rich4,
You need:-
title=Gentoo
root (hd .... where gentoos kernel andinitrd are, in grubspeak
kernel ...full path name of kernel and kernel options like root=
initrd full path anme of initramfs, if you use one

| That error indicates that grub is unable to locate a file as specified in its configuration. Verify that all of the relevant partitions are where you expected, then check the file names specified in the configuration file against those present in the relevant partition. As to which partitions to specify, check the /etc/fstab files from each system for their layouts which you can then translate into the nomenclature used by grub. |

rich4,
Error 15 shows that grub started but cannot find one or more of the files you asked it to load.
If you see the image behind the grub menu, its not the splashimage file
Check your kernel and initrd files are on the partition indicated by the root (hd...
and that the file names match *exactly*. Linux is case sensitive.

rich4,
You can put the kernel file and initramfs file anywhere as long as grub can read them
Its customary to put kernels and initrdramfs files into one shared /boot when you have multiple distros installed.
It can then be mounted in any distro.
Its also normal to share swap space, since you can only run one distro at a time.
Show us ls -l /boot, and tell us which device it is.
Paste the content of your grub.conf too.

I considered a boot partition while setting up to install gentoo; I decided ext3/swap was simple enough for learning one thing at a time. But what is this about a /boot folder? Do you have a kb entry about it?
I don't share the swap space reason being so I can hibernate out of one distro and still be able to log into the other.

rich4,
Your current setup can never work. Let me explain a little of the boot process. First my understanding of your install.
You have Ubuntu and Gentoo both installed in their own space.
Ubuntu uses /dev/sda6 for its root
Gentoo uses /dev/sda2 for its root.
Grub is installed to the MBR of /dev/sda
There is no separate /boot partition.
At power on the BIOS does the Power On Self Test (POST) then loads sector 0 (the MBR) of /dev/sda. Thats grubs stage 1.
Stage 1 loads stage 1.5, which uses some of the lost sectors frm sector 1 to 62. stage 1.5 can read exactly one filesystem type. It reads stage2 from /boot/grub. stage2 looks for menu.lst which on Gentoo is a symbolic link to grub.conf. It may be a real file on Ubuntu.
When you only have a single distro, all this just works. With two or more distros, which /boot/grub is read?
They all have one. The answer to that is its whichever one installed grub to the MBR, which for you was probably Ubuntu.
So only the booting instructions on /dev/sda6/boot being used.
The way around this is to make /boot its own partition that is mounted with both Gentoo and Ubuntu. This gives you a single location for all your boot files and more importantly, a single grub.conf (menu.lst) to be read at boot time. As you don't have this, add the instructions to boot Gentoo into Ubuntus grub.conf (menu.lst). You can leave the kernel and initramfs where they are. The root (hd... statement will tell grub where to look.
Now looking at the detail. | Code: | | POOR-USER / # ls -l /boot |
shows no files, except for the grub directory, so your kernel and initramfs are missing from there. Thats maybe no bad thing if they are in /dev/sda6/boot (Ubumtus boot)
| Code: | title=Gentoo Linux-2.6.23-r6
# Partition where the kernel image (or operating system) is located
root (hd0,0)
kernel /boot/kernel-2.6.23-gentoo-r6 root=/dev/sda2 |
The root (hd0,0) here is incorrect as (hd0,0) is the first partition on the first hard drive discovered by the BIOS. Its probably /dev/sda1, which from the comments in your Ubuntu fstab is an ntfs partition, so you won't have any kernels there. There are no kernels in /dev/sda2/boot either.
Your Ubuntu /boot has no Gentoo kernels, so your gentoo kernel appears to be missing. Point the root (hd0,0) statement to the partition where the Gentoo kernel is located.
The statement /boot/kernel-2.6.23-gentoo-r6 must match the pathname to the kernel on the given partition exactly so it looks like you intended to put the gentoo kernel into one of your /boot folders.
Given that Ubuntu was your first install add the following to its menu.lst to boot gentoo.
| Code: | title=gentoo
kernel (hd0,1)/usr/src/linux/arch/i386/boot/bzImage root=/dev/sda2 |
This attempts to boot Gentoo from the kernel build location. It fails if your BIOS cannot read the area of the drive where the kernel is located. It fails if you are not on a 32 bit system - change the i386 to suit your box.
Quick test - press 'e' at the grub splash screen and enter the above on two new lines. Follow the on screen instructions to boot.

Not sure if I followed your instructions exactly, but I get "Error 15" attempting to boot from the entry I added to the table.
incase this helps:

rich4,
Error 15 means file not found. Grub loaded but could not find the file it was looking for.
Your fdisk reflects your /etc/fstab files provided Gentoo is on /dev/sda2 and Ubuntu is on /dev/sda6
My | Code: | title=gentoo
kernel (hd0,1)/usr/src/linux/arch/i386/boot/bzImage root=/dev/sda2 |
works only if you compiled your own kernel. If you used the networkless install and the kernel from the CD, you don't have a kernel at /usr/src/linux/arch/i386/boot/bzImage.
However, your posted | Code: | | /boot/kernel-2.6.23-gentoo-r6 |
which is not the liveCD kernel, it uses kernel-2.6.19-gentoo-r5.
I suspect one of us made a typo in the path name.
Get into your Gentoo chroot and check that | Code: | | /usr/src/linux/arch/i386/boot/bzImage |
exists.
Tab completion is your friend.

bash: cd: /usr/src/linux/arch/i386/boot/bzImage: No such file or directory |
I did compile my kernel manually, and through poking around I was able to get into the kernel recompilation screen. I believe that screen showed the settings which I selected whilst compiling my kernel. Maybe this helps |

rich4,
Your cd would fail as bzImage is a file, not a directory.
| Code: | cd /usr/src/linux/arch/i386/boot
ls -l |
would show it.
After you did | Code: | cd /usr/src/linux
make menuconfig |
to set the kernel options, did you do
| Code: | make
make modules_install
cp arch/i386/boot/bzImage /boot/kernel-2.6.23-gentoo-r6 |
Well, I know you did not do the last step, or it failed for some reason as there is no file /boot/kernel-2.6.23-gentoo-r6 on your system.

It does that on my 3 computers (2 amd64, 1 remaining x86), I must say that it does that on *every* grub updates ever, a link to a binary .tbz2 would be much appreciated (there's no real reason to compile it, and binaries for x86 work on amd64)

cylgalad2,
I think amd64 needs grub-static as grub is known not to build on pure 64 bit systems.

|
|
My old harddrive was filling up so I bought a new one and migrated everything over. I have the new drive attached using a USB/EIDE adaptor for migrating everything over. It is /dev/sda and (hd1).
I essentially copied the partition tables, excepting larger sizes on the new ones:
| Code: | Helios2 ~ # fdisk -l /dev/sda <--NEW DISK
Disk /dev/sda: 250.0 GB, 250059350016 bytes

/dev/hda4 5122 7296 17470687+ 83 Linux |
I created all the filesystems like so:
a1: NTFS (Windows XP)
a2: ext2
a3: swap
a4: ext3 (new) reiserfs (old)
Then I copied over all the data using cp -av for each respective partition (doing the windows one in XP). I used the Windows recovery console to write a windows boot sector to a1 by issuing
then I booted back into linux (on the old drive) and installed grub:
| Code: | grub> root (hd1,1)
Filesystem type is ext2fs, partition type 0x83
grub> setup (hd1)
Checking if "/boot/grub/stage1" exists... yes
Checking if "/boot/grub/stage2" exists... yes
Checking if "/boot/grub/e2fs_stage1_5" exists... yes
Running "embed /boot/grub/e2fs_stage1_5 (hd1)"... 16 sectors are embedded.
succeeded
Running "install /boot/grub/stage1 (hd1) (hd1)1+16 p (hd1,1)/boot/grub/stage2 /boot/grub/menu.ls
t"... succeeded
Done. |
OK, so now everything should be set up the same as it was before but when I shut down, pull the old drive, insert the new one and boot back up I get something like:
| Code: | Loading stage1_5...
GRUB Error 17 |
I thought I copied everything as similarly as possible, but I guess I missed something.
Here are the grub config files:
| Code: | Helios2 ~ # mount /dev/sda2 /mnt/usb

That means (hd0) goes away and (hd1) becomes (hd0).
Grub embeds the (hd1,1) in the MBR at install time, so its looking for the right partition on the wrong drive.
Boot the liveCD, get into the chroot and reinstall grub to the MBR.

Interesting... I would have expected a grub error 21 (disk not found) instead of error 17 in that case. So by chrooting to the new drive, grub looks at it as hd0 instead of hd1 then? I'll give it a try and we'll see how it works.
Thanks!

OK, so I tried it but I'm a little confused...
I did the chroot sequence as described in the Gentoo Handbook http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=1&chap=6
I did a 'touch NEWDISK' on the root and boot partition of the new disk so that I didn't get confused about which drive was which. Once inside the chroot I opened up grub and tried looking for the NEWDISK file on hd0 but it only appears on hd1!
| Code: | grub> find (hd0,1)/
Possible files are: lost+found .keep vmlinuz-2.6.16-gentoo-r9 vmlinuz System.map-2.6.16-gentoo-r

I think I've found another way around it though... how about this?

Done. |
It ran without error, so hopefully when I reboot on the new drive it'll just work! Here goes. |

Well that didn't work too well. When I swapped in the new drive, I got a new error:
GRUB Hard disk error.
Hmm... |

NeddySeagoon,
I want to thank you for this how-to. I used it on this machine, and it seemed to pep the performance of the both the SATA and PATA interfaces. The only departure that I have to make is I have to say "y" to ACHI SATA. Apparently, just choosing the Intel ESB, ICH, PIIX3, PIIX4 PATA/SATA support option wasn't enough. I had to add that one extra driver.
But I cut out the ATA/ATAPI/MFM/RLL support section entirely. It seems to be a good thing. The hard drive was SATA anyway, so it was already sda. No big deal, just reconfigure Gxine and a few other multimedia programs to use /dev/sr0. K3b and k9copy did it automatically...nice.
Which brings me to my Toshiba Laptop. It is all hdx (hda hard drive, hdc DVD ROM). If I don't enable the ATA/ATAPI/MFM/RLL support section, all the drives get renamed...and the kernel panics. In this case, I guess I have to set everything up in fstab, reboot, and run lilo modified for the drive name change afterward. Whatta ya think?
Well, wish me luck, I'm about to find out. It should be interesting!
Blessed be!
Pappy
EDIT: That didn't go so well. Can I change my drive names from hdx to sdx on the Toshiba laptop? Is GRUB a must to make this happen?

Hi@all
I have got a really major problem.
The good news is: I know what I did wrong.
The bad new: I don't know how to fix it  .
I typed a wrong kernel version in the grub.conf.
So I can't boot the normal kernel.
I am able to boot the rescue entry. When I type
| Code: | | nano -w /boot/grub/grub.conf |
it looks like there is no file like that because the editor opens a clear one.
Can I edit the file with knoppix??
What can i do? |

pappy_mcfae,
Neither grub nor lilo know anything about kernel or udev allocated /dev entries during the time the bootloader is in charge of the system.
When you change /etc/lilo.conf and rerun /sbin/lilo, lilo generates an block list of the file(s) it needs to load and writes this to the MBR.
At boot time it blindly reads this block list into memory. This accounts for the unexpected or unpleasent results if you update your kernel and forget about /sbin/lilo ... it still reads whatever is at the old disk location.
If you are unlucky, its a part of a kernel and you have to find your liveCD. If you are 'lucky' its an old but intact kernel. I say 'lucky' because your system starts but the kernel changes you just made are missing, and tracking it down can take a while.
Grub is a little different. During booting, it knows nothing of any /dev/ entries, as they are not created until the kernel is loaded, mounted the root filesystem and started udev. (lilo is the same in this respect).
The grub stage 1 (the 448 bytes max in the MBR) loads the grub stage 1.5 from the sectors following the MBR. stage1.5 can read the filesystem on /boot, which it reads to load the grub stage 2 file. This reads grub.cnf to find out what to do.
When you drop the IDE kernel support from ATA/ATAPI/MFM/RLL support section, boot loader operation is unchanged. For the avoidance of doubt, the boot loader is finished when it jumps to the kernel start location. Grun and lilo do what they always did.
Things change when the kernel gets control. Your root=/dev/hd... needs to change to root=/dev/sd...
You will have real_root=/dev... if you use an initrd, its the real_root you need to change.
In grub, thats all you do. With lilo, rerun /sbin/lilo or the configuration change will not take effect.
As you have already suggested, you need to change /etc/fstab too, or your root will be read only and other filesystems will not be mounted.
You have have /dev/sd.. in place of the /dev/hd...
A twist is that if you used to leave a USB storage device connected, it may still be /dev/sda and your local hard drive will be /dev/sdb, which you were probably not expecting.

Hi all
Im new to the linux world. I tried to install my first linux system with gentoo...
I made the installation by reading the Gentoo Linux x86 Handbook http://www.gentoo.org/doc/en/handbook/handbook-x86.xml
I made everthing that its stated in the handbook and i didnt even changed a thing...
When the system starts booting, i get this error:
| Quote: | *Checking root filesystem ...
fsck.ext3: No such file or directory while trying to open /dev/ROOT /dev/ROOT:
The superblock could not be read or does not describe a correct ex2 filesystem. If the device is valid and it really contains and ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with and alternate superblock:
e2fsck -b 8193 <device>
* Filesystem couldn't be fixes  [ !! ]
Give root password for maintenance
(or type Control-D to continue): |
This is my partition layout. Its the same as the handbook, the only difference is that my disk is bigger:
| Quote: | Disk /dev/hda: 30.0 GB, 30005821440 bytes
240 heads, 63 sectors/track, 3876 cylinders
Units = cylinders of 15120 * 512 = 7741440 bytes
Device Boot Start End Blocks Id System
/dev/hda1 * 1 14 105808+ 83 Linux
/dev/hda2 15 81 506520 82 Linux swap
/dev/hda3 82 3876 28690200 83 Linux |
The fstab is the same as handbook too:
| Quote: | /dev/hda1 /boot ext2 defaults,noatime 1 2
/dev/hda2 none swap sw 0 0
/dev/hda3 / ext3 noatime 0 1
/dev/cdrom /mnt/cdrom auto noauto,user 0 0 |
This is my grub.conf file:
| Quote: | default 0
timeout 30
splashimage=(hd0,0)/boot/grub/splash.xpm.gz
title=Gentoo
root (hd0,0)
kernel /boot/kernel-genkernel-x86-2.6.23-gentoo-r9 root=/dev/ram0 init=/linuxrc ramdisk=8192 real_root=/dev/hda3 udev
initrd /boot/initramfs-genkernel-x86-2.6.23-gentoo-r9 |
Can someone please help me out?
