Q: El Capitan Won't Safe Mode

So, when it was on the installing process, it was stuck at 19 minutes. I waited 3 hours for it. I decided to shut it off by pressing the power button instead. When I turn it on, entered my password a weird message appeared on my upper right of the screen. I went into Recovery mode, yes, I can install a new OS X. The problem is, I have to delete some files the suggestions are to go on Safe Mode. It's been hours and I've tried all the possible "safe mode" options. Pressed the shift key, while the start-up sound was playing, after, and before.

I have 5 papers that are due this week, please help. D: THANK YOU!

MacBook Pro, iOS 9.0.2

Hello, thanks for the reply. I did not understand the fsck part (I've been thru the Recovery mode - disk utility is okay). Part of the message that appeared in my screen, by the way, is mac os: not yet set.I guess that's what's causing this trouble? Is there easier ways for me to access my files? D:

if all else is failing to into recover mode and check the integrity of this disk.
In other words what you're doing now is where I'd be looking to verify or rule it out too.

you can use disk utility from recovery mode
OS X: About OS X Recovery - Apple Support
CMD+R at boot, then select Disk Utility, select your boot drive, select "first aid" and do a "repair disk"
in the event something is found the Disk Utility will attempt to repair it.

if you have another mac you can by using target mode provided the two computers have matching FW400 or FW800 or Thunderbolt connectors, a spare cable or a FW to TB converter*

I have the same problem initiated when El Capitan just hung after a forced startup. I have tried recovery and Disk First Aid - showed no issues. I also cannot access permissions repair in El Capitan. I have reloaded El Capitan 3 times now (works for a while the just gets to a point where it just hangs after startup again) and now want to go back to Yosemite which I have on a usb drive but am finding that difficult. El Capitan will not allow me to load an older version of OSX. I have another mac but have to wait till I get a cable which will connect thunderbolt to firewire 800, or can I do that with an ethernet cable?

I don't think ethernet is supported for this but there is an article here that might help:
