How To Install Diskwarrior On Usb

There is not much you can do with a stock Mac to fix the hard drive. You could plug the hard drive in another Mac (as a secondary drive, not a boot one) and see what Disk Utility tells you (press command-space then type Disk Utility to launch it) about it but it's not guaranteed to help you much. I am not even sure it can correctly repair a boot hard drive.

Your best bet is using a disk repair program such as DiskWarrior. It costs a bit but has a very good reputation and saved many damaged hard drives. Cf for a great example of it saving important data. Windows had changed the HD partition map from GUID Partition Table(GPD) to MBR. And made HD a 'dynamic disk'. This is why Mac Os wasn't able to boot. So, I've tried 1001 ways to recover.

Nothing worked. Interned Recovery gives -2002F error. Macbook pro 2012 can't boot from bootable DVD to use DiskWarrior, Drive Genius or similar.

It can't boot from OS X Lion install DVD. I could boot Windows recovery console and tried TestDisk which failed to write something to HFS+. Also tried some Windows third party applications which also failed. I asked a friend with latest Mavericks(which I had too) to make a Recovery USB using and make a DMG file from it using Disk Utility and send me over internet.

Then I used the application under Windows and burned DMG on my USB stick. I was able to boot from this USB stick into Recovery Mode and from there I can reinstall Mac Os X Mavericks. Somehow it sees my Ethernet cable and doesn't give error. Note: that Disk Utility wasn't able to recover partitions. I tried to run DiskWarrior from terminal but it gave me an error. TestDisk didn't run too.

I could recover or backup my files using, but there was no need since it's my new macbook and I didn't have much files there. I made a clean installation on a USB stick and run DiskWarrior and Drive Genius, none of them could fix partitions. So I gave up and reformatted HD. That's probably not the answer on how to fix partitions, but that's how I solved this. If somebody finds a way to fix partitions please post as an answer.
