Hi

,
I don't know if the update cause the problem but yesterday I did the update (yum update) but it is only this morning I did (signal-event post-upgrade; signal-event reboot) then the Grub problem occurs.

When I boot a have this message:
GNU GRUB version 0.95 (615K lower / 1571840K upper memory)
[Minimal BASH-like line editing is supported.
For the first word, TAB lists possible command completions.
Anywhere else TAB lists the possible completions of a device/filename.]
Grug>_
What I have to do to recovery?

I know nothing about Grub (I think I will begin to learn something today

).
