I have a company laptop with a sophos encrypted drive that boots to a Workstation Is Locked screen. I tried doing a recovery with chall/response but in my Sophos Enterprise Console I get a msg that there is No Backup Key Available For This Computer.
I've also booted to winpe with a usb drive containing the recovery token. I submit the chall/response and get the same msg about no backup key is available.
What other options do I have?
Any help will be greatly appreciated, thanks!
