and a question mark in the Folder

Hi,
My daughter's Desktop Mac Pro won't reboot. On reboot, it shows a white screen with a folder and a question mark within, It just stays there and nothing happens. Is this a problem with a dead hard drive, dead processor, faulty USB connection, problem with airport.? We need advise and help, please!
effie imperio

Hi, Anonymoustache, thanks for responding.
Yes, I think it is "a flashing question mark". If it is flashing, you think it is a hardware problem like a dead hard drive? I had a flashing question mark with my Power book G4 and Apple replaced a dead hard drive.
Thanks Hatter, I will convey your response to my daughter and see if it will help.

At startup see a folder with a question mark

At startup I see a folder with a question mark and the system will not boot. Loaded install disk but it can not find the hard drive?

Mac Said:
Additional steps
If your Mac still starts to a flashing question mark, follow the steps below. If any step resolves the issue, you don't need to continue to the next one.
Select your Mac OS X startup disk with Startup Manager by restarting and holding the Option key. After your Mac starts up, restart again to verify that the flashing question mark does not appear.
If the issue persists, insert your Mac OS X installation disc. Be sure to either use the disc that came with your Mac, or, if you installed a later Mac OS X version from disc, use the newer disc.
MacBook Air note: On a MacBook Air, there are two options for starting up from Mac OS X media: Either connect a MacBook Air SuperDrive to the MacBook Air via the USB port and restart the computer, holding down the C key during startup, or use Remote Install Mac OS X to startup from a system software DVD that's located on a partner computer. Once started up from Mac OS X media, skip to step 3.
Restart the computer, then hold the C key during startup.
From the Utilities menu, choose Disk Utility. Don't click Continue.
Select your Mac OS X disk (named "Macintosh HD" by default) in the left side of the Disk Utility window.
Click the First Aid tab.
Click Repair Disk to verify and repair any issues with your Mac OS X startup disk.
After repairing the disk, try to start up normally.
Important: If Disk Utility finds issues it cannot repair, you may need to back up as much of your data as possible (or use Time Machine to back up to a different disk), then erase the disk and reinstall Mac OS X. You should back up important files and data before erasing a drive. Erasing deletes everything on the hard disk (including things on your desktop). Also, you can install Mac OS X onto an external disk, start from the external disk, and use Migration Assistant to transfer items from your usual internal Mac OS X startup disk to the external disk, then erase the internal disk and reinstall Mac OS X.
If the issue persists, and Disk Utility didn't find any irreparable issues, quit Disk Utility, quit the Installer, select your disk when prompted, and restart.
If the issue continues, reset PRAM. Note: After resetting PRAM, if the computer starts up normally, reselect the startup disk in the Startup Disk preferences.
If none of these steps resolve the issue, start up from the Mac OS X Installation disc and reinstall Mac OS X.
if none of this works but you have to format the entire disk, which is not very fun forsomeone, and if you have important data on your disk that you need, how do you do?
yes I have a solution, but I do not recommend it unless you know what you're doing,
ask a technician who is this he will help you safely, otherwise send a pm to me.
first a little info about me, I'm IT technician then a couple of years and have never beena fan of the mac, and will probably not be there, because I think that off "giant optimized"systems have no security, personally, I want the mac to be release an update so it forcing / or remind the user to backup with time machine, so no I will not get me one of your machines, enough about that, I had a client who had this problem, (ps / something allhave to remember is that all customers are idiots and do not know what a computer realy are, that is why it remains "the rule 101"!
His desk was this apoblemet, and I am recommending not to open up his mac becausethis would guarantee his disappearance, he had also no backups at something so long story short, he was fu ***,,
However, he had all his business accounts on the computer and much much more, so hemade the choice to give me permission to open up the machine, I went through all theguides that were on the Internet and Disk Utility was not helpful at all, nor disk Wari disc to start up, even when I plug in the drive as an external drive on another mac wanted itabsolutely does not come up.
However, so when I connected the disk in a PC with Windows 7, install a program thatmade it possible to see the disk in my computer but could not go into it because then it said that there was something wrong, but then I thought for a bit spruce, windows can see all unknown hard disk format "RAW" guidelines for adding, then it's just to make a RAW backup (google it) and Woll! now i have a copy of all his data, would also like to point out that this may take time, so be patient.
[would also like to point out that if you choose to open the your mac, there is great risk that your warranty disappear, do so at your own risk!],
so if you really have to have a backup of data you need the following;
a PC whit windows
a Controller that convert SATA to USB
a program that makes creating a driver for HFS + disks
a back-up software for RAW drives
and last but certainly not least, patience.

Can you still boot to the Recovery partition using Command and R whilst booting? Or did you wipe the Recovery partition as well?
If your Recovery partition is still intact, you can simply boot to it and reinstall the OS via the Internet. If you wiped the Recovery partition, you can hold down Command, option and R keys whilst booting and boot into true Internet Recovery mode. You'll be able to reformat the hard drive, erasing all partitions (format it as "Mac OS Extended (Journaled)" with a dingle GUID partition) and then reinstall the OS that shipped with your machine.
Note that you should use a physical Ethernet connection when restoring over the Internet - it's three times slower if you use wifi.
Try your Recovery partition first and if that doesn't work, use Internet Recovery.

What does it mean when you computer crashes and when you turn it back on it shows you a blank blue screen with a little folder and a question mark in the middle?

What does it mean when you computer crashes and when you turn it back on it shows you a blank blue screen with a little folder and a question mark in the middle? It's a old imac from 1997.

I don't have original discs that it came with.
Then you still can use the second option with the keyboard combo I posted, called "resetting the PRAM."
Also when you way hold the c key down do you mean turn computer off and turn back on holding the c key?
Yes, or you can simply restart. As you don't have the CDs, this isn't on the plate any more.
The internal backup battery is not expensive and, in most iMacs is user-replacable. If yours has a tray-loading optical drive like this one:
it takes a major teardown to replace the internal battery. If this is the case, you'd be better off to leave the computer plugged in all the time; that eliminates the main reason for having a working battery.
If it has a slot-loading optical drive like this one:
things are much easier. The battery is visible through the RAM access door on the bottom of the computer case. The manual:
http://manuals.info.apple.com/en_US/iMacG3_2000UserManual.PDF
has sketches of how to access the RAM and therefore the backup battery. Unfortunately, the pdf on the manual goes up sideways on-screen and the RAM instructions are pretty deep into the manual. It's probably easier to scroll (for a while) to the section on adding RAM and print the applicable pages.
When you work on the battery, some sort of non-conductive pliers or large tweezer or forceps help unless you have tiny fingers. Make sure to note the polarity of the old battery and install the new one in the same orientation.
The battery itself is readily available. If price is no oblect, you can get it for a small rasom from Radio Shack Store ("Tandy" outside the US) as part number 23-026.
Online, they are dirt-cheap even after adding shipping. I buy backup batteries form this outfit:

Macbook Air - White/Grey Screen with a folder and a question mark

Out of the blue , my macbook air stopped starting up and strted to show me a white/grey screen with nothing but a folder and a question mark . After searching on the internet for solutions and trying to reset my PRAM setting , it still wouldn't boot up . I opened up disk utility and going through internet recovery , I ran the first aid verification on my MAC OS X Base System and it said that it found no problems . I can't restore or erase by the way and i really wouldn't erase my files as I have very important files on my mac . Moving on , I tried to reinstall OS X , but apperently it needs a disk to install OS x on and since none appear , I tried using an USB . After creating a partition and erasing everything on my USB , not happy about that , it wasn't big enough for the OS . So now I am basically stuck in the mac white screen Limbo .
Any sort of help would be fantastic and please do keep in mind that this is a macbook air and I do not have a place to put DVDs into . All I have read on different forum pages didn't help so i decided that it would be a good idea to create my very own thread . I am not very sure about the Mountain Lion version ,but I am not very sure that it matters .

Flashing file folder with a question mark when starting my macbook after a few minutes it shuts down, any ideas??

When turned on our Macbook flashes a folder with a question mark in the center screen, then it shuts down after a few minutes. Doea anyone have any ideas how to boot the computer back up?
Cheers

That folder with the question mark icon means that the MacBook can't find the boot directory. That can either mean it can't find the hard drive or the Operating System data on the hard drive is somehow corrupted.
Put your install DVD into the optical drive and reboot. As soon as you hear the boot chime, hold down the "c" key on your keyboard (or the Option key until the Install Disk shows up). That will force your MacBook to boot from the install DVD in the optical drive.
When it does start up, you'll see a panel asking you to choose your language. Just press the Return key on yourkeyboard once. It will then present you with an Installation window. Completely ignore this window and click on Utilities in the top menu and scroll down to Disk Utility and click it. When it comes up is your Hard Drive in the list on the left?
If it is then click on the Mac OS partition of your hard drive in the left handlist. Then select the First Aid Tab and run Repair Disk. The Repair Disk button won't be available until you've clicked on the Mac OS partition on your hard drive. If that repairs any problems run it again until the green OK appears and then run Repair Permissions.
If your hard drive isn’t recognized in Disk Utility then your hard drive is probably dead.

My Intel iMac only shows a blinking folder with a question mark when powering it up. What can I do besides running the hardware test of the original installer disc.

My Intel iMac only shows a blinking folder with a question mark when powered up.
I did run the hardware test of the original installer disc and no trouble was found and I am out of options. Does anybody have any advice what to do next

If the drive shows errors then repair, if after the 3rd pass of Repair Disk in Disk Utility it still shows errors it's telling you it's time to be replaced. Take it to your local Apple Store or AASP for repair, when it comes back use your backup (either Time Machine or bootable clone) to restore so you can pick up where you left off.

TS1440 Flashing question mark when I start the MacBook

Hello!, I have a MacBook Pro but there was a flashing question mark when I start the MacBook, it does not go away, I have read the tips on you all site, but I can't find anything, it is for the Mac, not for a MacBook. Can anyone help me please?? Thanks!

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 one or more of these:
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.
Note that the information I have provided is what Apple recommends, If other users suggest different solutions than found here, then be sure what they recommend does not impact on your warranty, if any, or ability to get continuing Apple service.
Please don't start removing drives or changing cables unless you know what you are doing and have exhausted other non-invasive alternatives outlined here. If you perform any work yourself that is unapproved by Apple, then you will void any warranty you may have and lose all further Apple Support.

Mac Mini with A Blinking Folder and a Question Mark on it YAY!!!

ok I just came into work today to see that one of my Mini Macs has folder with a Question mark on it and i tried to put the OS 10.2 disk in to try and do a reinstall and can't get it to do anything and now can't get the CD back out lol I think i need to take a hammer and just break this thing or just let it be my paper weight. any help would be great thanks
Cliff

The flashing question-mark indicates the system can't locate a valid MacOS copy to boot from, which in turns would indicate there is likely to be a problem with the hard drive. It may be that the drive itself has failed or is failing, but it could also be that there is some data corruption or a problem with the drive's directory or data structure which prevents the system finding the MacOS install on it, or from reading it.
In this situation, booting the system with a valid install disk, and then using the Disk utility copy on the installer to check the drive and attempt to make any necessary repairs is the right place to start. If that doesn't work because there are problems which Disk utility can't fix, then either a good commercial utility such as Disk Warrior is needed, or the drive can simply be wiped and MacOS installed again in an 'erase and install' to get the system back into service.
However, the first step is to get the 10.2 disk out and a valid installer in, and to check the internal drive for errors.

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.
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. 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.

White screen with a folder and a question mark on the folder and its blink?

I was on my computer and it was basically frozen so I turned it offf manually. Then I tried to turn it back on and it it made the noise like it was turning on, but then there was a white screen. Then I turned it off again and it did the same thing exept that now it has a little blinking folder with a question mark in it. Then I turned it off again and it did the same thing as it didi the 1st time......HELP ME !!!
(oh now it just turned itself off)

You can try starting up while holding the 'Option' key down. This will hopefully present you with your drive to select from. If not, insert your Install DVD and restart with the 'C' key down. This is called booting to the DVD. When the topmenu appears, launch Disk Utility and then verify/repair both permissions and the drive itself.
If the drive does not appear in Disk Utility ...you may have one of the faulty Seagate drives. If you are still within you standard 1 year warranty (or have Applecare) then that drive will be replaced.
Do you have things backed up?
