 |
|
Hi i just got done installing gentoo and went through creating GRUB and then rebooted and i didnt get the GRUB menu screen. It automatically booted Win xp. Then i went back into gentoo using the install cd and try to look at the grub.conf and its not there....Can someone explain what i did wrong? or how to get it back? Do i have to go through the entire install again? Any feedback would be greatly appreciated. Thanks
mod edit: split off a post by ooosb that had nothing to do with the thread.

You shouldn't have to do it all over again. Boot from the livecd, mount your partitions - root filesystem as /mnt/gentoo and the boot partition as /mnt/gentoo/boot. If you can't find your Grub files in /mnt/gentoo/boot, try unmounting /mnt/gentoo/boot and see if they're there. It happens that people forget to mount and use the /boot partition, so the Grub files end up in the /boot directory on the root partition.

I think it sounds very much like you just forgot to install grub stage 1, i.e. the MBR entry pointing to where the actual boot loader, grub stage 2, is. Boot from the install CD, do This brings up the grub command prompt. Now type if your boot partition (where the kernel and boot loader and all that is) is the first on the first harddrive, /dev/hda1 in Linux language. For instance, a boot partition on /dev/hdb3 would require you to type To make sure you did this correctly, you can type (and remember that grub supports bash-completion) | Code: | | grub> kernel /<yourkernelname> |
You should not get an error message. Finally, you do if your boot partition is on /dev/hda. This installs stage 1 to the MBR. Note, that if boot sector virus protection is enabled in the BIOS this will not work; you must disable it. That's all, type quit and reboot. |

It is possible grub isn't on the CD. If you have grub installed, you should get the prompt by typing grub anywhere in your system. You must of course be chrooted into your root partition first, though.
I would boot from the cd, and do the following:
| Code: |
# cd / && mkdir -p mnt && mkdir -p mnt/gentoo
# mount -t <your_root_fs> /dev/<your_root_partition> /mnt/gentoo && mount -t <your_boot_fs> /dev/<your_boot_partition> /mnt/gentoo/boot
# mount -t proc none /mnt/gentoo/proc && chroot /mnt/gentoo /bin/bash
# source /etc/profile && env-update
# grub
|
Then follow my previous post. <your_root_fs> is the filesystem type you use in your root partition, such as ext2, ext3, reiserfs, xfs or whatever you use. |

ok i did all that and i got the grub prompt and entered in everything and when i rebooted i still didnt get the menu. i have everything for gentoo on hdb and windows is on hda so is this the correct syntax for the grub part?
grub> root (hd1, 0)
grub> setup (hd1)
Is the setup supposed to be on hdb or is it supposed to be on hda? Thanks |

You might have to reconfigure somethings. Go into your bios and change it to boot to your second drive (grub should come up). Tell us if grub comes up or not, and repost in this thread saying if windows and/or linux will boot using grub that way. If not, I can help you get it all sorted out. Shouldnt need to reinsatll or anything, just edit a few config files.  |

I see I didn't explain this properly; stage 1 should be on the harddrive you boot from first, depending on your BIOS setting. It still has to point to stage 2 correctly, though. If you have Windows on hda I would put that first, otherwise you need to do some additional grub configuration...
To chroot means you enter a system from another OS (like the CD) and start using its environment instead; you set its root directory as the top, source its path etc. If you followed my post above that is precisely what you did.
If by the login you mean the usual bash prompt when the boot process finishes, it says 'localhost' because you have not set the hostname. Edit /etc/conf.d/hostname and do | Code: | | # rc-update add hostname default && /etc/init.d/hostname start |
once you are logged in. You can set your root password by booting from the CD, chrooting into your gentoo like before, and typing 'passwd'. |

It should be in a directory called grub on your boot partition. Mount /boot and cd to /boot/grub/. You should see a grub.conf.
