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

[Janosch Maier]

Public bug reported:

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
