Hello all,

I installed Win 10 on a 2012 MBP 13" using the built in Boot Camp utility, OSX El Capitan. Everything went fine, I've done this dozens of times for many, many computers. After installation, everything on Win side was working perfectly, installed all drivers and went to reboot to finish installation. That's when things took a nose dive.

At this point, neither windows or OS X are showing up when I try to choose a boot device. I pulled the HDD and plugged it into my Linux machine, it recognizes the drive is there, but will not mount it. I went through all of the recovery utilities in Hiren's, still nothing.

I was finally able to get into recovery mode on the computer (this took several attempts) and went into disk utility. This is just showing the HDD with a name that looks like the HDDs hardware serial #. The partitions are still there, but they all (3 of them) are showing as "MS-DOS FAT". At no time did a reformat any HDD, especially to FAT32.

Couple of questions:
1. Out of morbid curiosity, anyone know how this happened???

2. I'm good with a lot of programs, but sector by sector data recovery is not in my wheel-house (I'd be making way more money than I am if it was). Anyone have any suggestions on being able to recover this data (I've tried all the recovery tools baked into Hiren's Boot CD).

Thank you all in advance for any help you can send my way!

Hirens is designed for use with an MBR partitioned disk, not an OS X partitioned one. I should think that using these "recovery" programs on your OS X disk has now corrupted it beyond recovery. Your best bet is to start over; repartition the disk on your Mac and reinstall your operating systems. And don't try to use non-Mac utilities on a Mac disk in future.
 
McHenryB,

Thanks for the feedback!

I figured Hiren's wouldn't do anything for OS X, but nothing was reading the drive at all, so I gave it a shot. It wouldn't even see anything in the Windows partition, so I'm pretty certain something major happened when it went down. The only recovery tools I used were the stand-alone "Live" Linux ones, not the Windows recovery tools.

Fortunately I back up pretty regularly, so it's only about a weeks worth that I'm losing. I just wanted to ask to see if anyone has seen anything like this before, like I mentioned above "morbid curiosity".

Thank you!

Mike
