I headhunt IT specialists for areas of Financial Services and currently have career opportunities with Top Tier Investment Banks, Hedge Funds and Consultancies. I have a number of great job opportunities coming up that I would like to discuss with you. Can you give me a call or email when you have a moment, whether you are actively or passively looking? Alternatively, if you have an updated CV you can pass over, we can then discuss specific and relevant roles I have in more detail.

]]> Comment on Encrypting both OS X and Boot Camp by Steve http://www.lukefitzgerald.co.uk/2011/09/encrypting-both-os-x-and-boot-camp/#comment-163 Steve Fri, 20 Jan 2012 16:13:23 +0000 http://www.inflatablegoldfish.com/?p=103#comment-163 Thanks for posting this solution. I considered Jason Gouger's option, but was concerned about the amount of work involved for several boxes and its overall robustness, especially given my limited experience tinkering with MBRs and grub. I went instead with PGP Desktop version 10.2 MP2 and can confirm that this works very well for Lion 10.7.2 with Bootcamp and Windows 7 x64. The setup is simple for an existing Bootcamp setup: (0) Backup everything using Time Machine and/or Carbon Copy Cloner for OSX and WinClone 2.3.3 for Windows 7 (after doing a "chkdsk /f /r" plus reboot); (1) Install PGP Desktop on the Windows 7 partition; (2) Install PGP Desktop on the OSX partition, reboot into OSX, and encrypt within OSX. This has the chief advantage of whole disk encryption: being able to see (and backup) the entire drive from each OS -- it works just like an unencrypted Bootcamp setup. Also, holding down Command-R while booting into the OSX partition still works to boot into the Lion Recovery Partition. ASFAIK, this is the *only* existing automated encryption method for dual boot boxes without the necessity of mucking with grub bootloaders. In the future, it would be nice-to-have if File Vault 2 were capable of whole disk encryption, if Truecrypt allowed encryption of arbitrary partitions or WDE, or if WinMagic supported Bootcamp. But right now, PGP Desktop appears to be the only workable solution. The nice thing is that it works and works well. Thanks for posting this solution.

The biggest issue to work around was the fact TrueCrypt (TC) boot loader exceeds the maximum size that can fit in the first sector, it extends into the GPT rescue partition and corrupts the GPT partition table data. Since it is not possible to install the TC bootloader I used GRUB/GRUB4DOS to load the ISO recovery image of TC to boot the proper windows partition. I managed to setup the partitioning to allow Windows to install on the "second" MBR partition. My GPT partition layout is : 1. GPT Rescue 2. GRUB Boot 3. Windows 4. OSX I used gpart from the Linux SysRescue CD. I created the layout above, and created a Hybrid MBR with partitions 2 and 3. I installed OSX Lion onto the OSX partition. Once this was setup I proceeded to install Windows. You can only format the windows partition during the installation, do not do any partitioning as this will corrupt the GPT data. With windows installed and working installed the BootCamp drivers and then installed TC. Installing TC will corrupt your GPT/Hybrid MBR setup as it will overwrite the GPT table and GPT rescue partition when it writes the bootloader. Now you will need to use the Linux SysRescue CD and gpart to restore the GPT partition table from the backup and recreate the Hybrid MBR. With the partition table rebuilt you will need to setup GRUB/GRUB4DOS to load the TC recovery ISO to boot the Windows partition. This involves installing GRUB and then installing GRUB4DOS as the boot image for GRUB. GRUB4DOS can then be setup to boot the TC recovery ISO. Once Windows/TC was all setup, I went back to OSX and enabled FileVault. If you did everything correctly you will notice that the disk partition tool under OSX still reports the disk as a GPT disk, not MBR. If it is reported as MBR FileVault will fail to enable. Booting the recovery ISO is a bit messy, but it does accomplish the task of using both FileVault and TC. Perhaps TC will be improved in the future such that it creates a multistage boot loader and using an additional partition instead of just overwriting beyond sector 1 which just happens to work for Windows.

I've certainly not seen any new methods pop up. I think going with the additional encrypted partition after Windows is probably the best option. With regards to how secure it is; if your computer has a keylogger on it, your work is probably already compromised and you should have anti-virus software to detect that sort of thing.

I'm curious, did you come up with a solution to this yet? Luke, Great post- I have the same problem. I’m curious, did you come up with a solution to this yet?
