Update: If you're having a similar problem, try leaving it on on the grey boot screen overnight (ie several hours). In my case that seemed to resolve the issue. What the issue was remains a mystery.
As I , and others have discovered, the latest ML update completely messes up your hard drive layout to the point that Bootcamp/Windows will not start.
To give you an idea how much it screws things up here is my disk layout *after* the update:
gpt show: disk0: mediasize=751277983744; sectorsize=512; blocks=1467339812
gpt show: disk0: Suspicious MBR at sector 0
gpt show: disk0: Pri GPT at sector 1
gpt show: disk0: Sec GPT at sector 1467339811

</sigh>
Short of completely wiping the disks and starting from scratch (but how without ML disks?!?) I have no idea how I am going to fix Apple's monumental **** up.
Don't they test their damn patches? This one was specifically for the rMBP so it's not as if they have a lot of variations test?
