Dead mac side, live windows

[boredrex]

Someone pulled the plug on my iMac one night, and I guess something happened, because after that the computer would no longer boot into my Mac partition. However, I have no issue getting into my windows partition.

I installed a new HD on my fiances macbook pro, and using the enclosure and her old hard drive, I've manage to boot up on Mac, albiet via USB. I attempted to repair the disk, but it just won't go. I've even tried to reformat the disk and do a clean install on the whole hard drive (which I'm fine with), but this didn't work either. If I try to reinstall OSX, it doesn't recognize the HD in the iMac.

2010 iMac 27" screen core 2 duo or something along those lines. thanks for any help

Hello and welcome.

If the iMac was running when the plug was pulled it could have corrupted the HD which would cause booting issues. If it was accessing data at the time, actual hardware damage could have occurred and fried the HD.

If I follow you, you can boot the iMac using a USB HD (from the MBP), correct? If so, the iMac hardware itself is OK and the problem lies with the iMac HD itself.

1. When you tried repairing the HD (using Disk Utility I assume), did it give any specific error?
2. Have you tried erasing the Mac partition?
3. If you don't need any of the files from the Windows partition, you could reformat (partition) the entire HD and try again.
4. Do you have any third-party drive utilities like DiskWarrior, Drive Genius, TechTool Pro, etc?

1). Disk repair begins analyzing the disk, but does not start, even when I let it go one night.
2). Cannot erase the Mac partition or the whole Hard drive. it just doesn't start. I've even tried doing it from within windows and from within my external boot USB
3) answered above
4) I have tech tool pro I think.... what can it do?

If you have a TechTool Pro disc, you could boot from it and run a surface scan of the HD. If that fails immediately as well, then it is probably a failed HD. It is possible that it is an internal cable, but not as likely. Are you close to an Apple Store or Apple Authorized Service Provider?
