Grub Rescue

The following text is reference from this blog article.

The original text is Chinese. I translate it into English

I originally got a SATA II Hard Drive and installed a Ubuntu 10.10 on it.

And for some unknown reason. It won't show the grub menu.

Then I choose install another Ubuntu on another disk and the 2nd Ubuntu is smart and can let me get my 1st Ubuntu

But after that I found there are too many software need to be re-install & configure

I decide to go the hard way.

The error message is

No such a device

I have no idea what should I do then.

After googled from that blog article.

I follow his instruction and unattach my 2nd hard disk and do the following:

grub rescue>set
prefix=(hd0,msdos1)/boot/grub
root=hd0,msdos1






This seems correct, then I do


grub rescue>ls
(hd0), (hd0,1)



I got only one partition, so I can startup via the 1st partition

grub rescue>set root=(hd0,1)
grub rescue>set prefix=(hd0,1)/boot/grub
grub rescue>insmod normal
rescue:grub>normal



Then I can see my grub menu(Long time no see)

Then I got a normal startup (No more extra hard disk)

After in the GUI of Ubuntu, now need to modify the 
/boot/grub/grub.cfg

run update-grub to update the grub menu
sudo update-grub

now reinstall the grub

sudo grub-install /dev/sda

restart again. my 1st Ubuntu is back :)
