Hey everybody,
I'm following this guide to reinstall Ubuntu on my computer because of a seemingly untraceable software bug concerning my CPU, but testing it in a VM first:
http://kuparinen.org/martti/comp/ubuntu/en/cryptolvm.html
The basic gist of it is to create an encrypted dm-crypt/LUKS partition and then a LVM setup.
I'm using an Ubuntu 10.10 Alternate CD disk in Advanced Mode.
I have no problems with the guide, but at the installation step of installing GRUB2, it fails, without giving me a remotely helpful error message. It tells me installation on '/dev/sda' (MBR install) failed at 50% and thats pretty much it.
So I'm I missing something? Should I be installing GRUB2 somewhere else? Like on the LVM volume/logical group?
Here's my HDD setup:
(20 GB VirtualBox HDD)
-1 Encrypted partition with dm-crypt
--1 LVM Volume Group
---3 LVM Logical Groups (/,home,swap)
__
By the way, there is no separate /boot partition, to my understanding GRUB2 can handle encrypted LVM's without a separate /boot partition without issue? Is this my problem?
After trial/error and combined searching for a solution for 8 hours I'm at a loss. I've looked at these pages and much much more:

I've also used live-cd's to chroot into the encrypted LVM environment and install grub and trying other things but nothing works. And most documentation is outdated. I haven't tried any other boot loaders like SysLinux or LILO, I would like to get GRUB2 to work.
Thanks, any suggestions are welcome.
