[UNSOLVED] Loading grub2 takes forever

After i recently upgraded grub to grub2, when booting the system,
the following message is visible for about 10 seconds:

GRUB loading.
Welcome to GRUB!

_

After that, there is the grub menu and everythings works just fine. It just takes too long load.
Before the upgrade i couldn't even read that message, because the menu was loaded almost instantly.

Re: [UNSOLVED] Loading grub2 takes forever

I do see that message briefly but nothing like 10 seconds.

Are you booting in bios or efi mode? How did you install grub? What is your grub configuration?

From your grub.cfg it shows you are not using the latest version. When did you do your last update?

What henk said. Though I do not think that will make the menu appear faster. I take it that sda1 is Arch and that you do not have a separate /boot partition. Is that correct?

# (2) Windows 7
menuentry "Windows 7" {
  set root="(hd1,1)"
  chainloader +1
}

And sdb1 is for Windows boot?

Re: [UNSOLVED] Loading grub2 takes forever

Overlooked the following completely

# (2) Windows 7
menuentry "Windows 7" {
  set root="(hd1,1)"
  chainloader +1
}

@MickeyKnox, check the boot-order of the HDD'S in the bios. As far as I know Windows will not boot from the second harddisk if not configured properly.
Maybe Grub is searching on the wrong HDD.

I don't know exactly, maybe one or two month ago.
But i just ran an upgrade and two new issues arose:

1. In the grub loading screen before the menu, i get the following error:

 error: file '/boot/grub/locale/en.gmo' not found

I think i had a similar problem before and i think i solved it by renaming some file.
Apart from presenting me that error everything runs fine though.

2. Powering off the system takes forever now. Before it took like 2-3 seconds, but now
it takes like 30 seconds. After exiting X i'm on tty1, where nothing happens for 20-30
seconds, then there surfaces some text and the system powers off almost immediately.
It looks to me like it waits for something to time out.
I'm not sure if this is related, maybe i should open up another thread for this.

Windows boots just fine. Curiously enough, in the BIOS i can't select sdb as a boot device.
(I have an Asus P5B Mainboard.) And i did some more testing. When i disconnect sdb, everything
stays the same, it doesn't go any faster. (Of course, selecting Windows in the grub menu results in an error.)
When i installed Windows, i disconnected sda so that the Windows installer can't touch it.
That also has the benefit that i can boot Windows without sda and grub.

Re: [UNSOLVED] Loading grub2 takes forever

A few things I notice:

### END /etc/grub.d/40_custom.pacsave ###

Check your /etc/grub.d folder for .pacsave files. This wiki page will explain how to deal with them.
Edit: checked the wikipage for grub; seems I was wrong about the msdos thingie.
Why Windows as a custom entry?

I did merge these files. However, this is rather cosmetic because it doesn't really change
anything; in effect it just removes some comments from /boot/grub/grub.cfg.

That was the suggested way in the wiki.

I found that somebody else had a similar problem with missing files, i'm not sure though
if that has been solved: https://bbs.archlinux.org/viewtopic.php?id=165821

The second problem about the system taking forever to poweroff just resolved itself. Weird.

The grub loading screen before the menu still appears too long though.

This is just a thought, maybe it doesn't matter at all, maybe I'm all wrong.
But with installing Windows in this way didn't you create a MBR on the disk
with Windows on it?  Which would hold the information for booting Windows.
I'm wondering how your windows entry in Grub would look like if you used os-prober
to detect it.

But again, this is just a thought.

Edit: fixed some typos

Re: [UNSOLVED] Loading grub2 takes forever

I really don't think that loading grub takes so long because of my windows installation.
When i disconnect the harddrive with windows on it grub takes the same time to load.

Re: [UNSOLVED] Loading grub2 takes forever

It's not your windows installation that is the problem. The place on the harddisk where the information for booting
your windows installation is stored, could be of importance.
This part of the Grub wiki page does a good job of explaining:

 It is the system partition that has bootmgr, not your "real" Windows partition (usually C:).

Your Grub points to the real windows partition, hd1,1 where in fact it should point to the MBR of hd1. To look at it very simply, Grub searches hd1,1 doesn't find boot
information, searches on, eventually seems to find the MBR on hd1 and is ready.
the same goes when you disconnect hd1. GRUB has an entry to search for, now finds nada and continues.

Re: [UNSOLVED] Loading grub2 takes forever

Ok. I commented the Windows section in /etc/grub.d/40_custom,
regenerated the config file and reinstalled grub. Apart from not
having a windows entry in the grub menu, everything was the same.
Grub still took as long to load as before.

Re: [UNSOLVED] Loading grub2 takes forever

The missing locale error is supposed to have been fixed (https://bugs.archlinux.org/task/35937) if I'm reading the bug report correctly.

There used to be information on addressing this manually in the wiki, I think, but I can't seem to find anything on either the Beginners' Guide or the GRUB wiki pages. (Maybe because it is meant to have been fixed?)

Basically, you can copy a file from /usr/share/locale/en@quot/LC_MESSAGES/grub.mo  to whatever name and location grub expects. (Are you sure it is .gmo and not .mo?)

Re: [UNSOLVED] Loading grub2 takes forever

Thanks cfr, the error message went away. And yes, i'm sure it was .gmo.

The grub loading screen still appears way too long though.
