Windows 10: Bitlocker fails with dual boot

I want the following final dual boot:1. Physical drive 1, no bitlocker, Windows 102. Physical drive 2, bitlocker, Windows 10My machine is an HP z840 with TPM 2, enabledAfter I install windows on the second drive, dual boot works perfectly. If I turn on bitlocker on the second OS, I am able to log into the first OS normally. However, the second OS asks for the bitlocker key, says it can't find the TPM, and does not accept the bitlocker key if entered.I have tried,1. Using the non-TPM option to save bitlocker key to a USB drive same behavior as above2. togglinging TPM enable in bios no change

Can I use Bitlocker with Dual-Boot setup?

BitLocker recovery keys after Dual Boot

Hi Varun Kelkar,



Welcome to Microsoft Community. I'm Mosken, let me help you.



According to your description, I knew that you were asked to enter the Bitlocker recovery key when dual booting Windows 11 with Windows + Linux. Is that right?

According to your description and the current situation, you may have used Bitlocker to encrypt the Windows system partition, but after you install the Linux system, the original system partition state has been changed, so you will be asked to enter the recovery key.



Generally, you will be prompted to save the recovery key when you encrypt with Bitlocker, as shown in the figure below.

• If you choose "Save to your Microsoft account", then it will exist in the Microsoft account you logged in when encrypting.
  

• If you choose the other three, it should be a .txt file with a long name contains alphanumerics, please recall whether and where you have saved it.
  

If you can't find the recovery key in your Microsoft account or the file that included the recovery key, I suggest you try unlocking the partition in Linux, back up your data, and then format the partition.

If it cannot be unlocked, sorry, there is currently no other effective solution to unlock a partition encrypted with Bitlocker, you can only reformat the partition to use it normally again.

The above steps are provided based on the information I have learned so far, and hope that could help you a little. If the problem still exists, please provide us a full PSR from the beginning, through the whole process, and until the error message is displayed, so we can further investigate.
