HELP! Enabled FileVault now won't boot.

[pmcdn]

MacBook Air with Mavericks. I enabled FileVault and only get grey screen with turning gear under logo. Won't boot.

How do I fix this?

At what point did this happen? When you turn on FV it reboots and starts the encryption... did that happen and did the encryption complete.

Try a command-r boot to recovery and see if the disk is visible from there in Disk Utility?

I enabled FV and when I (later) went to reboot, it wouldn't. I have tried booting from the recovery disk and when I select the disk (it is visible in Disk Utility) and click file/decrypt, it looks like it is starting but the progress window says there is an error.

Frustrated.

----------

While booted on an external drive, I go into DiskUtil and right click on the mac drive and select "unlock". It is now mounted.

What can I do now to decrypt it so I can boot from that drive?

In Disk Uitl look in the File menu and there is an UNencrypt option there.

I can see the contents of the drive in Finder as it's not mounted. So how come I cannot boot from it??

I have a similar issue but cannot get it to boot in any mode - verbose, recovery etc

holding down alt/option key seems to half work - I see a cursor that I cant move but no menu bar or anything to click on: I left it almost 45mins hoping something would appear
