Re: Grub2 install with / on lvm

[jeff]

The quick work around you suggested did not work.  The result of that was when 
booting it would display several lines of an error message "failure reading 
sector x?x?x?x from hd1".  These several lines would alternately display and 
disappear, seemingly as if it was stuck in a boot loop.  A cnt-alt-del would 
get out of it, then using the SuperGrub2 CD I could get it to boot again after 
adding the LVM option.

I am ready to give up on this and do a reinstall (taking more detailed notes 
next time).  Unless you want me to continue exploring something that would 
assist you.  I probably won't find the time to do the re-install for at least a 
day or so, if you would like additional information.  Thanks again for your 
assistance.

Jeff

The value of $prefix is bogus. It points to ESP (EFI System Partition)
but with non-existing path. One of (hd0,gpt1)/EFI/ubuntu or direct LVM
reference would work.

Quick workaround is to create /boot/efi/boot/grub and copy grub.cfg
from /boot/efi/EFI/ubuntu in there.

Does it work?
