Grub Prompt

I was updating my menu.lst file  and then thought I had to run grub-install so I ran the following command

sudo grub-install --root-directory=/boot hd0

No Errors.

But when I rebooted I was presented not with my menu.lst, but the GRUB prompt.

I manually ran the menu.lst commands into grub and then booted successfully.

But every time that I reboot I get the grub prompt.

I have a separate boot partition on /dev/sda1 (I only have one hardisk).

Re: Grub Prompt

Firstly, you don't have to run grub-install after editing menu.lst.

If anything is displayed before the grub prompt appears, post it, along with your menu.lst and your partition table.

And just for clarity - entering commands at the grub prompt has no effect on menu.lst.

I do understand about the grub prompt. I am becoming better and better at it.

Re: Grub Prompt

I figured it out.

My problems first started by following the arch wiki . . . GRUB Install

The wiki states:

"If you have a separate boot partition mounted at /boot, do one of the following"

grub-install --root-directory=/boot '(hd0)'

This is wrong, by running the exact command above I created a second boot directory under my "real" boot directory

/boot/boot/grub

Obviously my menu.lst would not be in the new boot directory. As soon as I moved my menu.lst file into /boot/boot/grub it began to work.

I then moved the files and directories around a bit, and then ran the correct command

grub-install hd0

Then rebooted. This command worked perfectly(as it should).

I am changing the wiki page (linked above) to fix this error. If I have come to the wrong conclusions please feel free to re-edit the wiki.

Thanks everybody, here and on irc for the help.
