about to install linux on the x13s and found that I need to disable secure boot and there are messages at the bios telling me to backup the bitlocker encryption key. I'm not familiar with windows or bitlocker. After google-searching, I found this command `manage-bde -protectors C: get` which shows the following
```
BitLocker Drive Encryption: Configuration Tool version 10.0.22621
Copyright (C) 2013 Microsoft Corporation. All rights reserved.

Volume C: [Windows]
All Key Protectors

ERROR: No key protectors found.
```
I don't personally care about this, but if I need to give or sell the machine to someone else they might need to install windows there. what should I do?
