 Posted: Wed Apr 11, 2012 12:29 am Post subject: New install issues |
 |
|
Hello,
This is my first time installing gentoo, and it sure has proved to be a learning experience. I finally got it to boot into the grub after 3 attempts before. I searched around on google for a little bit and eventually was able to manually load the kernel and get to the log on screen of my gentoo installation. I was all excited until I tried to follow some guides on how to fix my original boot problem.
Here is my first issue, hopefully its fixable without starting over. I was told to edit my grub.conf file for the grub to know what to boot....only problem is /boot/grub/grub.conf is not there.
/boot/grub is not there.... /boot is actually empty...as far as i can tell (typing ls /boot shows nothing). Anyone know where I can begin with this?
(i have searched around on these forums for about 30 minutes, im sorry if this has already been worked on, I was unable to find it in that amount of time)
Thank you in advanced for anyone who takes the time to help.  |

ravelink69,
The boot partition is not automatically mounted - it's set in fstab noauto,noatime if you followed the installation instructions.
To gain access:
That will mount it and then you'll
to check the contents  |

Thank you for the info. Unfortunately i get the following when i type mount /boot
| Code: | mount: /dev/sda1 already mounted or /boot busy
mount: according to mtab, /dev/sda1 is mounted on /newroot |
My linux knowledge is obviously not very indepth, but that is why i am hoping to learn a lot from this. |

for some reson, /boot looks like it was mounted on /newroot
try ls /newroot and if that looks like /boot then nano -w /newroot/grub/grub.conf should give your grub file for editing. One wonders what it is doing under /newroot though....

ravelink69,
It's stating that it's already mounted, but not on /boot
Paste back the contents of fstab.
Also did you try to mount anything  |

I believe BillWho meant the output of cat /etc/fstab (he would only need the uncommented lines; that is, lines not starting with a # symbol). |

ravelink69,
What you should do is chroot from a live cd of your choice like mint, ubuntu etc. or systemrescue. This way you can gain access to the forum and be able to copy and paste. Working from the console will be tedious and limit your capabilities.
Since ls /newroot did not work, there's something else going on here and knowing the contents of your /etc/fstab would help.
To view fstab you would enter
as kurly alluded to. Working from the live cd you could then copy and paste it back here |

Sorry about that. I have the computer next to me but i have now logged in via ssh.

ravelink69,
OK, ssh is another good option. As far as fstab is concerned - it looks OK. So where is this newroot coming from 
Try
and look for this mysterious /newroot. The column -t just formats the output - it makes it look a little nicer.
If /dev/sda1 does not show in the output then try again and see what happens |

| Maybe this had to do with the fact that I had to manually start the kernel in gub. Possibly I did something wrong there? |

Your guess is better than mine because I don't have one I'm totally confused here 
paste back

What did you do to manually start the kernel |

SElinux issue?
In any case, try using a live CD. It will NOT mount anything until you tell it to. then you can remount your partitions and edit grub. If you need to emerge anything or run grub-install, then remember to chroot.

ravelink69,
I would chroot as penguin swordmaster suggested. I'm going to guess that you didn't boot the kernel on /sda1 
I think the following is correct - just double check it
| Code: | mkdir /mnt/gentoo
mkdir /mnt/gentoo/boot
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
chroot /mnt/gentoo /bin/bash
env-update
source /etc/profile
export PS1="\[\033[1;33m\]chroot to ->\[\033[1;31m\](gentoo) #\[\e[0m\] "
|
I'm sure newroot will not reappear |

ravelink69,
You should have access to the boot directory so you can correct your grub entry.
Chrooting to your installation is almost like booting to it.
Try mount|column -t again and see what you get - hopefully no more newroot |
