Computer locked: Prompt for BitLocker recovery key on blue screen - without previous BitLocker configuration for disk encryption
The problem as above - the notebook functioning correctly and out of the blue while starting it requests the Bitlocker RecoveryKey.
Never
before has the bitlocker been configured (consciously by the user) on this hardware to encrypt the disk, the bitlocker has been run once, a few months earlier, solely to read data from the encrypted external disk.
Trying to use that password - unfortunately, it does not give positive results.
There are no saved keys on MS accounts (which were not intentionally
transmitted), nor printed or saved – as it has not been set by user. The computer has never worked in AD, so it’s
not the case that the settings are given administratively "by the organization".
Checking
the status of the bitlocker from the console indicates that the disk is encrypted and the password is in TPM, but for unknown reason, at the start of the computer bilocker does not read it from there.
There
was no attempt to interfere with hardware, BIOS, etc. Searching
the web shows that the problem has recently appeared not only i: https://www.dell.com/community/Windows-10/BitLocker-need-a-key-but-I-never-installed-it

Unfortunately, the solutions provided in this forum - did not bring a solution.
Although this is a Dell forum - it can be seen that it is not dependent on the hardware, the XPS13 user writes there, my notebook
is Asus. BTW the hardware manufacturer
claims that it has no affect on this problem, disk encryption has not been configured by the manufacturer (the system was not installed and configured on the computer).
Any
ideas what it can be and how to get around it?
Error after upgrade?
How is it possible that the disk is encrypted without the user's knowledge?
And why the password stored in the TPM (where
did it come from?) Was no longer available for the bitlocker?
