ok so it seems to work without this line in grub.cfg. I believe that I have played around with that a little because I found similar bug reports related to LVM..
I have done an update-grub , lvm line is removed, still booting. So the only thing I really need is the part of the cryptroot scripts. As the time I tried to fix that problem I needed to do that in order to get the password prompt for the encrypted disk: cp /usr/share/initramfs-tools/hooks/cryptroot /etc/initramfs-tools/hooks/ cp /usr/share/initramfs-tools/scripts/local-top/cryptroot /etc/initramfs-tools/scripts/local-top/ I also had added those both lines to /etc/initramfs-tools/modules lvm dm_crypt But I'm not sure if they are needed?! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1000927 Title: 12.04 new install or update: if LVM + full encrypted disk grub installation fails!
