hard drive - Bootable USB stick with Truecrypt

I want to boot the TrueCrypt rescue disk from a USB flash drive. I have Windows 7 64bit so I cannot use Grub4Dos to do this (it only works on 32bit system), and 99% of all documentations on how to create this rescue USB stick involve Grub4Dos.



So I tried using a program called FlashBoot but couldn't figure it out. I did some operation on the USB stick using FlashBoot, to make the USB bootable or something to a DVD ISO. However as I got lost and wasn't sure what I was doing, i abandoned FlashBoot and just formatted the USB stick.



Then I found the following instructions to USE syslinux for this purpose:

Ok, this is how it worked for me:




  1. Format the USB-Stick with FAT

  2. Download the newest SYSLINUX package.

  3. Extract the syslinux archive (in my case the newest one was syslinux-3.70.zip)

  4. The only 2 files you actually need from the archive are syslinux.exe from the win32 directory.... and memdisk from the memdisk directory.

  5. Assuming your USB-Stick has the drive letter X, execute the following command: syslinux X:

  6. After that there should be a (hidden) file on your USB-Stick called ldlinux.sys

  7. Download BBIE or (any other image extractor you know works).


  8. Assuming your USB-Stick das the drive letter X, execute the following command: bbie TruecryptRescueDisk.iso. Then this process should have created a file called image1.bin

  9. Rename image1.bin to something like tc.img

  10. Copy (the previously extracted file) memdisk and tc.img to your USB-Stick

  11. Create a file on the USB-Stick called syslinux.cfg with the following content: default memdisk initrd=tc.img




I followed those instructions to the letter. Before doing so I again formatted the USB stick, this time as FAT32 with 16k. Then I tried to restart the system. This is what I saw (large version):

Now why on Earth would it say FlashBoot loader there? It seems very bizarre. I formatted the USB stick, a full format that took like 5 minutes. Not only that but after seeing this I formatted it like 5 times and redid the above instructions and still see this screen.



Does anyone have an idea where I am going wrong here?



I'm asking this question here and not on the Truecrypt forums because they really frown upon people asking this question there, as it has been answered many times. They simply will not help. However my case has not been answered by the numerous tutorials on the internet.
