Lost bootcamp after using mini tool partition to increase windows partition size

Seems to be a very common problem that requires a lot of customisation so many thanks for the support in here people 🙂

There are so many threads to go through but figured to mention my problem maybe it has been solved before and i can follow the footsteps.

What i did was reduce OS X partition size, restart in bootcamp windows 7 and used Mini Tool Partition to acquire the free space. Restarted windows worked great for a couple of days until i restarted in OS X which as most threads here have boot camp is called disk04 and can not be mounted nor can it been seen in startup disk.


All i want is to get the windows working as i have no backup (i know!) and to sort out the missing space.

I will continue to go through the post but any pointers will be appreciated !


As per original post, here is the results:

1. Please backup OSX and Windows to separate physical external disks, if possible.

2. Gdisk has a 'b' command, which creates a backup of your GPT and MBR. I suggest a backup and storing externally on a USB or some other media, if there are any future issues.

3. Post a link to the referenced discussion and I will put a clear warning on that thread.
