Boot Camp drive showing up as Fat, can't mount

Right, I get where you're coming from, but all I really meant was that instead of deleting the FAT32(BOOTCAMP) partition I formatted, and also mentioned the BootCamp Utility to avoid confusion, since I'm sure there's a good number of people that wouldn't know how to do the same thing with Disk Utility.

No worries. Thanks for sharing you experience with this surprisingly common issue.
It's just that anyone who doesn't already know what they are doing will not end up where you did by following your original directions. This tends to add confusion rather than avoid it.
In these cases IMHO it is better to omit details rather than make them up, you can always add detail.

hi all,
i just want to share my problem and how to solve, although this thread was almost 6 months ago.
i have the same exact problem, but i experienced this error after i run Virtual Box and put the dynamic hard drive in my windows partition.
and then i remove the dynamic hard drive in my windows partition and decided to logon using vista.
during booting, i switch using windows partition, and it went restarted on and on.
so i try to find how and try to execute the command that appears in the dialog window.
i just execute the command :
mount -t ntfs -o force /dev/disk0s3 /Volumes
because when i use mount -t ntfs -o force /dev/disk0s3 /Volumes/Untitled,
it show some error.
so here is the result :
Tandhy-MacBook:/ root# mount -t ntfs -o force /dev/disk0s3 /Volumes
kextload: /System/Library/Extensions/ntfs.kext loaded successfully
Tandhy-MacBook:/ root# 63:92: execution error: SystemUIServer got an error: AppleEvent timed out. (-1712)
i can see the volumes mounted in Finder and i can access the file beneath it.
now i want to try log using vista inside it.

This doesn't seem like a good choice. If the system wants to create another mount point for another volume in /Volumes it won't be able to.
If you are mounting it manually, the mount point needs to exist, so you could keep it out of /Volumes altogether and use something like
Code:
mkdir ~/MountPoint
mount -t ntfs -o force /dev/disk0s3 ~/MountPointB
Help!
I had the same problem like on TOGGI3's, but I can't understand the instruction on his resolution. I'm a newbie on MacOS, can anyone instruct me easily? I'm dying to know how! 😕

So, yeah... I have this problem too
I have installed gdisk and I have run the following through the terminal:
Code:
gdisk -l /dev/disk0this is what I got:
Code:

old thread but here is what needs to be done:
1.use partition inspector that comes with refit to get info on the GPT and MBR tables (they are probably out of sync)
2.use gdisk to manually change the GPT table to match the MBR table.
To use gdisk on main disk do sudo gdisk /dev/disk0. Type ? for list of commands.
So a pair of tables:

Now my turn to apologise for bumping the thread.
Recently tried to update my Mac 1.1 to take Mountain Lion - no dice, after trying Jabberwok's walkthrough. The Mac decided not to boot a thing, so I took out the SSD that had his tools on it and went back to Mac OSX Lion.
After a few attempts, my Windows XP (I know!) Bootcamp partition won't boot from the Startup disk, or from holding down Option at bootup. Nor will the Mac boot from a USB stick either.
I've got the GUID and MBR partition tables from gdisk and fdisk respectively - they are as follows:
GUID:
1 - 40 - 409639 EFI
2 - 409640 - 1758222119 Mac 1Tb
3 - 1758484480 - 1953523711 BOOTCAMP
MBR:
1 - 1 - 409639 (Unknown ID)
2 - 40640 - 1757812480 HFS+
3 - 1758484480 - 195039232 Win95 FAT32L
4 - 0 - 0 Unused
I know line 3 on the MBR looks wrong - but that's what it is.
Need help and advice if only to be able to mount the disk and remove some very large 3DS Max files from it.
Sorry - more information to add. BOOTCAMP was set up on my HDD in bay 2, my Mac OS in in bay 1. Until this issue I had no problems whatsoever with this arrangement.

To be safe, just download some backup utility such as Winclone to create a backup of your Windows partition. Then recreate your BootCamp. When you're in the step in selecting partition where Windows will be installed, select the BootCamp partition, format it (not delete), then install.
