[Bug 484102] Re: Grub2 doesn't chainload truecrypt loader correctly

[Phillip Susi]

Grub can not be in the MBR if you are using truecrypt, since it requires
the embed area to function.  You must therefore, install grub to the
partition and truecrypt to the MBR.

You have to press escape to get to grub because truecrypt is in the MBR,
and you need to press escape to bypass truecrypt, and load grub in the
partition boot sector.  If your goal is to boot windows, then you should
not press escape to get to grub.

Title:
  Grub2 doesn't chainload truecrypt loader correctly

Status in “grub2” package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: grub2

  I am working on a dual-boot system with one hard disk.
  sda1 = /boot
  sda2 = Windows Vista Ultima encrypted with TrueCrypt System Encryption
  sda3 = Ubuntu 9.10 encrypted lvm

  The grub2 entry for windows is created by the file 50_windows in the
  "/etc/grub.d" directory:

  #! /bin/sh -e
  echo "Adding Windows Vista entry" >&2
   cat << EOF
  menuentry "Windows Vista" {
  	set root=(hd0,2)
  	parttool (hd0,2) boot+
  	chainloader (hd0,1)/truecrypt.mbr
  }
  EOF

  Choosing this entry in the grub2 menu the Truecrypt loader only shows the following message: 
  "TrueCrypt Boot Loader
  Load damaged! Use Rescue Disk: Repair > Options > Restore Truecrypt Boot Loader"
  But this would install the Bootloader into the MBR, where grub2 shall be. The TrueCrypt Loader is in /boot/truecrypt.mbr
  Booting Ubuntu works without problems.

  With grub-legacy the chainloading worked.

  The menu.lst:
  title		Windows Vista
  rootnoverify	(hd0,1)
  savedefault
  makeactive
  chainloader	(hd0,0)/truecrypt.mbr

  My Grub2 version: 1.97~beta4
