Grub Problem with chain load

[lsatenstein]

My configuration is with two hard disks.
Disk1 has windows and Ubuntu (50-50) and there is no problem with selection of either XP or Ubuntu 8.10.

Disk2, also 50-50 has Fedora 10 on it using lvm

I can chainload to the second drive, but during the boot of Fedora10, it crashes during the boot because the loader cannot find the /root directory (Fedora uses LVM)

If however, I build the grub.conf file from the disk with Fedora10,
I can chain load to the XP-Ubuntu8.10 disk without problems.

I believe that the GRUB that was modified for 8.10 is not recognizing lvm partitions.

Any suggestions for a grub parameter that would allow me to select the Fedora10 drive.

Another question.

With today's large drives, is there a reason why we need a swap partition? Why not just a swap file?

Yes, you can certainly use a swap file instead of a swap partition, and to my knowledge I don't think there is any special advantage of having a swap partition vs. a swap file. But about your booting problem, in order to get a clearer picture of your setup, how about doing:

cd ~/Desktop && wget 'http://home.comcast.net/~ubuntu_grub/boot_info_script.txt' && sudo bash boot_info_script.txt
That will create a "RESULTS.txt" file in the same directory from where the script is run, namely your desktop; please copy/paste the contents of that file to your next post. That will help clarify your setup and what your problem might be. It would be best to run that script from Ubuntu and not Fedora, because for one thing Fedora does not use sudo as I understand it.

A swap file is fine. But if you use hibernation, it is it little bit more difficult to set up.

I'll bite.
I'm having trouble with grub chain loading as well.
I have gentoo on a second drive (hd1), windows and ubuntu on the main (hd0).
I read <This (http://www.debuntu.org/how-to-booting-another-grub-from-grub)> and it booted windows.
that section of my grub.conf/"menu.lst" looks like this:
title Gentoo Linux 2.6.26-r4
root (hd1,0)
chainloader +1

That will create a "RESULTS.txt" file in the same directory from where the script is run, namely your desktop;
The result was a file called boot_info_script.txt which was an html page saying that personal sites are down. The file is attached.

[caljohnsmith]

Ogredeschnique, I just checked right now and the script is available on the server. How about trying again the commands from post #2 and let us know how it goes.

It looks like you unintentionally posted the contents of the boot_info_script.txt; please post the contents of the "RESULTS.txt" file instead. :)

[ogredeschnique]

Um, whoopsie?
Where is the RESULTS.txt supposed to be created? It seems to be missing from my desktop, as in it wasn't created there.

[caljohnsmith]

OK, how about deleting any boot_info_script.txt files from your desktop, and try running the script again with this command:

cd ~/Desktop && wget 'http://home.comcast.net/~ubuntu_grub/boot_info_script.txt' && sudo bash boot_info_script.txt && gedit RESULTS* &
See if that works and let me know how it goes.

[ogredeschnique]

I really appreciate your help, by the way.

And a "thinking" blinking cursor with no prompt.

Crtl+c yields
[2]+ Stopped cd ~/Desktop && wget 'http://home.comcast.net/~ubuntu_grub/boot_info_script.txt' && sudo bash boot_info_script.txt && gedit RESULTS*
but there doesn't seem to be anything happening.

[caljohnsmith]

Did you give the script at least a minute or two to complete executing? If not, please try again. But if the script hung without completing, how about instead trying:

cd ~/Desktop && wget 'http://home.comcast.net/~ubuntu_grub/boot_info_script21.txt' && sudo bash boot_info_script21.txt && gedit RESULTS* &
Let me know how that goes.

[ranch hand]

Yup, I am lurking. Who knows, I may learn something. "They" say this is good for people over 50.

[ogredeschnique]

It had definitely hung.
Well, I ran the txt file script as root and it gave me a Result.txt

============================= Boot Info Summary: ==============================

=> Grub is installed in the MBR of /dev/sda and looks on the same drive in
partition #4 for its boot files.
=> Grub is installed in the MBR of /dev/sdb and looks on the same drive in

[caljohnsmith]

Ogredeschnique, can you maybe boot your Ubuntu Live CD and run the script from there? The part you posted about what is installed in your drives' MBR is unfortunately not enough to help you with your problem.

Great to see you around; have you had any input interface problems with the bovine devices recently? :)

[ogredeschnique]

The code you posted did execute completely from a liveCD.

=============================== StdErr Messages: ===============================

No errors were reported.

Ok. I see the problem.
The windows entry on the gentoo grub

title Windows XP
rootnoverify (hd1,0)
makeactive
chainloader +1
And my attempt at the chain loader to my gentoo disk

title Gentoo Linux 2.6.26-r4
root (hd1,0)
chainloader +1

are the same from the perspective of the second drive.
I figured out my problem thanks to you. Much appreciation. :D
But the solution is beyond me as to how to fix the discrepancy.

[caljohnsmith]

It looks like you have XP installed to both sda1 and sda3, is that true? If the Windows you want to boot is on sda1, then in your Gentoo menu.lst you could use:

title Windows XP
rootnoverify (hd1,0)
map (hd0) (hd1)
map (hd1) (hd0)
makeactive
chainloader +1

And that should work, assuming you boot the Gentoo drive. Note that it is important to include the mapping lines in order to trick Windows into thinking it is booting off the first boot drive (hd0) and not the second boot drive (hd1) where it really is. If you want to boot Gentoo from your Ubuntu menu.lst, you could do:

title Gentoo Linux
root (hd1,0)
configfile /boot/grub/menu.lst
If you want to instead chainload the Gentoo Grub, you first need to install Grub to its boot sector:

sudo grub
grub> root (hd1,0)
grub> setup (hd1,0)
grub> quit
And then you can use your chainloader entry in the Ubuntu menu.lst:

title Gentoo Linux
root (hd1,0)
chainloader +1
Let me know how that goes or if you run into problems. :)

[ogredeschnique]

I think there might be a bug in grub that causes grub to name the drives differently depending on where grub is installed.
I do have grub installed on the gentoo boot partition. (hd1,0)
but the grub.conf on that partition looks like

title Gentoo Linux 2.6.26-r4
# Partition where the kernel image (or operating system) is located
root (hd0,2)
kernel (hd0,0)/boot/kernel-2.6.26-.gentoo.-r4 root=/dev/hdb3

title Gentoo Linux 2.6.26-r4 (rescue)
# Partition where the kernel image (or operating system) is located
root (hd0,0)
kernel /boot/kernel-2.6.26-gentoo-r4 root=/dev/hdb3 init=/bin/bb

title GenKernel
root (hd0,0)
kernel /boot/kernel-genkernel-x86-2.6.26-gentoo-r4 root=/dev/hdb3 init=/linuxrc ramdisk=8192 real_root=/dev/hdb3
initrd /boot/initramfs-genkernel-x86-2.6.26-gentoo-r4

and it works like that. It's the only way I could get it to boot. Is this a grub bug/feature where grub sees partitions and names them differently according to where it is operating from?
The current entry for gentoo on the ubuntu grub was exactly as you suggested

title Gentoo Linux
root (hd1,0)
chainloader +1
but that boots Windows, and is identical to the grub.conf entry for windows on the gentoo boot partition except for the "title".
Windows is only installed on the first partition of the first drive, just like it likes to be.
When grub is installed on (hd1,0) does it see that as (hd0,0) from the perspective of the second drive?
Because that is what I'm experiencing.

The "working" grub entry on (hd1,0)

title Gentoo Linux 2.6.26-r4
# Partition where the kernel image (or operating system) is located
root (hd0,2)
kernel (hd0,0)/boot/kernel-2.6.26-.gentoo.-r4 root=/dev/hdb3

That /dev/hdb3 would be (hd0,2) in grub terms.


[What if I delete the Windows entry grom the gentoo grub.conf since it is already in the ubuntu menu.lst. Then the chainload would work I think. Also I think that is where you got my second Windows install, the windows grub entry on the gentoo grub.conf. The first being the ubuntu menu.lst. I will try deleting the Wondows entry on the gentoo grub.conf.]

[meierfra.]

causes grub to name the drives differently depending on where grub is installed.

The names depend on the drive you are booting from: During boot up, grub gets its information about the hard drives from the bios. The bios will always report the drive you are booting from as the first hard drive. Grub starts counting at zero, so the boot drive will always be (hd0).


title Gentoo Linux
root (hd1,0)
chainloader +1

but that boots Windows,

That is strange. A possible explanation:

When you boot from the Ubuntu drive, the bios report your drives in the order

/dev/sda (hd0)
/dev/sdc (hd1)
/dev/sdb (hd2)


So (hd1,0) is your only partition on /dev/sdc. It has a Windows XP boot sector. A Windows XP boot sector always looks for the boot files on the drive you are booting from. (that's why you need the map lines for windows) So it looks for the boot files on (hd0,0). This happens to be your windows partitions and you end up booting into Windows.

But I'm not sure about this. Anyway, I suggest to try

title Gentoo Linux 2.6.26-r4
kernel (hd2,0)/boot/kernel-2.6.26-.gentoo.-r4 root=/dev/hdb3



What if I delete the Windows entry grom the gentoo grub.conf since it is already in the ubuntu menu.lst

That will not make any difference.

[ogredeschnique]

Yeah, I finally noticed that my external hard drive was getting in the way. That was my /dev/sdc. I pulled the usb cable for the external out of the computer, and now the chainloader to gentoo the second drive attempts to boot a stage2. Isn't that an attempt to boot the actual OS?

I'm slowly getting my head around this, but what I want is to be able to boot grub on /dev/sdb from /dev/sda*

THis isn't even my thread, so I won't be able to change the title to SOLVED, which will be disappointing to me after all this help.

If you want to boot Grub on sdb from your sda drive, how about setting your BIOS to boot the sda drive, and then add this as an entry in your Ubuntu menu.lst:

title Gentoo HDD
rootnoverify (hd1)
map (hd0) (hd1)
map (hd1) (hd0)
chainloader +1
I believe that should work assuming you only have the two drives connected (with sdc disconnected), but let us know if you run into problems.

[ogredeschnique]

That reloads the main ubuntu grub. Something tells me that it shouldn't.

[caljohnsmith]

That reloads the main ubuntu grub. Something tells me that it shouldn't.
So you are booting the Ubuntu drive, you added that entry from my previous post to your Ubuntu menu.lst, and using it reloads the Ubuntu Grub menu? How about posting the output of the script again so we can get a better idea of what's going on. Is your goal to boot from the Ubuntu sda drive on start up, and just have an entry in Grub to boot the sdb Gentoo drive? If not, please state clearly what you want to accomplish. :)

[ogredeschnique]

This thread is about chainloading. If I wanted something else I'd be in the wrong place. I would like to be able to boot from the sda grub to the sdb grub.

This info will be different as I got rid of some of the confusion and extra partitions that I was preparing. Oh, and that other windows install was a quick boot type OS for playing DVDs. either way it is gone now.

The second partition on sda is sda4. Is that an fstab issue?

## lines between the AUTOMAGIC KERNELS LIST markers will be modified
## by the debian update-grub script except for the default options below

## DO NOT UNCOMMENT THEM, Just edit them to your needs

## ## Start Default Options ##
## default kernel options
## default kernel options for automagic boot options
## If you want special options for specific kernels use kopt_x_y_z
## where x.y.z is kernel version. Minor versions can be omitted.
## e.g. kopt=root=/dev/hda1 ro
## kopt_2_6_8=root=/dev/hdc1 ro
## kopt_2_6_8_2_686=root=/dev/hdc2 ro
# kopt=root=UUID=d8c70ea2-e12c-4ca8-ab81-0e95586769b2 ro

## Setup crashdump menu entries
## e.g. crashdump=1
# crashdump=0

## default grub root device
## e.g. groot=(hd0,0)
# groot=(hd0,3)

## should update-grub create alternative automagic boot options
## e.g. alternative=true
## alternative=false
# alternative=true

## should update-grub lock alternative automagic boot options
## e.g. lockalternative=true
## lockalternative=false
# lockalternative=false

## additional options to use with the default boot option, but not with the
## alternatives
## e.g. defoptions=vga=791 resume=/dev/hda5
# defoptions=quiet splash

## should update-grub lock old automagic boot options
## e.g. lockold=false
## lockold=true
# lockold=false

## Xen hypervisor options to use with the default Xen boot option
# xenhopt=

## Xen Linux kernel options to use with the default Xen boot option
# xenkopt=console=tty0

## altoption boot targets option
## multiple altoptions lines are allowed
## e.g. altoptions=(extra menu suffix) extra boot options
## altoptions=(recovery) single
# altoptions=(recovery mode) single

## controls how many kernels should be put into the menu.lst
## only counts the first occurence of a kernel, not the
## alternative kernel options
## e.g. howmany=all
## howmany=7
# howmany=all

## should update-grub create memtest86 boot option
## e.g. memtest86=true
## memtest86=false
# memtest86=true

## should update-grub adjust the value of the default booted system
## can be true or false
# updatedefaultentry=false

## should update-grub add savedefault to the default options
## can be true or false
# savedefault=false

## ## End Default Options ##

You bios seem to behave like mine. If I use

root (hd1)
map (hd0) (hd1)
map (hd1) (hd0)
chainloader +1

it also still boots from the boot drive.

Try

title Gentoo
root (hd0)
map (hd1) (hd0)
chainloader +1


and

title Gentoo
root (hd1)
map (hd1) (hd0)
chainloader +1

I know that this makes no sense, but both of those work for me.
You can also try rootnoverify in place of root, but that did not make any difference for me.

[ogredeschnique]

Unrecognized device string. both ways.

@meierfra:
I totally understand that you mean about some of this stuff making no sense.
I feel like someone who knew what they were doing #-o could have it working in a flash. I guess that's kind of a joke.

[meierfra.]

Unrecognized device string. both

Sound like a typo. For example there needs to be a space between (hd0) and (hd1) in map (hd0) (hd1)

Also where should be no space between + and 1 in chainloader +1.

Just copy and paste my entries. That should avoid any typos.

[ogredeschnique]

Sound like a typo. For example there needs to be a space between (hd0) and (hd1) in map (hd0) (hd1).
Awesome. That works.
Thank you meiefra.
And thank you caljohnsmith for your patience and perseverance.

The best part is I learned something, with the help of others. Now I'll never have trouble with this exact problem again. :D

[meierfra.]

Glad you got it to work. Chain loading a partition on a different hard drive can be tricky, in particular if on tries to set it up so that the drives stay independent: You can boot into Gentoo not only from the Ubuntu Grub menu, but also by setting your bios to boot from the Gentoo drive. So if your Ubuntu partition gets corrupted you still will be able boot into Gentoo.


Could you do me a favour? There seems to be a small bug in the script.:


Operating System: This is

That line in RESULT.txt really should have said "Gentoo" somewhere.

Next time you boot into Gentoo, could you open a terminal a post the output of


cat /etc/issue

Thanks
