rMBP 15" purchased  two weeks after release last year.  This weekend I got the grey screen with a folder and a ? icon.  I'm a new Mac guy so any tips on how to troubleshoot this (safe boot, etc...).  Any way to retrieve data?

MacBook Pro with Retina display, iOS 6.0.2

    Reinstall OS X:


    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.

    It shows that your computer can't find any bootable volume to start. In most of the cases, that's because the hard disk is damaged.


    Your Mac has got Internet Recovery, so press Command, Option and R keys while your Mac is starting to start into OS X Recovery. Then, open Disk Utility, select the hard disk in the sidebar and verify the disk. If it finds a problem, repair the disk, and if it can't repair the disk, take the computer to an Apple Store.


    If it doesn't find any problem, open  > Startup Disk, choose Macintosh HD and restart. If you don't see Macintosh HD as an option, reinstall OS X on the computer

    You may try some of the suggestions here, but you best option is an appointment at an Apple store genius bar.  Use your warranty.

    Thanks.  I'll look into these tips.  I think the Genius bar might be the answer for this new Mac guy.
