Notes about Microsoft BitLocker/TPM
InstantRecovery supports Microsoft BitLocker/TPM by moving the pre-boot
operations to the same place that check disk runs. That is after the BitLocker/TPM
has unlocked the disk but before the operating system starts.
There are some necessary restrictions:
- You must setup BitLocker and encrypt your disk before installing
InstantRecovery.
- Before decrypting your disk you must completely uninstall InstantRecovery.
You can reinstall InstantRecovery afterward.
- All snapshots should be clones of the original encrypted volume.
This is because the encryption is specific to the original volume.
Any snapshot that is not a clone of the original encrypted volume
will fail to boot.
- Create Empty Snapshot is disabled if the volume is encrypted with
BitLocker/TPM. The purpose of this feature was to allow a separate
OS to be installed in the empty snapshot. However, this cannot be
done on an encrypted volume. An empty snapshot can still be created
with the CLI.
