arduous drive – Query Mark on 2015 Macbook Professional — any hope saving knowledge (and MBP)?

My 2015 Macbook Professional 13” (OS X 10.11.6) is refusing to activate and retains exhibiting me a flashing query mark 😭.

I’ve adopted the Apple Help directions right here, however was unable to repair the issue. I additionally didn’t have any luck with a NVRAM reset. I sadly don’t recall the final time I backed up the pc, which is totally my fault. The laptop computer was working completely fantastic up till now. I hadn’t turned it on shortly and aside from operating out of cost shortly it was completely good.

To date, I’ve succeeded in going by way of Web Restoration, however after I try to “restore disk,” I get an error that claims “Partition map restore failed whereas adjusting buildings to suit present entire disk dimension” (see picture beneath).

My questions are:

1. Is performing a Goal Disk Mode Switch the perfect probability I’ve to again up my knowledge?

2. Is there something I can do in terminal to handle the restore error? I included an image beneath of what got here up after I typed the diskutil command. I am not tech savy honestly, however can comply with directions if that counts. Tried to comply with this tutorial, which succeeds in resolving the disk utility restore error message by manually utilizing fsck_hfs / sck_hfs -rc -d /dev/diskXsX. I ought to notice that was additionally unable to mount MacintoshHD (choice on the prime of Picture #2 was not clickable).

Thanks prematurely for any recommendation or ideas you will have!
