Windows 10: Firmware bios update triggered bitlocker encryption

Good afternoon, my DELL XPS 13 did an automatic firmware BIOS update and now is prompting me for a bitlocker key which I never set up. My device shows up in my Microsoft account when I check on my phone but there is no associated bitlocker key when I click manage keys. Nor on any of my other Microsoft accounts.

Can't get Bitlocker to encrypt C: drive

Thanks for your reply. I have not looked at the BIOS settings. Have not changed the BIOS since I originally encrypted the drive a couple of years ago, and it worked fine then, but it's worth a look.

I'll take a look at the settings when I'm in my office again and report back.

OK. Looked at BIOS, enabled Secure Boot and UEFI, computer would not boot. Went back to Legacy Boot and UEFI disabled. Booted.

Went though Bitlocker setup again, this time at final stage, unchecked "Run Bitlocker system check," and encryption started. Tomorrow I'll see if I have created other problems. If so, probably next step is to wipe the hard disk and start over.

Final post: What I did above worked. Drive is encrypted. When I restarted, I got the expected blue screen asking for my password. So all is well . . . at least so it seems.

Thanks to those who offered suggestions. I appreciate your input so much!
