Sometimes when you start machine with BitLocker enabled and same time some storage device was connected to USB port, BitLocker might request Recovery Key. This happens because USB ports is listed on boot device search list. To avoid this type of event best idea is to remove USB from boot search list. However, changing list of boot devices might also trigger BitLocker.
How to deal with this type of situation? Follow steps below:
- Suspend BitLocker – command: manage-bde -protectors -disable c:
- Reboot machine
- Go to BIOS and remove all USB devices from available boot devices list
- Boot up to Windows
- Resume BitLocker – command: manage-bde -protectors -enable c:
NOTE: All above commands have to be issues from Command Prompt with elevated privileges.
After that no more issues with BitLocker during startup when USB storage devices are connected.
