What is the exact error you are getting?
Something along the lines of
UUID 2b82edc2-4eb2-44a0-8b5b-c71da0de9b3a not found.
With the hard disk only does it find grub and does it display a menu
or drop you to the grub> prompt?
I get the grub prompt.
If it displays a menu and you select one of them what does it then do?
No menu.
The uuid will also be on the kernelopts line, but if that was the
error you would have failure to mounted root after the kernel tried to
boot.
The offending UUID is listed in the grub.cfg file in seven places.
Not sure what that tells you.
Apparently grub can find sda3/boot/grub2/grub/cfg
even though grub rescure can find no partitions, just (hd0).
all of the commands would need to be run in the chroot setup (after
the chroot . and before exiting chroot-mainly the grub2-mkconfig that
updates grub.cfg and the grub2-install for /dev/sda.
I would stay away from the centos boot, nothing it can do will be good
since you are running a newer grub setup. It is better to use newer
livecds than older ones (ie I f27 all of the time to rescue el5/6/7
version and chroot into the actual machine to be fixed environ after
mounted it all).
After chroot I should get the grub stuff from sda3 , correct?
My DVD machine no longer likes my F33 DVD.
I'll need to make a new one.
Is there a way to tell grub rescue to
reboot without pressing the power button?
