OK, now I've got the picture. Here's what you can begin with:

 

Repair the Drive for El Capitan

 

  1. Restart the computer and after the chime hold down the Command and R keys until the Utility Menu appears.
  2. Select Disk Utility and press the Continue button.
  3. Then select the indented (usually, Macintosh HD) volume entry from the the side list.
  4. Click on the First Aid tab in the toolbar and wait for the Done button to activate. Click on it, then quit Disk Utility.
  5. Select Restart from the Apple menu.

 

If First Aid doesn't fix the problem for you, then you will try this next:

 

Reinstall El Capitan Without Erasing Drive

 

       Please be sure you back up.

 

  1. Restart the computer. Immediately after the chime hold down the Command and R keys until the Utility Menu appears.
  2. Select Disk Utility and click on the Continue button.
  3. Select the indented (usually, Macintosh HD) volume entry from the the side list.
  4. Click on the First Aid icon in the toolbar. Wait until the Done button activates, then click on it.
  5. Quit Disk Utility and return to the Utility Menu.
  6. Select Reinstall OS X and click on the Continue button.

    You cannot boot from the Trash. You have to have a system installed on the drive from which to boot. So, I have no idea what you are doing nor why. Your profile says you are using Mountain Lion. Is that correct? If not what are you using?

    You must have booted up already or you would not have a trashcan, explain what you are trying to do.

    I was using slang lingo for the model of my Mac Pro.  The "trashcan" model as opposed to "cheese grater" Mac Pro. My 2013 MacPro... black cylinder model... will not boot up. It starts up w a black screen, goes to Logo, then starts progress indicator... gets about a quarter of the way and then shuts down.  Tried many safe starts no go.
