Macbook Crashed (Urgent Help, School related)

That means the system is unable to find the OS. Did the 2011 come with install discs or is there a recovery partition?

 

Run it into Apple but I hope you have a backup. There is really nothing you can do without a recovery partition or install discs. If the OS cannot be found, that's all I know to do.

 

Try this, hold the Option key at startup until the boot manager arrives, see if your Macintosh HD is there, click on it and see if this works.

Sometimes but rare the Volume looses it's blessing, if that is the case you'll see the question mark.

 

The disk should repair/run fsck when started up in Single User mode, you can do so by holding Command-S at startup.

You could also do so by entering:

fsck -y

in Single User Mode.

 

Is the machine your posting this from a Mac? If it is, then you can try booting the dead macbook in target disk mode to recover your files...

 

You choose to try to repair the Recovery HD which you are starting from, you can't do that, also, your HD is not visible.

You should try what I said above in my last post.

Edit: Click on Disk0, see if the repair button is available when you choose it.

 

What? Did it just die or...

 

Sorry, It can't be dead, you are running Recovery HD from the HD, read my edited above post.

I edited My post, you didn't see I said it was dead, but it can't be dead because he is running it from the Recovery HD

 

I already "told" you this two times, see below.

 

sounds to me its the boot record..

The way you describe it, it sounds to me like the system or yourself has somehow shot the boot record. Now your system cant find the OSX any more and you can not boot at this moment.
It looks like you have no hardware problem and the HD is ok.
If you had the original disk you could repair your system. Without it, it is difficult next to impossible without any backup or disk or apple store, assuming you have no backup partition on your hd or any other external hd.

If you have a second computer, (obviously you have posted here) you can go and search the internet to either buy a new OSX disk replacement at apple, look on ebay, craigslist or you use "other" sources.
I have heard rumours, there are rare cases of people, that put OSX images on torrent platforms...
If you consider that, you would still need either a double layer DVD or a USB Stick with 8GB or more to perform a new installation using the repair option during the installation process. It can be tricky though, because you would need the exact same OSX version you are using right now.
Make sure you do your homework on google reading, before you start installing a new osx. Check out youtube as well, many DIY videos on how to recover OSX...

Good luck to you!!!

 

The OP said he has a mid 2011 MBP, which does not exist, if it is late 2011 his MBP did not come with disks, if early yes, they did.

----------

No, you did it right, it's the Command and S button, hold as long as a black screen arrives with text, but if that is what you did then there is no reason to do it again.

Edit: Which model do you have, a mid 2011 MBP does not exist.

 

If you click on disk0, what info is there on the disk, like to know how big it is, if its near to what your HD capacity is then for sure the HD is not dead.

I have seen this before and it seems to be hard to get out from.
Maybe an Internet recovery will work, Internet Recovery is different from Recovery, Hold Command-Option-R to get into IR.

 

I had this exact problem last year with my mid-2009. It could be the hard drive cable. If so, then your data is still there, and nothing is wrong with your hard drive. Get it to an apple store or an authorized service provider and they can fix it right up

 

This can not be the cable, he is starting up from Recovery HD which is located on the HD.

 

I was referring to the original issue with the question mark folder on startup. I had the same issue after a hard restart. Basically the hard drive and the logic board aren't recognizing each other. A new hard drive cable will fix that, at least it did for me.

 

You don't seem to understand, he started from Recovery HD which IS located on the HD, if the cable was broken he CAN'T startup from Recovery HD!

 

I am answering the ORIGINAL post. Before OP tried to access the recovery HD or anything. I had this exact same issue. The logic board is unable to access the hard drive because something has happened to the cable in the hard restart. Apple was able to fix it by replacing my hard drive cable. Please, OP, get it to an Apple Store or an authorized service provider, and I promise that unless something else is wrong this is a very easy fix. They fixed mine except for an underlying sleep issue that caused me to restart it. Have them look at that freezing issue while you're at it.
