Can not access to admin account / guest account status only safari safe mode / no access to utilities nor HD nor disk change settings options (VERY URGENT)

Hi, i will appreciate your advice and support

It is very urgent, all my work is there and much data i did not back up

Brief review:

STATUS:

When log in no access to admin account

REVIEW:

I intent to login:

i turn the mcbook air on

login options appear: admin user / guest user

I choose admin user

imput password, enter

the screen stay in grey, with a round sign that shows normally processing (wait time)

Then nothing else changes, not dark screen, nor access to admin account, nothing, just that last screen with the round sign

If i log in to the guest account following takes place:

it appear a warning "!" within a triangle: the guest user in safe mode only safari

Then i access a screen black with only safari function

have no access to files, system, utilities, nothing

only possible to wifi access or network.

BACKGROUND REASONS

No idea

But i remember i did do some change in hard disk settings, limiting access to external users to it. I am not sure really what i did click on, i was waiting for a download while i checked the free space on disk, and noticed one could limit access to it to admin only, some users and external users, i decided to limit external users.

Then the whole hanged out

I had few times this hang out experience with the very new (less than one year macbook air)

When i did reset by pressing turn on/off button

and try to login again

got the results described above.

PROBLEM SOLVING

Try to CMD-R and CMD-V, nothing changed

and could not find in the community any advice

GRATEFUL FOR YOUR ADVICE AND SUPPORT

If you want to preserve the data on the startup drive, and it's not already backed up, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data, you can skip this step.

There are several ways to back up a Mac that is not fully functional. You need an external hard drive or other storage device to hold the data.

1. Start up from the Recovery partition, from Internet Recovery, or from a local Time Machine backup volume (option key at startup.) Launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.

If you use FileVault 2, then you must first unlock the startup volume. Select its icon ("Macintosh HD," unless you gave it a different name.) It will be nested below another disk icon, usually with the same name. Click the Unlock button in the toolbar. Enter your login password when prompted.

2. If Method 1 fails because of disk errors, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.

3. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.

4. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
