I have a disk with three partitions:

  • Windows 8.1
  • Data
  • Windows 10
    The Windows 8.1 system partition was already encrypted with VeraCrypt, so I need to type the password at boot to start windows.

I now want to encrypt the Windows 10 system partition. I selected the "multi-boot" option in VeraCrypt, however, I'm getting a warning:

"CAUTION: The VeraCrypt Boot Loader is already installed on your system drive...proceeding with encryption of the currently running system may make other system(s) impossible to start..."

Is it really true that VeraCrypt doesn't recognize that other system partitions have been encrypted and installed as boot options? Is the warning correct? Will my existing Windows 8.1 encrypted system partition become inaccessible?

I don't want to encrypt the entire disk because the data partition is huge and there's no need for it. is it really not possible to have multiple encrypted system partitions set up to multi-boot?
