How do I dual boot two Windows 7 installations?
Hello. I'm looking for a security solution when it comes to stolen laptops. I would like a solution that involves both full system encryption for the main O/S, and a dummy O/S that is loaded with location tracking and spying software.
The problem with doing this on one O/S is that full system encryption requires a password at boot, meaning the thief will be forced to wipe the HDD and the location tracking software will never get a chance to work. Likewise, I can disable the encryption and use a guest account on a single O/S, but that leaves my files vulnerable. I could also use a Truecrypt container for my secure files, but they are of fixed size, cumbersome to use, and can't protect all sensitive data without mucking up the main user account.
The best solution would be (ideally) as follows:
- One Windows 7 installation fully encrypted using Truecrypt.
- One Windows 7 installation setup as a dummy O/S.
- Grub Bootloader that can load either O/S (Grub supports unlocking Truecrypt).
The two main problems that I have with this setup, is that this requires 5 partitions (2 for each Win7 install, 1 for grub), and I haven't figured out how to reduce this number. I can only have 4 primary partitions on a drive using MBR. Another problem I'm having, is that Windows 7 likes to mess around with the drive letter assignments, refuses to boot from anything but C: drive, and doesn't check UUIDs or anything else when selecting which partition to boot.
I can try to do this with Windows XP as the dummy O/S, reducing the partition number to 4, and Windows XP will boot off any drive letter. Still, Windows has a problem with attacking other Windows installations, and causing general mayhem. Windows does not like to share the HDD with other Windows, go figure.
It feels like a big step backwards that Windows 7 is less flexible than XP when booting multiple O/S, and I'm hoping that there is some trick to getting this to work. I have tried looking into UEFI as well, but getting Windows 7 to work on UEFI has proven equally impossible.
I'm hoping someone more knowledgeable than me can give me some advice, or maybe have some tips and ideas on how to approach this in a different way. I feel like there should be a way to make this work, but I'm out of options. Any help would be appreciated. Thank you!
