Hi,

I am just experimenting to figure out what is possible with the Vera Crypt Rescue disc, and have come across the following behaviour. I wonder if it's a bug, or if it's supposed to react like that:

System with Win7, MBR, all very normal.
System-partition (not drive!) is encrypted, works fine. (The drive contains just that one partition, all space is used by it.)

Experiment with Rescue Disc from a different Win7-System:

  • booting RD, entering PW: works, boots like normal
  • restoring Vera Crypt Bootloader to HDD: works, boots like normal
  • booting RD, restoring original system loader: of course, does not boot.
  • booting RD, restoring Vera Crypt Bootloader to HDD, reboot: "wrong password"

Then using the RD created from this system:

  • restoring Vera Crypt Bootloader to HDD, reboot: "wrong password"
  • restoring key files, reboot: now it works again.
  • again restoring original system loader, then restoring Vera Crypt Bootloader: "wrong password".

I would have expected that restoring original system loader, and then restoring VeraCrypt Bootloader, results in a working system, as both are only stored in MBR?
But instead, restoring system loader seems to overwrite also keyfiles? Is that correct? So the keyfiles are also stored in MBR?
