I have followed this thread as it descirbes my problems after installing Mavericks. Do the steps described by Christopher Murphy to add the bootcamp partition back to the MBR work if my primary OSX partition is encrypted using file vault?
The example posted by tomd007 on page 50 suggests that I have to add the primary OSX partition to the hybrid MBR in the process of restoring the bootcamp access. Since the OSX partition is encrypted, do I need to point to a specific unencrypted partition that will initialize the decryption process for the primary OSX partition?
Thanks in advance for any help.
My bad. I never tried to resize the partitions, just want to restore the access to my bootcamp partition after Mavericks messed up the MBR.
Anyway, here are the results for

I appreciate your help.
You can fix this either with gdisk (gpt fdisk from sourceforge) or the already present fdisk on OS X. Using gdisk you'll create a new hybrid MBR using the already mentioned method, add partitions 2 3 4 and make 4 bootable.
If you use fdisk to edit the existing MBR rather than make a new one, you'll use setpid command to change partition 4's type code from 0C to 07. And use the flag command to make it bootable.
sudo fdisk -e /dev/rdisk0

Hi guys, I have now this problem.
I did both created a third partition (accidentally) and updated to Mavericks. Now the Windows partition is not showing anymore when restarting and using the 'alt' button, it does in disk utility though and I really need to make it work because I have really important data and software there I use for working so please give me a hand.
The thing is, I don't have that much experience in mac computers and I am finding pretty tough the explanations given here (and there are already 57 pages...) , so anyone who can help me step by step? or maybe already someone did this job and can write me the link? I really appreciate.
Thanks and really looking forward to hearing from any of you
1832 sectors free space is less than 1MB so you don't have the same problem as the most recent posts. All you need to do is fix the MBR #4 entry, whose id is set to 0C instead of 07. You can do this with fdisk, which comes with OS X. The commands you need are setpid, which will let you change the 0C to an 07, and the flag command will let you set the boot flag on that #4 partition. And the write command will write the changes, as will the quit command. The abort command, or simply a control-c will cause no changes to take effect.
