File Share Encryption

Hi there,

I dual-boot Windows 7 & Ubuntu on my laptop. Grub2 is installed on /dev/sda and holds the usual entries for ubuntu & windows. /boot does not have a separate mount point but is part of the / filesystem.

After using PGP WDE, I can't boot into Linux. The bootloader displays correctly, however after selecting ubuntu, I get the following error:

ALERT! /dev/disk/by-uuid/fd6a6515-36af-42c5-bd3d-a8ab944ea200 does not exist. Dropping to a shell!

Selecting Windows from the bootloader boots normally.

If I boot into windows and unencrypt my disk, I can then boot into ubuntu with no problem.

Any thoughts at all?

Thanks,

JD.

Thanks Tom, however I'm not actually trying to install PGP WDE in Ubuntu, merely encrypt the whole drive from within windows so I can boot into either.

Is simply that I just need to encrypt the C: partition from within Windows rather than the whole disk?

Please see the partition encryption section of this KBA:

Sorry Tom, I've been travelling the last couple of days.

Yes - it was useful, thanks!

I think I was assuming that accessing a WDE'd DISK was simply a matter of providing a valid key on boot, regardless of the OS booted into. However I'd not thought it through and realise now that that could never work - Ubuntu on the other partition would need to be able to access it's root partition through a decryption process.

So, simply encrypting just the Windows OS partition solved that.

Thanks very much for your posts. I'll mark as a solution.

James.
