I had the same issue and I was able to solve it by partitioning it manually and putting /boot as first partition. I could not use the 'search' deletion trick because with lvm+encryption it doesn't even reach the grub menu (but I had the same error message as in this bug report when installing without lvm or encryption).
Note that on my old 80GB disk everything was fine. Problems only arose when I tried installing on a new 320GB disk. -- Grub 2 problem, error: no such device https://bugs.launchpad.net/bugs/403408 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
