Comment 4 for bug 367322

I noticed the following in your DpkgTerminalLog.gz file. Have you removed grub?

No GRUB directory found. To create a template run 'mkdir /boot/grub' first. To install grub, install it manually or try the 'grub-install' command. ### Warning, grub-install is used to change your MBR. ###
