Getting Windows 7 (or Windows 8 or Windows Vista) with TrueCrypt to play nicely with GRUB2 is quite a chore. Although, after 2 days of fighting, I finally found a simple solution, thanks to the README file that comes with grub2tc. Unfortunately, grub2tc didn’t actually work for me, but their docs did!
Here’s the step-by-step to make it all work:
- Install Windows. In my case, this meant running the restore CD that came with my computer.
-
Install TrueCrypt, and encrypt your system drive. Be sure to encrypt only the System drive not the entire disk!
Be sure to copy the TrueCrypt Rescue CD image somewhere handy. I used a USB stick, but you could burn it to an actual CD just as well. But you will need this later for this procedure.
- Install Linux. I choose Debian, but these instructions ought to work fine with Ubuntu, or practically any other variation of Linux. If you’re doing disk encryption (and I’m sure you are if you’re reading this), be sure to create a small (~500mb should be fine) /boot partition that is not encrypted. Then configure the rest of your disk with encryption, LVM, whatever. When I had finished this step, my disk layout looked like this (from the Linux standpoint):
- /dev/sda1 – Windows 7 Boot partition
- /dev/sda2 – Windows 7
- /dev/sda3 – Linux /boot
- /dev/sda4 – Encrypted Linux volume, mapped to /dev/dm-0
- /dev/dm-0 – LVM Physical volume
- /dev/mapper/vg0-root – Linux / partition
- /dev/mapper/vg0-swap – Linux swap space
Note that it is important that your swap space is encrypted. Otherwise an attacker may be able to read passwords or other private info from the swap partition–especially if they gain access to your system while it is hybernated (suspended to disk).
When you install Linux, be sure to install GRUB2, and install it to the MBR. Many tutorials for getting GRUB2 to work with TrueCrypt say not to do this, and instead to install to your boot partition (/dev/sda3 in this case). I had absolutely no luck with these tutorials. If one of them works for you, great. But then you wouldn’t be reading this. So, go ahead and install to the MBR for now. This wll overwrite the TrueCrypt boot loader, but we’ll remedy that shortly.

Configure GRUB2 to boot TrueCrypt. This is the magic you came for. The procedure, which I borrowed pretty much exactly from the grub2tc README is to:
- Install syslinux
For Debian/Ubuntu:aptitude install syslinux - Copy ‘memdisk’ file into place for use by GRUB2
Again, for Debian/Ubuntu. For other distributions, the installed location of the ‘memdisk’ file may be different. (Hint: use ‘find’ or ‘locate’ to find it):cp /usr/lib/syslinux/memdisk /boot/ - Copy TrueCrypt rescue ISO into place
If you saved the TrueCrypt Rescue ISO to a USB stick, you just need to copy the file (called TrueCrypt Rescue Disk.iso by default) to /boot/truecrypt-rescue-disk.iso. For example (as root):mount /dev/sdb1 /mnt
cp /mnt/TrueCrypt\ Rescue\ Disk.iso /boot/truecrypt-rescue-disk.isoOr if you burned the image straight to a CD, you can accomplish the same thing with dd (again as root, with the CD in the drive):
dd if=/dev/cdrom of=/boot/truecrypt-rescue-disk.iso - Determine the UUID of your boot partition
You can read this from /etc/fstab, or with the following command (substitute the proper device name for your boot partition):blkid /dev/sda3The output should look something like this:
/dev/sda3: UUID="12345678-1234-1234-1234567890"Use that UUID in the next step.
- Configure GRUB2 to load TrueCrypt using Syslinux
For Debian/Ubuntu, the easiest way is to edit the /etc/grub.d/40_custom file. The exact file you edit may vary for other distributions. Add this to the end:menuentry "TrueCrypt ISO boot" {
insmod part_msdos
insmod fat
insmod ext2
insmod search_fs_uuid
search --fs-uuid --no-floppy --set=boot [UUID without quotes]
linux16 ($boot)/memdisk iso raw
initrd16 ($boot)/truecrypt-rescue-disk.iso
} - Tell GRUB2 to use the new configuration
Without this step, the configuration that GRUB2 actually reads is never updated, so your changes won’t take effect. On Debian/Ubuntu, simply run the following command:update-grubIt will give a short summary of output. If there are no errors, you should be set to go!
- Install syslinux
- Test it
Reboot the system. Your GRUB2 menu should now have a new “TrueCrypt ISO boot” option. If you select this option, you will see the TrueCrypt Rescue CD prompt, asking for a password. Enter the password and hit ENTER, and you should be booted into your Windows environment.
The only drawback I’m aware of for this boot method is that you see the TrueCrypt Rescue menu every time you boot into Windows. It might be slightly nicer to see the standard TrueCrypt menu (the one that doesn’t show the option to press [F8] for rescue options). But that doesn’t really bother me in the least. Plus, it might come in handy some day if I need to decrypt my Windows partition, and don’t have my rescue disk handy.
If you come across any problems with this procedure, please feel free to contact me. I can’t promise to help, but I am more than happy to update my documentation to help future visitors.

Chik-Fil-A president Dan Cathy recently made the news when he came out as opposed to same-sex marriage. This has all kinds of people upset. Gay-rights activists are calling for protests and boycotts against Chik-Fil-A, for being hateful. Many Christian groups are calling to openly support Chik-Fil-A and their freedom of speech.
At this time, fluoride was considered the worst industrial pollutant in history, and had lead to many lawsuits against industry.
Although the evidence that fluoride helped teeth was not particularly strong, a concerted effort was made to make it look as though it did by many of the parties involved. An early study, published in the 1948 issue of the Journal of the American Dental Association, which was “based on work performed … for the Manhattan Project” reported that Manhattan Project workers exposed to fluoride had fewer cavities than workers unexposed to fluoride. Later, a secret, uncensored version of the report was found, which reveald that most of the men in the study had few or no teeth!
Using a non-zoom lens also forces you to think about angles in a new way. You may see a beautiful tall building, and with a zoom lens, zoom all the way out so the building easily fits in your field of view. With a fixed lens, you may be forced to walk right up next to the building, and take a photo looking up to the top from an angle. You’ll end up with more creative shots that way. Consider the two photographs of the Empire State Building on the right to see an example of how limitations of a zoom lens (and the lack of budget to rent a helicopter) can add to the creativity of a photograph.
To research, I spent a couple hours on Google, looking for evidence for and against the practice of community water fluoridation. The key piece of evidence I found was a report by the World Health Organization (WHO) entitled 
But what is the truth? If CWF is as dangerous as the opponents claim, where is their evidence? And what is to be made about all the pro-fluoride evidence? If CWF is safe, as the proponents claim, then where are the opponents getting their information? Who has a motive to promote fluoridation if it’s unhealthy? Who has a motive to vilify fluoride if it is healthy?
