This bug effects me as well. In my case the machine, Dell XPS 9100, installed and ran UEC 10.10 front end. Upon installing 11.04 the install goes fine and, upon reboot, I get a fast blinking cursor with a black background. I am using LVM but with NO encryption.
As a tangential, I have the same problem with U 10.10 installed on a Dell PowerEdge T410. I thought it had to do with the new graphics card but, seeing this problem on a machine that did run 10.10, I suspect it is this grub bug. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/745960 Title: Cannot boot grub after installing to LVM -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
