I’ve been attempting to install Linux alongside my BitLocker encrypted Windows 10. Fortunately, I was able to get Linux running alongside Windows in dual boot mode without any issues.

However, during the installation process, I had to disable UEFI secure boot to bypass the complicated process of making Linux bootloader work with UEFI. Prior to Linux installation, I disabled secure boot and Windows requested my BitLocker recovery key, which I successfully retrieved from my Microsoft account and entered.

After completing the Linux installation, I attempted to boot into Windows but encountered a message saying, “There are no more BitLocker recovery options on your PC. You’ll need to use recovery tools. Press the Windows key for UEFI Firmware Settings.” To resolve this issue, I searched for a solution online and created a rescue USB to disable BitLocker once and for all.

To my surprise, when I attempted to use manage-bde -unlock C: in the command line, I was prompted to retrieve my BitLocker recovery key from my Microsoft account, only to find that there were no BitLocker recovery keys uploaded. This was confusing, as I had just used two BitLocker keys before. It appears that BitLocker keys may not be reusable, but this was not communicated to me before.

Now, my entire C: drive is bitlocked, and while I have backed up my files, I don’t want to erase my whole drive and reinstall Windows 10, only to repeat the Linux installation. I am unsure of what to do next.
