Bitlocker locking me out of laptop computer

I tried to start-up my laptop yesterday and I got a blue "Bitlocker" screen come up and it is asking for a recovery key.  It notes the reason "..because Secure Boot policy has changed."

• I never installed Bitlocker, or set-up.  Frankly, I never heard of it.
• I checked my microsoft log in and there was no bitlocker recovery key in there either.
• I haven't made any changes to the computer recently.
• Computer is an HP Envy with solid state drive I believe

I am at a loss as to how to deal with this without loosing my data.  I spoke to three computer guys and they were not familiar with the Bitlocker.

Any assistance would be greatly appreciated.
