windows decided not to boot
Same issue with my laptop DELL lattitude...
You don't say anything about the current state of the drive? In what way is it worse? Does the partition boot sector look correct?
Also which option did you use to do the remove, and what was the original error?
The standard remove option works fine for pretty much everyone, the most common way of getting in the position you are in is by using the wrong sdb file, and you can tell that by checking the part boot sector is decrypted properly prior to running the decrypt.
But, knowing exactly what the original problem was helps - if the preboot was working but not windows, then the standard remove without using the sdb should be used.
