Title: Think I wrecked my mbr or something!
Post by: stephen_falken on April 19, 2010, 12:16:46 PM

Hi all.

I had a great working setup of Chameleon with Windows Vista, Leopard, and Snow Leopard.

Anyway, I was messing around with the chameleon themes and somehow managed to stop the system from booting.

I didn't think this would be much of a problem, so booted windows CD and used Diskpart to set my Leopard partition as active. This didn't work, so I repeated the step this time with the Snow Leopard partition, which didn't work either.

Finally I put in my external HD which has Chameleon loader on it, and the OS selection screen is showing all my partitions as being NTFS!?!? Can't understand what happened here as all I did was use Diskpart to set them active.

When I boot the SL installer and goto Disk Utility, only my Vista partition is mounted, the other two are still showing as NTFS but will not mount.

I can still see the contents of both partitions from windows using MacDrive. Please help, how can I fix this as I had almost a 100% setup on my laptop and spent so much time on it I am severly depressed about this!!

Any help appreciated.

Thanks

You could try to repair your mbr by creating a boot cd or usb thumb drive of either partedmagic (http://partedmagic.com/download.html) or sysrescue (http://www.sysresccd.org/Download). and use fdisk (or gdisk if your disk is gpt) to change the partition types back to hfs+ in the partition table.

It would be a good idea to backup the mbr before you start too  ;)

Hi and thanks for the reply.

I spent many hours yesterday trying to fix this so that I could get back into my beloved Snow Leopard.

Just for anyone else who has this issue (from their own stupidity, just like me!) I did a bit of reading about Partition Identifiers.

Somehow, all three partitions of my hard drive had been changed to the NTFS id of 0x07 - The bootloader assumes these are NTFS volumes and will not boot them!

I used Partition Wizard to change the ID of my two OSX partitions to the HFS ID of 0xAF, and after a reboot everything was back to normal.

Best Regards
