 Posted: Tue Apr 19, 2005 10:45 pm Post subject: Gentoo doesnt boot atomatically, always GRUB prompt [solved] |
 |
|
Hi there!
I first posted this message in the Grub error collection but somehow i felt it wasn't read...
Anyhow here my problem:
When booting I always get into the Grub-prompt. I have to
| Code: |
#grub> kernel /kernel-2.6.11-gentoo-r6
#grub> boot
|
to start my system.
I've read about several other people having problems with the same sympthom but the sollutions that worked for them don'e do their job for me.
I've followed the Gentoo Installation Guide 205.0 1:1. I've got:
hda1 boot
hda2 swap
hda3 root
1:1 fstab file
genkernel
After emerging and installing grub (1:1 like in the Install Guide) I left the chrooted environement, unmounted everything and rebooted.
I checked:
| Code: |
# cd /boot
# ls -l boot
# lrrwxrwx 1 root root 1 Apr 17 16:46 boot-> .
|
Symlink form menu.lst to grub.conf seems OK too.
My grub.conf looks like the one in the guide but without splash-image and without windows:
| Code: |
default 0
timeout 30
title=Gentoo Linux 2.6.11-r3
root (hd0,0)
kernel /kernel-2.6.11-gentoo-r3 root=/dev/ram0 init=/linuxrc ramdisk=8192 real_root=/dev/hda3 udev
initrd /initrd-2.6.11-gentoo-r3
|
Neither setting up grub thru grub-install ... nor
| Code: |
#grub
#grub> root (hd0,0)
#grub> setup (hd0)
#grub> quit
|
works
I've read the whole GRUB error collection thread, some documentation about grub and several other sources.
Has anyone an idea what I should try next?
Maybe I've not posted all things I tried...
Thanks in advance!
EDIT: some spelling

|
|
1. I have found that not putting all that stuff after the kernel to fix some problems. I just use:
| Code: | | kernel /kernel-2.6.11-gentoo-r6 root=/dev/hdc3 |
of course you'll need to specify the initrd stuff.
2. go over your grub.conf with a fine tooth comb. Make sure that you are infact using (hd0, 0) (meaning the HDD is hdo and not called something else) and that you are in fact using the proper kernel/initrd name. (I have a raid server that dislikes grub for some reason so I use lilo on there, works fine and that might be a consideration for you).
The problem with looking in boot for the kernel is that that device is not mounted after you boot. So to look in there you'd have to:
| Code: | | mount /dev/hdxx /boot |
Then cd in there and look around.

Try symlinking /boot/grub/menu.lst to /boot/grub/grub.conf: | Code: | # cd /boot/grub
# ln -s menu.lst grub.conf |

@bignate:
OK, I changed my grub.conf one time to:
| Code: |
default 0
timeout 30
title=Gentoo Linux 2.6.11-r3
root (hd0,0)
kernel /kernel-2.6.11-gentoo-r3 root=/dev/hda3
initrd /initrd-2.6.11-gentoo-r3
|
and one time to this:
| Code: |
default 0
timeout 30
title=Gentoo Linux 2.6.11-r3
root (hd0,0)
kernel /kernel-2.6.11-gentoo-r3 root=/dev/hda0 <--here is the difference
initrd /initrd-2.6.11-gentoo-r3
|
running
| Code: |
#grub
#grub> root (hd0,0)
#grub> setup (hd0)
#grub> quit
|
after each change and booting didn't solve the problem.
boot is mounted after booting and the grub prompt seems to have no problems reading from it either.
@codergeek42:
In my first post I stated that the link was OK but I typed down your commands anyway with the result:
| Code: | | ln: 'grub.conf': File exists |
Any other ideas? |

That means that it's on the device /dev/hda and the first (1) partition

|
|
I'm having the same problem on one of my systems, only it just started about a week ago after a month or more of properly displaying the boot menu. I edited menu.lst to add a custom splash image, and that worked once or twice; but ever since, it has given me the grub prompt instead of the menu. Yes, the symlink exists and is correct.
Is that grub's response to a typo in the config file? Although I've scanned it and everything looks as it should.

@Lancet
Please post your fstab file
you might want to change the grub.conf from
| Code: | | kernel /kernel-2.6.11-gentoo-r3 root=/dev/hda0 |
to
| Code: | | kernel (hd0,0)/kernel-2.6.11-gentoo-r3 root=/dev/hda0 |

@bignate
I made a typo earlier. I've got hda1 there:
| Code: |
kernel /kernel-2.6.11-gentoo-r6 root=/dev/hda1
|
@dellaxim
inserting (hd0,0) didn't work
fstap (had to copy that by hand):
| Code: | /dev/hda1 /boot ext2 defaults,noatime 1 2
/dev/hda2 none swap sw 0 0
/dev/hda3 / reiserfs noatime 0 1
/dev/cdroms/cdrom0 /mnt/cdrom auto noauto,user 0 0
none /proc proc defaults 0 0
none /dev/shm tmpfs nodev,nosuid,noexec 0 0 |
...this is frustrating

if I'm not mistaken, you should change
to
in the kernel line, so it would look like this:
| Quote: | | kernel (hd0,0)/kernel-2.6.11-gentoo-r6 root=/dev/hda3 |
I don't know whether this is any new to you, but you may give it a try
good luck |

run these commands for us, this oughta tell us some stuff
| Code: |
mount /boot
ls -la /boot
ls -la /boot/grub
cat /etc/fstab
|
also, just run do this for grub installs
| Code: |
cp /proc/mounts /etc/mtab
grub-install /dev/hda
|
that will install grub and all you gotta do from that point on is edit the config.

I did this every time I changed something:
| Code: |
cp /proc/mounts /etc/mtab
grub-install /dev/hda |
And after it didn't work I tried the manual grub installation.
Here the output you requested:
| Code: | my-computer root # mount /boot
mount: /dev/hda1 already mounted or /boot busy
mount: according to mtab, /dev/hda1 is already mounted on /boot
my-computer roo # ls -la /boot

As sonn as my gnome is merged I'll try that.
(changing root in grub.conf to hda3)
But I think I already did that. I'm just not sure anymore. |

here is what you can try, this could tell us if there is a problem with grub finding the script.
when in grub prompt on boot type
| Code: | configfile (hd0,0)/grub/grub.conf
|
^ you can tab most of that through.
if this works, then your problem is that grub doesn't see your config file, and in which case you may want to rm grub.conf and grub.lst and rewrite it and then re-run the grub-install because i believe the manual install doesn't tell grub where the config is. probably wrong.

@ hogosha
| Code: | | configfile (hd0,0)/grub/grub.conf |
This makes the screen blank and than rewrites the grub prompt.
Except that nothing happens.
I'll try to delete all grub related stuff an remerge it.
@ snuut
Changing root in grub.conf from hda1 to hda3 didn't help . |

OK. it works now.
I still don't know what went wrong the first time.
But after doing the following it worked:
# merge --unmerge grub
# cd /boot
# rm -rd grub
# merge grub
Rewrote the grub.conf with the non-genkernel version but with initrd.
Removed fd line in /boot/grub/device.map
# grub-install /dev/hda
I'm happy that it finally works but I also still wonder what was wrong earlier... 
BTW should I add "solved" to the name of the topic??? |

I tried running the configfile command from the prompt when I rebooted today, and it immediately brought up the menu. I also tried 'grub-install /dev/hda', but that didn't make the menu come up.
I edited grub.conf one more time, to see if I could find any syntax errors. I didn't, but I did find an entry I had commented out a long time ago, to 'Install grup on the hard disk'. I uncommented that and selected it after a reboot (after manually loading the menu again). It flashed briefly, then came back to the menu screen. After another reboot, it booted directly into the menu!
For the terminally curious, that entry simply runs the following:
| Code: | root (hd0,0)
setup (hd0) |
So my problem is now solved, too.

what striked me odd is that your grub-install did not work. i have never had a problem with that, im curious is to what errors if any it gave you.

No error. It looked normal. Otherwise I would've known something was amiss.

I installed Gentoo earlier on the same system and grub-install didn't work then either.
Just like mentioned in the insatll-handbook I set it up manually afterwards and it worked like a charm. |
