Installed ssd on new macbook but getting a grey folder with a question mark?

Hi, I bought a new macbook pro, late 2011. Installed aftermarket SSD myself. Switched mac on and i get a question mark in a grey folder with a white background. I rang Apple and they said they mac cannot find the operating system.
Any help?

You have to install OS X on the SSD in order to use it. Start with:
Drive Preparation for Lion
1. 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. 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. Once formatting is completed quit DU and return to the main menu. Select Reinstall Lion and click on the Continue button.
The installation is done via the internet so you will need an active network connection which can be wired or wireless. The installation can take several hours.

MacBook Pro gets a flashing folder with a question mark

I start up my computer and I get this flashing folder with a question mark. I looked up on here how to fix it but I get lost when I get to the disk utility part. All that shows up is something called disk0 and below it it says Mac OS X Base System. I click on it but the repair disk button is greyed out. What do I do? Please help!

The MBP cannot find the OSX. It may be a HDD or HDD connection problem.
Start your MBP with the OPTION key down. Select the recovery partition. From the 4 option menu select Disk Utility.
Select Disk Utility>First Aid and run Verify and Repair.
If successful, you should be back in business. If not, the HDD may be faulty.
Ciao.

Welcome to Apple Support Communities. We're users here and do not speak for "Apple Inc."
Power on the computer and insert the DVD immediately.
Hold down the 'C' key to boot from the Snow Leopard DVD.

After selecting the appropriate language, if necessary, select Utilities, and Disk Utility.
You'll likely need to partition and format the new drive before it's recognized.

I just bought my MacBook Pro 13" and I tried to install an anti virus but then it went into a grey folder with a question mark I need help with restoring the iOS please

I need help taking out the grey folder with the question mark and I've try everything except the CD thing because my MacBook didn't come with one so I really need help please

What anti-virus software did you install? Although there's a lot of bad anti-virus software out there, no anti-virus software should cause such a problem. A gray screen with a flashing question mark on a folder means that no bootable system could be found, which means that the system was badly damaged or corrupt. Even installing bad software would not normally cause that, so either there was something badly wrong with the system already or the anti-virus software you tried to install was really, really bad!
As mende1 says, you need to reinstall the system at this point. After your system is back up and running, read my Mac Malware Guide. If, after reading that, you want anti-virus software, use one of the programms recommended in that guide.

My MacBook Pro turns on but not all the way, it gives me an icon of a grey folder with a question mark in the middle, and won't go further that that. Anyone knows why, or what's the problem?

If these do not resolve the issue or if you are not comfortable with proceeding through these steps then take your Mac to an Apple store or an Apple Authorized Service Provider. An Apple store will perform these initial steps, diagnose the problem, and give an estimate for repairs (if needed). If the Mac is less than one year old or is covered by AppleCare any repairs would be free.

I have a problem with lion. My MacBook pro froze and now I get a gray folder with a question mark.

I recently upgraded to lion but my screen just froze. I had to shut it down by holding the power button down. Every time I tried to start it again I got a grey folder with a question mark and couldn't do a thing. I' ve been told to restore snow leopard but I dont want to loose my files or email. What can I do?

Boot from your recovery partition. Check and if necessary repair your startup volume with Disk Utility. You may need to reinstall Lion.

When I start my Mac air I get a flashing folder with a question mark

I am trying to start my Mac air and I get a flashing folder with a question mark. When I turn the power of it shuts down but wen starting it comes back

Just being clear about your situation. When you hold down Option during boot it does not show a system volume or a recovery volume from which to boot. At that point if you select a network boot and you do not see a spinning globe that persists there a good while as it loads the recovery partition over the network. True?
A couple of more thinks to try:
Disconnect all of your external devices.
Reset PRAM
Boot with the option key again.
Standard things to try (which is sounds like you already have attempted) A flashing question mark appears when you start your Mac

If no Volumes are shown, it is telling you there are no potentailly bootable Volumes attached. That means your boot drive has died or the bootable image on it is unrecognizable.

When i boot i get a flashing folder with a question mark. disk utility doesnt work or read my harddrives to boot with. i installed a new SSD and its not reading that either. i have a macbook pro 2011, any help?

So I came to this problem a while ago. M ycomputer basically froze so I was forced to shut down by holding the button down. When I started it up I got the flashing folder with a question mark. I started it up holding down the command and r keys which brought me to disk utility. Although my computer doesn't read that I have a hard drive to start it up. When I click on the disk utility app, I cannot verify or repair anything either. The buttons won't allow me to click on them. It also shows "Mac OSX Base System" which shows I have files and what not saved. I had been told that I need a new hard drive so I bought and manually installed a OWC SSD 240GB drive and when i booted the computer up it booted up yo the operating system fine with all my files and what not on there. After about twenty minutes, it froze again. I forced a shut down, restarted and the same thing happened. I am not able to choose my SSD to boot up, although thats probably because it doesn't have an operating system installed on it??
i have a Macbook Pro 13" 2011
any help would be great, I'm overall confused.

ryansaint11,
this isn’t Apple support; this is a user-to-user forum. We’re just fellow users of Apple products here.
If you want to boot from your SSD, then you should put the SSD where your HDD currently is, and put the HDD into the optical bay. (That setup will also get you the best performance.) At the moment, you’re still booting from your HDD. Note that you will need to format your SSD in Disk Utility [with the “Mac OS X Extended (Journaled)” format] so that you can install OS X onto it.
Since you have an Early 2011 model, it might or might not have originally come with grey installation DVDs. You will be able to find out whether it did or not by trying to use OS X Internet Recovery to install OS X onto your SSD. If it does not work, or if the installed OS turns out to be Snow Leopard, then it will have originally come with the DVDs, and you should purchase a replacement pair of DVDs from Apple or iFixit; those discs will have your MacBook Pro’s Apple Hardware Test and its iLife apps. If the installed OS turns out to be Lion, then it will not originally have come with the grey installation DVDs, and your Apple Hardware Test will be installed along with Lion, and your iLife apps will be downloadable from the Mac App Store.

Instead of an apple, I get a file folder with a question mark!

Hi. I turned on my MacBook today, and instead of the apple popping on to the screen after a few seconds, I got something that looks like a file folder with a question mark in the middle of it. Then it starts to flash! Turned it off with the power button, tried again a few times...same result. Anyone know what to do? Thanks

If the computer starts up after a brief delay, you probably just need to reselect your startup volume. Choose Apple menu > System Preferences. Click Startup Disk and select the the desired startup volume.
If your computer does not start up, try repairing your startup disk and reselecting your Mac OS X startup volume. Click the link below for the webpage with detailed instructions.
A flashing question mark appears when you start your Mac

Getting a flashing folder with a question mark when starting Imac.

I got this flashing folder with a question mark on it when starting my Imac this morning. Im running on Osx 10.6. I put it in target disc mode and connected it to my macbook pro. I opened the disc utility app on the macbook and found my imac. I "verified" it and found an error. When I clicked "repair" the disc utility app froze and crashed. When I opened it again my Imac didn't show up. I've restarted both computers several times with no luck. Whats my next step?

Hi.
Try restarting your iMac while holding down the option (alt) key until the spinng gear appears. You should momentarily be presented with a list of startup drives to select.
Choose Macintosh HD (your normal startup disk drive) and click the right-arrow.
When your iMac boots, go to System Preferences > Startup Disk and again select your normal startup disk. Then click Restart.
I hope this is helpful.
EDIT - disconnect the machines from each other first.

MacBook Air won't boot up and all I get is a folder with a question mark

My 2012 MacBook Air running mountain lion won't boot up, all I get is a grey screen and then a folder icon with a question mark in it. What can I do?

Welcome to the Apple Support Communities
It's possible that your hard drive has stopped working. Do you remember what OS X version you were using?
If your Mac came with DVDs, insert the Mac OS X Install Disc 1 and hold the C key while your Mac is starting to start from the DVD. Then, choose your language, and go to the Utilities menu (on the menu bar) > Disk Utility. After that, choose "Macintosh HD" in the sidebar and repair the drive. If it couldn't be repaired, you need a new hard drive, and you can do it yourself if you want. If you don't want, take the Mac to an Apple Store or reseller.
If your Mac didn't come with DVDs, follow the same steps but holding Command, Option (Alt) and R keys while your computer is starting

When turned on MacBook a icon of a folder with a question mark in it keeps flashing, what does this mean?

MacBook turns on but doesn't go to home screen, instead a folder icon with a question mark on it keeps flashing.

It means that your mac is unable to boot, try doing a safe boot http://support.apple.com/kb/ht1455 first, if that does not work insert your OSX disc (the one that came with your mac) and boot to that, post back with a report.
Is your backup 'bootable' (Carbon Copy or SuperDuper) or non-'bootable' (Time Machine)

Why do I get a blinking folder with a question mark after remote locking my Macbook?

Hi,
I wanted to try the remote lock feature of iCloud.
I remotely locked my 17 inch Mid 2009 MacBook Pro. I received the confirmation email stating that the machine had indeed been locked.
When I went to the machine to unlock it, I was surprised to see a grey screen with a blinking folder. I had expected to see a place for me to enter my PIN. Rebooting the machine revealed the folder again.
What is going on? Did sometihng go wrong resulting in my somehow wiping my hard drive?
Thanks in advance for any help on this.

Here is the email:
Doulos has been locked.
Doulos was locked at 4:40 PM on March 11, 2012 with the following message.
“Remote Locked!”
If you retrieve your Mac, unlock it using the passcode you created to lock your Mac.

HELP I'm getting a blinking folder with a question mark at start up? Have been trying to fix this for 3 hours and I dont want to lose all my files by resetting it completely!!

I currently have Mavericks but my original OS X disk that I have I'm pretty sure is Mac OS X 10.6.6. I'm not great with computers but am usually able to fix problems I have had with mine in the past. I have reinstalled and reset my computer to factory settings before, but I am locked out of my computer completely & can't get to my files to save them & I really dont want to lose them. I was in Safari earlier opening a file, the page started to not respond & froze up my whole desktop so I did a hard shutdown & restarted my computer. I haven't been able to get back into my account ever since. If my only choice is to lose my files & reinstall everything, I need detailed instructions because I actually attempted to do this at first, out of desperation to fix my computer & the installer was asking me to select what disk I wanted to reinstall lion to yet I dont have a disk for that nor do I know what it exactly is asking of me? Please help

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 or globe 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:
a. Problem with the computer's PRAM - See Resetting your Mac's PRAM and NVRAM.
b. Boot drive's directory has been corrupted - Repair with Disk Utility.
c. Critical system files are damaged or deleted - Reinstall OS X.
d. 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.
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. Simply boot from the Recovery HD to perform the above.
Reinstall Snow Leopard 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.
Download and install Mac OS X 10.6.8 Update Combo v1.1.
Reinstalling Lion/Mountain Lion Without Erasing The Drive

(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.
