Full encryption of a multi-boot USB drive containing boot CDs and confidential information
I have been experimenting with XBoot (https://sites.google.com/site/shamurxboot/download) in order to create multi-boot USB flash drive that I can use for work (carrying around various OS and boot cds).
For those not acquainted with XBoot, it copies the various ISOs to the flash drive and creates a boot loader as a front end in either Syslinux or Grub4dos. Or can be set to not use any bootloader.
I would like to be able to carry around some bootable cds with company information preloaded onto them as well as having files stored on the drive.
For reasons pertaining to the information stored in some of what I'm carrying I would ideally like the entire drive to be encrypted.
The ISO files as well as the partition where data is stored.
Possible Solutions I've looked into:
I understand that TrueCrypt (http://www.truecrypt.org/) is capable of using its own bootloader in order to decrypt a drive before it boots. I've used this before and understand in theory how to encrypt a drive in which I'm booting multiple operating systems.
Edit: I know that TrueCrypt doesn't support EXT filesystems but the drive would be formatted as FAT32/NTFS with all of the boot cds existing as ISOs
Is there any way that I could install TrueCrypt to the drive and point one bootloader at another (It's not the cleanest approach but in my mind it stands the best chance of working)?
Is there a cleaner/more efficient way of achieving the desired result?
Ideally I'm looking for a software solution and not a hardware solution.
I managed to encrypt the entire drive using TrueCrypt but the front end bootloader isn't really meant to be used like a grub type menu loader. Does anyone have any experience editing the menu?
I tried using a different program as suggested by one of the responders, Easy2Boot. In functionality terms it works very similarly to XBoot in that it just creates a grub4dos boot menu front end for the ISO files. I ran into the same problem, where once this was set up, I couldn't properly point the truecrypt bootloader at this bootloader. So how would I accomplish this? I know it's possible because even from Easy2Boot, when I boot a live cd like Hirens it goes from the Grub4DOS bootloader to the Hiren's Bootloader.
