    Hello,
    I'm having a problem very similar to this guy: http://forums.techguy.org/hardware/903126-solved-hard-drive-partition-has.html

    The difference is, both of my partitions contain a Windows installation (both Win7). I switched on my PC one day to discover the D: partition had become an OEM partition and was set to hidden.
    I used DiskPart to change the ID of the partition to 07 and it works, the partition suddenly shows up.

    However, if I restart the computer, it reverts back to exactly how it was, every single time!

    How is this happening?

    Change the drive assignment to something other then D:

    It is likely fighting with a thumb drive or optical drive for that assignment.

    I recommend Something H: or higher.

    Thanks, I tried that, but it still didnt stop it disappearing.

    I eventually solved it by rebuilding the entire partition table and MBR (Using the BootRec.exe tool command line). The drive showed back up and the second OS works again.
    Thanks
