there is no way to boot from a USB or something? before i loose all the info?
You can definitely try booting from a Linux Live USB or similar to transfer important data off before reinstalling. (And, make sure to set up Time Machine next time!)
You would have been running OS X 10.11.6 (El Capitan), so you can try booting to the recovery system, where you could reinstall the system you presently have. You can also try using Disk Utility, to run First Aid on the hard drive (might help) -- But, yes, Wowfunhappy has a good idea to do first, if there are important files on that 2012 MacBook Pro, and you don't have any backup of those files.
Do you know if the drive is an old hard drive (with a spinning disk), or do you know if the original hard drive has ever been replaced with an SSD? This would be the time to swap out an old hard drive to an SSD, as the old drive may be close to failure

Before an Erase and Reinstall, would it not be possible to put the Mac in Target Disk Mode and then grab the data off the drive? Or do you guys see something in the picture that says this Mac cannot do TDM?
I mean, at least if OP could copy the data off that before wiping the drive, that'd be a good thing I think.
I've found over the years that Carbon Copy Cloner has the best utility for my particular setup workflow, while Time Machine has the worst or is simply unusable.
A few months ago my primary SSD failed. This is on a system that had OCLP installed. I had a CCC sparseimage and simply restored that image to a new SSD, then used a OCLP USB stick to reinstall the OS. My system came right back up with all my data, preferences and whatnot intact.
This was possible because I maintain a daily backup to my NAS of ALL my Macs and a weekly back up to Dropbox. All of these are sparseimages which are self-contained and easy to move. Unlike sparsebundles, particularly those that Time Machine creates and are nigh impossible to move, which also force a full drive backup when you do successfully move them.

Or maybe just a backup in general, not necessarily Time Machine?

Yes, of course! Time Machine just so happens to be very easy to set up on macOS (assuming a simple setup where you have a computer and a USB hard drive), so I feel if I suggest that, people are more likely to actually do it. 🙂
(Well, just copying files is arguably easier, but then you don't have an incremental backup.)
