 Posted: Wed Sep 01, 2010 8:30 pm Post subject: Boot stops at GRUB |
 |
|
Additional Info:
I followed the installation handbook (x86) and I am at the last step which is to reboot. So I go ahead and reboot and take out my minimal installation CD.
The problem:
The computer boots up GRUB to command line with "GRUB>". So if I am correct, this is not so-pose to happen (Kernel is not booting). I must of done something wrong in the grub.conf file.
My question:
How do I access the grub.conf file again? I understand that I must use the live CD once again. I do not know how to access my harddrive files using the live CD. |

You probably need to follow the chapter on the installation of GRUB again.
To access your files you need to mount your partition.
For example: mount /dev/sda1 /mnt/gentoo.
/dev/sda1 is the first partition of your first hard drive.
Use fdisk -l to list your partitions.
After you have accessed your partitions please post your /boot/grub/menu.lst. |

You can just remount them and even chroot back in like when you installed, Example after rebooting livecd:
| Code: |
mount /dev/sda3 /mnt/gentoo
mount /dev/sda1 /mnt/gentoo/boot
mount -t proc none /mnt/gentoo/proc
mount -o bind /dev /mnt/gentoo/dev
cp /etc/resolv.conf /mnt/gentoo/etc/
chroot /mnt/gentoo /bin/bash
env-update && source /etc/profile |
You can of course just stop at mounting your partitions if you don't need to chroot to fix. |

Here is what I have in /mnt/gentoo/boot/grub/menu.lst
| Code: |
default 0
timeout 30
#splashimage=(hd0,0)/boot/grub/splash.xpm.gz
#tittle Gentoo Linux 2.6.24-r5
#root (hd0,0)
#kernel /boot/kernel-genkernel-x86-2.6.24-r5 root=/dev/ram0 real_root=/dev/sda3
#initrd /boot/initramfs-gebkernel-x86-2.6.24-gentoo-r5
#vim:ft=conf:

I'm no expert but # is commenting out. |

yes remove the # at the beginning of each line and check if it works now.

First, remove the # characters from the four lines starting with tittle, root, kernel, and initrd. Like the previous poster said, they mean that everything after them on a line is a comment, and is ignored by GRUB.
Second, change the spelling of tittle to title. (I.e, lose the extra "t"). It's a keyword, and GRUB will complain if it's spelled wrong.
Third, and optionally, you can uncomment the splashimage line if you want. It just makes the boot menu look nicer, but is not an error if it's commented out with the #.
Hope this helps you.
EDIT:
Oh yeah, and update the paths to your kernel and initrd to match your actual ones in /boot. Same goes for your real_root partition.

simply removing the comments will be insufficient, as it is unlikely you have a 2.6.24 kernel sitting on /boot
you will need to uncomment AND adjust the paths accordingly.
after you built your kernel, there should have been a step that had you 'cp arch/x86/boot/bzImage /boot/<somefilename>'
did you follow this step?
If so, you will need to update grub.conf to point to whatever file name you gave the copied bzImage.
My grub.conf as an example:
| Code: |
default 0
timeout 10
splashimage=(hd0,0)/boot/grub/splash.xpm.gz
title Gentoo Hardened (2.6.29)
root (hd0,0)
kernel /boot/kernel root=/dev/sda3
|
after I built my kernel with make && make modules_install, ensuring /boot is mounted, I:
| Code: |
cp arch/x86/boot/bzImage /boot/kernel
vi /boot/grub/grub.conf
<edit it to look like the above, and save>
|
So your problem is twofold:
-you have everything commented out
-the commented portions need to be updated to point at your kernel, and optionally, your initramfs if you used one.
Have a re-read of the "configuring your kernel" portion of the handbook, as well the "configuring a boot loader" section, seems ya missed a few spots!

He might have used genkernel to build and install his kernel. It's in the handbook. Either way, yeah, he needs to edit the paths to match. |
