autoload grub.conf

Timmer · Posted: Mon Dec 20, 2004 1:23 am Post subject: autoload grub.conf

I'm not really sure what to call this problem so it was hard to search for it. But anyway, I must have done something to grub awhile back. It loads in shell mode, so that to boot i have to type

kernel ...
boot

Now, this isn't really difficult, but after about a month of it, I'm tired of doing it and want it to autoload the config file again b/c that's easier. How do i do it?

This is because you haven't installed it on the MBR. You do this like so:

That didn't do it. When i did those commands, everything was fine, no errors; but i still have to load the kernel manually.

(And yes, before anyone asks, my /boot is at (hd0,0).)

You have to do that after you boot your system.

I got that (and that i had to do it as root) from the # prompt, but thanks for the suggestion.

How many hdd's do you have? Or is it possible to have grub installed on a partition too?

your grub configuration for every linux boot option should have a kernel boot command listed. if that's the case, then you don't have to type it manually. again, please post the contents of grub.conf.

Your grub.conf should look like this:

Okay well, i've tried both of those but neither of them worked. But i'm pretty sure the problem is not with grub.conf b/c the file isn't ever getting loaded. If the computer never reads the file, the file can't screw things up.

just to be thorough, you're reinstalling grub onto the boot sectors after every edit of grub.conf, right?

Timmer, I don't understand why you're sure, that grub.conf is not loaded, can you explain me this? Do you have any hint, what you did to grub before this problem occurs?
Bob P, why reinstalling grub after editing grub.conf? This is not lilo...

I've never had any problems after editting grub.conf without reinstalling grub before, so i hadn't been doing that. And since there's someone that agrees with me that it doesn't need to be done, i'm not going to bother.

And no, unfortuneately, i don't remember what it was that i changed or anything. Like I said, it was a month or 2 ago and since the work around was only a minor annoyance, i didn't take note of what i did to "break" it. I remember it having something to do with the installation instructions in the gentoo handbook. It may have been that there was a grub update on portage i was re-installing grub as a result or something.

hmm. just checked my portage tree on that thought and discovered that while i have sys-boot/grub-static installed, i don't have sys-boot/grub. I'd install it, except that the computer in question is my school computer, and thus, since it's home, it has no internet connection. Anybody think that might be an avenue worth persuing in Jan when i get back to school?

oops, forgot to address a question. I'm sure grub.conf isn't loading because I can load it from the command line. And if I do so, it works. I select my kernel from it, and it will boot just fine, i can go back to the command line, or edit grub.conf from it. So, since my grub.conf works just like it's supposed to, as long as I load it myself, I figure the computer isn't loading it.

Is there something i'm missing that makes that reasoning unsound?

I had the same problem; on boot it didn't seem like my grub.conf was loading from /boot/grub/grub.conf

I examined how this /boot directory differed from a working /boot directory.

On the working computer, inside /boot there was a system link boot -> .

So I made that.

Now it loads fine

what I did:

Timmer, grub-static instead of grub changes everything. So far as I can see, grub-static is only related to AMD64 (I'm on x86, so I cannot help any further...), please search within this forum for grub-static. If you are not using an AMD64, I'm really wondering...
But please read the documentation for you architecture before emerging/unmerging a bootloader.

Hth,
stettler
