Macbook Air black screen with loading at startup

[mawt1]

Hello,

Here is the problem on video :

As you can see, after the log in in the first white page, I have the small loading bar circle working. After some seconds it turns off and I have a horizontal bar on the top left that appears really fast. After there is just nothing and the bar circle working icon come back and the same story repeats itself.

What I have tried and it does not work:

- Cmd + option + P + R at startup. It will restart again and do the same problem
- Start in safe mode, it will do the same thing
- Cmd + R and execute the First Aid in the disk utility noting happen, like if the disc is normal.

If someone can help me that would be really appreciated...

Thank you!

So it lets you go in to the Recovery mode ? Did you try the Internet Recovery

Thank you for your response!

So I try the Internet Recovery and just after the download and selected my HD, it says that I don't have enough space... I remember that I have some big video files that I wanted to delete...

So I tried to delete these files with the Terminal. I saw on the Internet these codes to navigate into my files:

cd /Volumes/Macintosh\ HD/
cd /Volumes
cd ~/Desktop

none of these codes works the all gave the message "No such file or directory".. (there is also "-bash-3.2#" before I can write something in the Terminal. I guess it is normal).

Also, I cannot eject the OS X Base System in the Disk Utility..

Do you know what I can do?

Thank you,

Martin.
