Backstory: After moving a Macrium Reflect disk image from my TrueCrypt external drive (with whole disk encryption) onto an unencrypted drive and using Windows PE with Macrium Reflect to restore my internal disk to the recovery image on the external unencrypted drive, my Windows 8 failed to boot. I then went back and also recovered the System Partition (looking now, it is currently EFI), but I still couldn't boot into my backup.
I was in a hurry to get online for something so I just did a clean install of Windows 8, without the backup. After I installed Windows 8, I went into Disk Management out of curiosity to see if there were other partitions with Windows 8 that Macrium might have missed, and there is (by default) a Recovery Partition of 100MB. My memory of this is hazy, as I was trying to get up and running for an exam at 4 AM.
Something in Disk Management prompted me to convert my encrypted external drive to GPT. I have no idea why I did this, but I went ahead and allowed it to convert my TrueCrypt drive to GPT. Now, I can't mount the drive in TrueCrypt. Disk Management sees it as Disk 1, Basic, and Unallocated. I tried converting it back to MBR with Disk Management, but no dice with TrueCrypt.
If I try to mount the disk in TrueCrypt I get the message:
Incorrect password or not a TrueCrypt volume
I should never have messed with a Truecrypt drive in Disk Management, but I did. I have important college work in that drive, and fear I have lost it forever.
How to recover?
