Hi all,

I thought this would be a simple scenario to set up, but after doing quite some research, it doesn't seem so simple, as there are quite some unanswered questions on the subject in this forum.

Scenario: One disk, UEFI PC, two Windows installations, each in their own partition. It doesn't really matter if Win7/Win10, Win8/Win10 or whatever, so let's just assume Win10/Win10.

Having one of them encrypted and the other unencrypted is no problem. Having a Windows/Linux combination eather, as widely documented. But what about two Windows system partitions on the same drive, both encrypted?

So this is what I found out:

  • Encrypting the whole disk doesn't work and wouldn't make sense anyway in this environment
  • When encrypting both partitions, using the same password, only the last one that was encrypted would boot. If you try to boot the first one (through Windows bootloader that appears after VC password prompt), you will only get the recovery screen.

What's the trick to be able to boot both Windows installations?
