my getting some problems, I used the first method to make the mac hd partition active again but it won't mount in disk utility and in the bootloader both drives show up as "Windows NTFS" and one will boot to windows but the other just restarts the system.

edit: lucky I made a backup of the mac os partition, I just restored that and it was up and running again.

...so now i know... Windows system image back up WILL kill OS X dual boot. Strange.

Glad to hear you worked it all out.

Cheers.

it wasn't the image back up that killed it, it was changing the active partition to windows in the first place.

That alone won't do it. I've done that myself plenty of times. Something else must have happened that formatted that partition to ntfs-- as you said it showed up as ntfs after you used image back up.

btw I used repair disk permissions in disk utility as they were messed up and it worked well. Also installed the security update 2011-002 without any problems.

Thanks.

The most likely problem here is that the Win 7 partition is still set as active.

Your Win 7 partition is damaged. You can attempt a fix, by following post #40 on this thread.

Once you've repaired win 7: set your OS X partition as active, follow the instructions here (you'll still need your OS X install USB to use as a bootloader.): http://www.insanelymac.com/forum/index.php?showtopic=22844

After you make OS X partition active, run NBI checking only "install chameleon bootloader."

Provided you are able to repair Win 7, and follow these instructions, all should turn out fine.

Cheers.

Hi Oscar,

Thanks for your suggestion, now I can boot from dell mini, after I install NBI to my mac os partition.
