Hi,

i have a 500GB HDD, with

Partition 1 = 100GB (Windows 7 installed)
Partition 2 = 300GB (Windows 7 installed)

First i installed on Partition 2, then on Partition 1. Without Diskcryptor installed
i can choose which Window partition to boot in the boot screen

Windows 7 (C:)
Windows 7 (D:)

So...until here everything's fine.

After installing Diskcryptor on C: and D: i encrypted C: with password 12345
and D: with password 67890 and set boot option to "boot from first partition
with appropriate password". -> reboot

I expected:

if i enter 12345 -> boot C:
enter 67890 -> boot D:

In the end, it only proceeds with the password 12345, then i can choose
which Windows to boot over the Windows bootmanager as seen above.
C: works as expected, D: fails because no os found (which makes sense
cause the system is still encrypted)

If i enter the correct password for D: = 67890, it says "No Operating System".

Am I missing sth?

Thanks in advance

Hello,

I'm not sure why that happens, but I think I know how to get around that problem.  If you dual boot 2 copies of Windows 7, I suggest that you set up each copy of Windows 7 so that its boot manager is on the same partition as the system being booted.

That way, you enter a Diskcryptor password at boot, and Diskcryptor mounts a single partition to get everything going.  The copy that starts depends on which Diskcryptor password is entered.  A different copy of the Windows boot manager would get decrypted for each password, and the Windows boot manager would not ask what system to load.

Thanks for your answer.

Ok, so though i've installed first D: and then C: the installer puts
the bootmanager (boot stuff) only under C: ?

So, how can i change this. (Clean install is no problem, as there is
nothing on the disk, except the test Windows)

How can i verify if the boot options are correctly set...are there any
Windows tools onboard?

The correct boot option in Diskcryptor is still "boot from first partition
with appropriate password"?

Thanks

Ok, i got it to work.

Problem was indeed the bootloader, which has been installed only
on C:. To change this, i did the following.

- boot from Windows 7 CD

- partitioned the disk with the GUI so you have
    100GB for C: (System)
    300GB for D: (Primary)
    I don't use the Windows 7 specific 100MB partition

- now the important step. Because only C: is marked as active/System
partition, all boot stuff is installed here...so we have to change that.
Inside the GUI press "Shift+F10" (cmd window) and type:

diskpart
list disk
select disk 0 (in my case 0)
list partition
select partition 2 (cause i want D: to be active/System)
active (set active/System)

Close the window and back in the GUI press 'Refresh'. You should
see the following: (System is now D:)
100GB C: (Primary)
300GB D: (System)

Then do the normal install on D:

Now to install Windows 7 on C: do the same again, in reverse order,
that means -> mark C: active/Sytem and proceed with the installation.

The biggest difference if you boot for the first time...there's no boot
manager and you cannot choose which Windows to boot.

To install Diskcryptor:
- install on C: and reboot
- open command window, mark D: as active (otherwise you won't get
into D: again to install Diskcryptor)
- boot into D:, install Diskcryptor, reboot
- open command window, mark C: as active, reboot into C:
- back on C: start Diskcryptor-> encrypt C: D: with differerent passwords
- set boot option "boot from first partition with appropriate password"

That's it.
