I am using Ubuntu Server as a SMB server at work and two days ago I have tried to upgrade it to 12.04.
After reboot, I got this
grub_xput missing grub rescue>
and all attempts to start from this prompt failed (missing components, although grub directory is normally set as prefix).
My system sits and boots on an LVM (soft raid-5).
I have read almost all posts in many forums, tried
boot-repair but without positive result.
This is the log of my last (and best so far) attempt to fix this system.
Any suggestions? Please help.
