GRUB geom error

[kansasnoob]

From the Live CD you should be able to:

sudo mount /dev/sdc6 /mnt && sudo mount --bind /dev /mnt/dev &&sudo mount --bind /proc /mnt/proc && sudo chroot /mnt

grub-install /dev/sdc

If that shows any errors then:

grub-install --recheck /dev/sdc

Then exit, unmount, and reboot:

exit

sudo umount /mnt/dev && sudo umount /mnt/proc && sudo umount /mnt

sudo reboot

I do this but it gives always to me that error.look yourself...

[kansasnoob]

OK look here:

http://sourceforge.net/apps/mediawik..._For_boot/grub

If that doesn't work I still have one more trick up my sleeve

I've done both.the first gives me an error, the second seems to load something but after 10 mins has not ended yet...uff i'm unable!!!any other suggestion?thanks!!!

[kansasnoob]

Just happened to think I wasn't very clear. Referring to that last link when it says:

Install grub via

sudo mount dev/sdXY /mnt
sudo grub-install --recheck --root-directory=/mnt /dev/sdZ

"sdXY = sdc6"
"sdZ = sdc"

And you don't have a separate /boot partition or a a custom designed device.map.

So the next step is to revert your external drive to legacy grub, but I would like to have you run the Boot Info Script again and post the new results.

[stefano91]

Plese can some one help me?is there a command ti know where is rhe problem?or i have to do something else?thank you very much!

You are past boot problems and into something on your system not working correctly. We need to know the last command it tried to run from the recovery boot.

Did your system boot ok from the liveCD? Sometimes added parameters are needed to get a video card to work.

Others with slow boots have solved them this way.

yes from Cd it boot perfectly!and also from windows.it also find the grub and find the ubuntu installation.but when there is the loading with the bar under the writing "ubuntu" the lighting ball of loading bar stops after a few second.and nothing else happen.and i can't see the motivation...
