 Posted: Sat Jan 22, 2005 11:46 pm Post subject: GRUB menu disappeared. Please help. |
 |
|
I screwed up my /boot yesterday.
I managed to fix almost everything.
After using the LiveCD to make a new filesystem in /boot. Then following the handbook with grub installation after copying over the kernel to /boot.
I did an emerge -C grub, then emerge grub. Made a new grub conf.
Now when I reboot the system, I get no menu. There is only the grub prompt. If I type in all the commands to boot gentoo, it works. How do I get the menu back?

dj_farid,
You need to reinstall grub too. Grub cheats for loading. When you install it, it creates a block list of where some of the files in /boot are so that it can use the BIOS to load them. Remaking /boot will have moved them around, so the files will not be where grub is looking.

I don't understand what you mean.
My /boot partiton got wiped out completely.
I re-made it. emerge -C grub. Emerge grub. New grub.conf. Then "grub-install --root-directory=/boot /dev/hda".
Why does the grub faq talk about /boot/grub/menu.lst? I have always used /boot/grub/grub.conf before as according to the handbook. Is this only for older versions of grub, or something true only for gentoo?
The most important question: How do I fix my menu? |

dj_farid,
It looks like you have done all the right things. The menu.lst symbolic link points to grub.conf and you should not need it. (Thats menul.Lst with a lowercase 'L'). Give it a try though.
When you install grub it puts several files into /boot/grub, using the ordinary filesystem manipulation commands, supported by the kernel.
When it reads these files at boot time, the kernel is not loaded and the filesystem is not mounted. Grub has to make other arrangements.
You appear to have too many boots and it looks like they are both real. The actual boot should contain a symbolic link to . thats back to itself. You said:-

drwxr-xr-x 3 root root 1024 Jan 23 00:20 boot/ should be a symbolic link, or missing altogether. Its no longer clear to me where your grub.conf is?
In /boot/grub/ or in /boot/boot/grub ?

Yes I thought that I have one boot too much. I tried to reisntall grub one more time, but it makes the same thing. The structure looks like this:
| Quote: |
/boot/boot/boot/grub
------/grub
|
I don't understand why it does like it does. My /boot was empty before I installed grub.
I put my grub.conf into /boot/grub

It contains a symbolic link to itself called boot.
It contains a directory called lost+found which only appears on real partitions. You don't have that on your first post, from which I conclude you installed grub into the directory /boot on your root partition because the boot partition was not mounted.
