Today i have updated system from dahsboard. The updates include a new kernel (2.6.32-33) so i need to reboot.
On reboot, grub fail with:
Error: symbol not found: 'grub_putchar'
grub rescue>
Fortunately, i have an alternate boot disk with an Ubuntu 10.04 for recovery puposes on an USB drive.
Booting fron that disk and updating the USB disk GRUB, i can boot the main disk from USB drive GRUB.
With system up, i can do update-grub with no error, but rebooting with main disk grub, i still get same error.
I have not found a clear solution on the net, so any advice is welcome.
Thanks
PD: here is my /boot/grub/grub.cfg:
