Bitlocker recovery key is asking after changing the mother board in dell laptop?

Recently, I have changed mother board in my dell laptop. But it is asking for bitlocker recovery key. I have never enabled bitlocker before changing the mother board, so, I don't have any backup for bitlocker recovery key.

How can bypass the bitlocker recovery key so that i can not loose the data. I have checked by Microsoft account but there is no any device displays. So I can't able to get back any bitlocker recovery key.

 

Upgrading to a new mother board

I purchased a prebuilt gaming PC.. I am going to be upgrading to a RTX 2080ti and adding more ram to it. eventually I am going to Dual 2080ti but my motherboard only supports 1 video card ASUS Prime B450. I am going to purchase a new mother board that supports
multiple GPU's. My question is.. will I have to purchase a whole new version of windows for the new mother board?
