I am looking for multi-platform on-the-fly encryption tool, both truecrypt and luks /dmcrypt/ can provide, but I cant have dual boot /Linux&windows/ in this case, because TC does not support multi boot with other than Windows OS and luks is not supported on Windows or am I wrong?

I was thinking about this option: Have a initram which will mount luks device with encrypted Windows and than start another grub which will chain windows' boot loader is this possible?

Or have you got any better solution?

To be clear I would like to encrypt whole disk, not just part. Also no readable headers /information about encryption/ in plain text /as luks has/ seems to be like nice to have feature

FreeOTFE can use LUKS volumes; however, it doesn't support encrypting the boot partition yet. – grawity Oct 4 '11 at 13:55
Starting GRUB from within Linux will not work. First, the bootloader expects a fresh uninitialized system, but Linux has already initialized all hardware and switched the CPU to 'protected' mode. Second, dm-crypt is a Linux feature. The moment you start Windows, dm-crypt stops working. – grawity Oct 4 '11 at 13:57
@grawity Well I am OK with non-crypted /boot partition as long as it is just small place with no interesting data. – Ency Oct 5 '11 at 7:52
@grawity What about to have Windows partitions encrypted with Truecrypt and Linux with Luks and have USB Pen with Grub for linux or something like that? – Ency Oct 5 '11 at 11:03
