GRUB Issue (Given Prompt, Dunno What To Do)

***Cabhan*** · 04-28-2005

Hi everyone. I am now reporting from Knoppix, with Gentoo all configured.

Anyway, after doing all of the configuration, I rebooted and was unable to do much of anything. I ended up in a prompt that was:

grub>

And I could enter options like "boot" (which told me I had to load a kernel first), "kernel" (which told me I need a definite path, but nothing is mounted), and such things.

I tried the options, using both definite paths and GRUB paths.

My mount points are:

/dev/hdb2 [hd(1,1)] = /boot
/dev/hdb4 [hd(1,3)] = /

My grub.conf is as follows:

Code:

# Which listing to boot as default. 0 is the first, 1 the second etc.
default 0
# How many seconds to wait before the default listing is booted.
timeout 10
# Nice, fat splash-image to spice things up &#58;&#41;
# Comment out if you don't have a graphics card installed
splashimage=&#40;hd1,1&#41;/grub/splash.xpm.gz

title=Gentoo Linux 2.6.11-r3
# Partition where the kernel image &#40;or operating system&#41; is located
root &#40;hd1,3&#41;
kernel /kernel-2.6.11-gentoo-r3 root=/dev/hdb4

# The next four lines are only if you dualboot with a Windows system.
# In this case, Windows is hosted on /dev/hda1.
title=Windows XP
rootnoverify &#40;hd0,0&#41;
makeactive
chainloader +1

Ahhhh!!!

Fortunately, I am running in Knoppix, which is definitely the greatest Gentoo-boot option ever. Thanks to you all for helping me with the boot, and if you can fix this, I'll love you all forever!

To avoid confusion, I have deleted my last post.

Now then, my grub.conf currently looks like this:

Code:

# Which listing to boot as default. 0 is the first, 1 the second etc.
default 0
# How many seconds to wait before the default listing is booted.
timeout 10
# Nice, fat splash-image to spice things up &#58;&#41;
# Comment out if you don't have a graphics card installed
splashimage=&#40;hd1,1&#41;/grub/splash.xpm.gz

title=Gentoo Linux 2.6.11-r3
# Partition where the kernel image &#40;or operating system&#41; is located
root &#40;hd1,1&#41;
kernel /boot/kernel-2.6.11-gentoo-r3 root=/dev/hdb4

# The next four lines are only if you dualboot with a Windows system.
# In this case, Windows is hosted on /dev/hda1.
title=Windows XP
rootnoverify &#40;hd0,0&#41;
makeactive
chainloader +1

There have been a few changes made:

"root (hd1,3)" to "root (hd1,1)"
"kernel /kernel-2.6.11-gentoo-r3" to "kernel /boot/kernel-2.6.11-gentoo-r3"

I am still getting this crazy prompt.

Does anyone know what to do? Thanks in advance.

EDIT:

Also, if it matters, I have GRUB installed on /dev/hdb, as my Linux partition is here. Should this be hda?

Try this at the grub>

Code:

find  /grub/stage1

The result should be (hd1,1)
Then type

Code:

root &#40;hd1,1&#41;

Then type

Code:

kernel &#40;hd1,3&#41;/kernel/

and hit TAB

That should bring up a list of stuff, look for the name of your kernel in there.
Put it after kernel.
Now you can type boot and ENTER
I took this info from Nerderello's Grub tutorial.
Hope this helps.

P.S. You didn't use genkernel did you?

When I had a phase with gentoo (I found Portage to be very Intriguing, so I had a go with it), I found LILO to work best, it's better if you want to use a framebuffer aswell.

Code:

emerge lilo
nano -w /etc/lilo.conf
/sbin/lilo

No, I didn't use genkernel.

And I managed to fix some things. I can now boot into Gentoo from GRUB, but I have to type in all the commands by hand. I have to type:

root (hd1,3)
kernel /boot/kernel-2.6.11-gentoo-rc3
boot

So my new question is getting the graphical menu...

I have the menu.lst symlinked to my grub.conf. My new grub.conf is:

Code:

# Which listing to boot as default. 0 is the first, 1 the second etc.
default 0
# How many seconds to wait before the default listing is booted.
timeout 10
# Nice, fat splash-image to spice things up &#58;&#41;
# Comment out if you don't have a graphics card installed
splashimage=&#40;hd1,1&#41;/grub/splash.xpm.gz

title=Gentoo Linux 2.6.11-r3
# Partition where the kernel image &#40;or operating system&#41; is located
#root &#40;hd1,1&#41;
#kernel /kernel-2.6.11-gentoo-r3 root=/dev/hdb4
kernel &#40;hd1,3&#41;/boot/kernel-2.6.11-gentoo-r3 root=/dev/hdb4


# The next four lines are only if you dualboot with a Windows system.
# In this case, Windows is hosted on /dev/hda1.

How do I get the graphical bootloader?

EDIT:

And tuvok, I've used LILO before in Mandrake. Personally, I find GRUB's config file easier to understand, and I prefer its appearance. If necessary, I will switch to LILO, though.

You may want to try this. I ran into the same problem, and for some reason, this worked.

In menu.lst, look for:

Code:

color white/blue black/light-gray
default 0
timeout 20
gfxmenu &#40;hd1,1&#41;/boot/message

and change to:

Code:

gfxmenu &#40;hd1,1&#41;/boot/message
color white/blue black/light-gray
default 0
timeout 20

I had similar issues with GRUB, so I gave up and went back to my LILO

.
Here's some of my *Linux LILO config modified for your needs.

image=/boot/kernel-2.6.11-gentoo-rc3
label="gentoo"
#Correct this if it's wrong.
root=/dev/hdb3
#You don't really need this, but it looks alot better with a framebuffer.
#Change Resolution, to your monitor's.
