Did you definitely mount “dev”? ie the line:
sudo mount -o bind /dev /mnt/dev

Had to google my own post as I ran into this problem again, and I need the line you mention. Added it to the article, thanks!

Binding your /sys environment will also help in situations where you’re trying to load many different OS’s (especially Windows)

sudo mount -o bind /sys /mnt/sys

Thanks for the heads up. Had actually spotted it the other day when I noticed my traffic dipping. It’s the infamous Pharm Hack that has hit many WordPress sites. I think I’ve cleared it out now, am just waiting for Google to re-index my site.

HI Robert, I found your post on google but the result that was returned was strange to say the least.

I don’t want to put the exact phrase in but suffice to say that the title of your page in the google results list was like this:

Buy A Prescription Drug | Robert Beal

Along with that the text snippet that was displayed was text from your site interspersed with the name of the drug they are flogging.

I come to your page and there is no sign of the stuff that shows up in the google results.

The search I did was “rebuild grub” and the result was third in the list.

If you look at the google cached version of your page it is littered with references to the drug.

Somehow your google results have been poisoned, but I don’t know how.

Thought you might like to know

Hmm, that is odd. What distro are you running? Ubuntu? And also what version?

sorry these commands doesn’t work accurately.
after reboot no grub list appear , it directly takes to me grub promt.
when i search for menu.lst or grub.cnf file in grub promt it displays file not file.

I tried this and got an error like “Cannot find list of partitions”. Based on http://www.linuxquestions.org/questions/linux-general-1/altered-partition-table-grub2-will-not-load-how-to-chroot-699424/, I fixed it by doing this additional bind operation:

mount -o bind /sys /mnt/sys

After this update-grub worked perfectly.
