what does
after holding option key i choose the only one option there - internet recovery (or something like that); after this (~30 minutes) it prompted:
apple.com/support
-2003F
The main problem is appearing blinking question mark against the background of folder (this problem disappears after a long time working of mac)
I cannot find a definitive description for the error, but it is an Internet Recovery error of some kind. Be sure you have disconnected all external peripherals except the Apple mouse.
I would attempt to boot from your Recovery HD. Using network recovery should only be attempted if you don't have a Recovery HD:
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 arrow button below the icon.
What is it you are attempting to do and why?
as i said in my second message in this topic, i have a big startup's problem with macbook air md760; sometimes it's loading properly, sometime fails; i don't know the the cause of it, but i think it's hard drive issue (when i load disk utility it doesn't detect any ssd on mac)
this problem reproducing after long time shutdown of mac
Try this:
Resetting your Mac's PRAM and NVRAM
Intel-based Macs: Resetting the System Management Controller (SMC)
Reinstall Lion, Mountain Lion, or Mavericks without erasing 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
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 then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu.
Reinstall Mountain Lion or Mavericks
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
Note: You will need an active Internet connection. I suggest using Ethernet
if possible because it is three times faster than wireless.
Thanks for tips, i wiil try them now
I've done everything from your tips; first of all, if i have a startup problem "Resetting your Mac's PRAM and NVRAM" helps only for a shirt period of time, but after 30 minutes same problems appears again; second, i reinstalled OS and now everything is fine, I will report if there are any problems appear again.
P.S. sorry for my bad english!
please, give me advise. What if my problems with mac appear again, does it mean that problem is in hardware?
SOLUTION
I had the same issue. You just have to keep trying to restart in recovery until the error goes away. This happened to me because I restarted the computer after wiping the drive.
