any help would be apriciated i've been having this problem for a while. thx.

I'm pretty sure that for the boot partition you should use a "true" Linux filesystem like ext2 and not reiserfs. This might be the problem. The handbook recommends ext2 (and this is what I use for boot while I use reiserfs for the / partition).

Code: Select all

/dev/hde3 on / type reiserfs (rw,noatime,notail)
/dev/hde1 on /boot type ext2 (rw,noatime)

Actually wat u said might be wrong i am using a reiserfs for my /boot with no problems.

According to wat gurugemair wrote
The most probable reason is that he hasn't got a proper fstab file and has not mounted the boot partition on /boot
Plz post ur /etc/fstab just in case
Also check that the type of partition u want to use here in built into the kernel and not a module
And mount the boot partition to /boot then try installing grub

gurugemair, in the future please search before you post. It's hard to miss the GRUB error collection [/mod]

Code: Select all

cat: /proc/mounts: No such file or directory

I suspect you forgot to mount /proc. You need to do that before you can run grub.

Thanks shaumux for the correction. That's good to know.

Hi there,
I have a strange partition layout:

Windows- hda1
Linux- Boot hdc1 // Root hdc2

When I install GRUB, I need to put it on the MBR, so I can type:

grub> setup (hdx)

My question is which hard drive do I put for the setup line, the windows or linux one? Thanks!

It all depends on what disk you want to boot from and whether you want to use GRUB as your main boot loader. If you want to boot from the windows disk, then you should install GRUB into hd0. If you want to boot from the linux disk, install it into hd1. By the way, if you boot from the linux disk, be warned that grub will see it as hd0 and not as hd1. So you'll have to adapt the entries in your grub.conf file for that.

I'm using the 2007.0 live cd to install gentoo on my inspiron b120, when I get to the grub install stage, this is what I got:

Code: Select all

 * Linking from new grub.conf name to menu.lst
 * Copying files from /lib/grub and /usr/lib/grub to /boot
 * To install grub files to another device (like a usb stick), just run:
 *    emerge --config =grub-0.97-r3

>>> No packages selected for removal by clean

>>> No outdated packages were found on your system.
 * Regenerating GNU info directory index...
 * Processed 107 info files.
Probing devices to guess BIOS drives. This may take a long time.

Ok guys... been running Gentoo for years... but I just ran into a Grub problem I can't solve.

I have two IDE HD's in master slave... master is a windows drive, slave is linux. I've had gentoo up and running in this configuration for about two years now.

Just today I got a new SATA HD.... so I plug it in and boot up my machine, only to be greeted with:

Code: Select all

GRUB loading, please wait...
Error 5

I have booted from a Gentoo install cd and chrooted over to my Gentoo partition... and gone back through the grub setup process... I tried changing drive numbers around (just in case Grub was seeing them in a different order because of the new drive), but nothing seems to help. I can install Grub just fine onto HD0 and it reports complete success... but always Error 5.

If I remove the drive (or disable my SATA controller) everything boots fine.

Any suggestions?

friedmud · Post by **friedmud** » Fri May 18, 2007 2:49 am

After a bit of messing around, I thought the error might have been caused by the new drive not having a partition table... so I partitioned it and created an ext3 filesystem out of the whole drive.

Unfortunately... now I get "Error 15" which I believe is usually missing files (can't find grub.conf).

Is it possible that while in linux off the install cd... the drives are in a different order than when grub is trying to boot??

When chrooted grub definitely sees my windows drive as hd0 my linux drive as hd1 and the new SATA drive as hd2... but it feels like that isn't the case when grub is booting...

friedmud · Post by **friedmud** » Fri May 18, 2007 3:31 am

Well... I guess I figured it out.

After taking a hunch that the drives were getting reordered when Grub was trying to boot... I modified the device map such that the windows drive was hd0 the linux drive was _hd2_ and the sata drive was _hd1_ then reran grub-install.

This did the trick. I have no idea why grub is putting the sata drive _in between_ the other two.... but it is.

Weird... just weird.

I try to install grub on a Compaq ML370R01 with Gentoo 2007.0 but if fails.

I had to install Grub manually and it seems to boot, but now I got:
!!! Block device /dev/ida/c0d0p3 is not a valid root device...
!!! The root block device is unspecified or not detected

This is the layout of my disks:
/dev/ida/c0d0p1 = /boot (ext2)
/dev/ida/c0d0p2 = swap
/dev/ida/c0d0p3 = / (ext3)

I also created a device.map with:
(fd0) /dev/fd0
(hd0) /dev/ida/c0d0

And this is my grub.conf;
timeout=30
splashimage=(hd0,0)/grub/splash.xpm.gz
title=Gentoo Linux
root (hd0,0)
kernel /kernel-genkernel-x86-2.6.19-gentoo-r5 root=/dev/ram0 init=/linuxrc ramdisk=8192 real_root=/dev/ida/c0d0p3 udev
initrd /initramfs-genkernel-x86-2.6.19-gentoo-r5

Any clue what goes wrong ???

This is not a grub error. This means you forgot to include the support for the cpqarray driver in the kernel <*> and not as a module <M>. Activate the support under Device Drivers ---> Block devices ---> Compaq SMART2 support.

Yep I now understand .. it seems to be module .. but MUST be included in kernel.

mgmguy1,

You make a new file with

Code: Select all

nano -w /boot/grub/grub.conf

rootnoverfity hda,o should be

Code: Select all

rootnoverfity (hd0,0)

to boot from /dev/sda1 if sda is your first or only drive

Hi,
I accidentaly deleted boot partition, than recreated, reinstaled grub, copied bzImage to /boot, but I dont get a splashscreen - only menu very poor readable, after comment in grub.conf I have clean menu (BW), but with error 15: file not found, I tried all advices from Gentoo Grub Error Collection page, but nothing works. Seems to be that loader doesnt have access to /boot directory on /hda4, when I edit the line in grub to - kernel /nameimage root=/dev/hda2 it boots (but than ends on kernel panic)
Is it posible when I reformating boot partition, that some ID of partiotion has changed and needs to be reported to some config file on hda4?

my partitions are
hda1 - ntfs
hda2 - boot
hda3 - swap
hda4 - ext3

Thanks

davascript · Post by **davascript** » Wed May 23, 2007 11:55 pm

Have you reinstalled grub to the MBR using

Code: Select all

grub --no-floppy
root (hdx,x)
setup (hdx)

vitoriung · Post by **vitoriung** » Thu May 24, 2007 2:58 pm

I followed hand book and instaled grub by -

#grub-install --no-floppy /dev/hda

is it the same way, or shut I run #setup (hda) as well?

vitoriung · Post by **vitoriung** » Thu May 24, 2007 5:58 pm

I tried it, but with same result,
in my case I have in grub -

root= (hd0,1)
Filesystem type extfs2, partiotion type 0x83
kernel /boot/kernel-2.6.20-gentoo-r8 root=/dev/hda4

Error 15: File not found

if I edit grub loader by press E to -

kernel /kernel-2.6.20-gentoo-r8 root=/dev/hda2

it boots sucessfully...!!

Any sugestions? If someone really wants to help me now, because I am trying to fix it now and next couple of hours, contact me on ICQ 168844312 or skype - Vitoriung

Thanks a lot..

I assume this is all happening because you didn't copy the contents of the /boot dir and didn't emerge grub again. Thus, you don't have the boot symlink nor the splashimage file - which caused the unreadable screen.
Please run emerge -av grub and post your grub.conf file if it still fails to load your kernel.

I wasted too much time, so I realized to better improove my experience with instalations, and reinstaled all system, anyway it was cleaned before with this X server isue http://forums.gentoo.org/viewtopic-t-56 ... tartx.html

Thanks for help, now I'm back with my "X" problem

ive been searching but nothing fully applies to me so im posting.

im installing gentoo via a vm in vmware 6. i get Error 13: invalid or unsupported executable format. my grub.conf is below

Code: Select all

default 0
timeout 30
splashimage=(hd0,0)/boot/grub/splash.xpm.gz

title=Gentoo Linux 2.6.20-r8
root (hd0,0)
kernel /boot/initramfs-genkernel-x86-2.6.20-gentoo-r8 root=/dev/ram0 init=/linuxrc r$
initrd /boot/kernel-genkernel-x86-2.6.20-gentoo-r8

i have been reading a bunch and at one time removed the /boot from the line but that had no effect. my fstab is also below.

Code: Select all

/dev/sda1               /boot           reiserfs                noatime,notail $
/dev/sda3               /               reiserfs                noatime,notail $
/dev/sda2               none            swap            sw              0 0

#/dev/fd0               /mnt/floppy     auto            noauto          0 0

it all seems to be fine but im a n00b. thanks in advance.

Welcome to gentoo.

Can you tell use what happens when you try to boot and what error message you get ?
