i had installed gentoo thru live cd , i just downloaded the image from the site and performed installation , everything was fine , installation success message came after long 20-25 min.
But one problem i cudnt get my gentoo start , my grub doesnt show any gentoo, actually i have Ubuntu , so GRUB contains windows and ubuntu flavours .

I had edited in /boot/grub/menu.lst like this
title Gentoo Linux 2.6.24-r5
# Partition where the kernel image (or operating system) is located
root (hd0,2)
kernel /boot/kernel-2.6.24-gentoo-r5 root=/dev/sda3

actually i just copied this from gentoo guide , and edited my root to (hd0,2)
i dont knw much about that second root so just left it with root=/dev/sda3
While selecting i get "error 13"

My gentoo is in (hd0,2) and my GRUB in (hd0,4)

So based on my assumption i dont need to copy my kernel image from cd to my location right !! Its already done by the installation , right guys

So plzz help me form this situation!!!!! Looks simpler for u , bizzare for me

I remember I had the same problem a while back, try

kernel /boot/kernel-2.6.24-gentoo-r5 root=/dev/sda5

or

keep kernel /boot/kernel-2.6.24-gentoo-r5 root=/dev/sda3
but change to
root (hd0,4)

it's one of those, good luck.

oops neither didnt work ... Have u installed thru livecd , great man , i have been trying for past one month , i think i need to install it in conventional way ..

I suggest installing the manual way, which is the only supported one. Anyway, you can consider it as an introductory course to Gentoo. If you can't read the handbook and go through it then you are going to have lots of problems to use Gentoo (you won't be able to administer it anyway). Having the will to read the handbook is just part of the process.

About your problem, did you edit the grub.conf in the Gentoo partition? Because if that's so then you did wrong. You need to edit the one in the ubuntu partition, since it's the one that's being used. That is, unless you have a shared independent /boot partition that you use for both Oses.

I'm not able to perform "make menuconfig" after chroot operation ,Is there any way to get menuconfig
For time being i made use of genkernel and executed genkernel all and this shows

so i foud out that it lacks /bin/sh but /bin/bash exist , so i done a weird operation i think so , that is i copied form my Ubuntu machine /bin/sh to /mnt/gentoo/bin , so after that i get this result

ls /bin/sh
/bin/sh

Plz help me i'm stucked , i'm eagerly waiting to get Gentoo installed .
Why these error came , is there any way to get /bin/sh installed after that i need to perform genkernel all operation .
I think one step more to get gentoo installed

You are failing at least on one of the steps.

Did you uncompress the stage3 file correctly? Did you mount the /proc and /dev directories into the gentoo partition? Did you chroot correctly?

Be very careful when doing these steps and be alert for any error. Make sure that you check the integrity of the stage3 file as well with md5sum. A corrupt file will do you no good.

You have to follow the handbook step-by-step, and if one step doesn't work (or you don't understand it) don't continue blindly, come hear and ask for help.

Did you install the proper stage3 file? Are you sure it was correct? The contents of the partition seems to be completely messed up.

Now understood this line of command makes problem for me

zcat /proc/config.gz > /usr/share/genkernel/x86/kernel-config
gzip: /proc/config.gz: No such file or directory

i'm not able to perform , this what all mess started i think .. , i had mounted /proc but not able to view config.gz , thats why i'm not able to perform "genkernel all "

See below in my /proc there is no config.gz , so how will genkernel calls default kernel configuration?

That's very strange. It should be there. But well, I really never tried to use genkernel, in like 6 years of Gentoo I've built my kernels as I always did before.

One thing that you could try is to copy it from the /proc of the cdrom itself, instead of the /proc of the chroot. Assuming that you mounted the gentoo partition in /mnt/gentoo as you said above, the process would be this way:

• run "exit" to exit the chroot
• zcat /proc/config.gz > /mnt/gentoo/usr/share/genkernel/x86/kernel-config
• chroot /mnt/gentoo/ /bin/bash
• env-update && source /etc/profile
  # you are on the chroot again

Maybe there's a valid config.gz there. I have no idea why it doesn't appear on the chroot though. If it doesn't appear there I guess that you will need to pick it from elsewhere.

Yea one day i'll also compile kernel myself like u buddy , but before i need to learn that why looked for better linux
But i didnt understand one thing what to copy from cdrom , i dont have anything like that in my cd drive , or r u mentioning something else?

Sorry, from where are you installing? Are you booting from another distro that's already installed or from the gentoo livecd? I mean, before you chroot you have to boot another linux.

I'm doing this from my Ubuntu 8.10 , so any problem , but i come to know that gentoo can be installed from any distro , right ? Any problem while doing so ?
Can u specify actually where the kernel configuration stored in Ubuntu , coz i think that might be the problem , zcat i think didnt worked coz of that ?

Sorry for the delay, even I have to sleep sometimes

No problem. Maybe ubuntu kernels doesn't have the option to export the config in /proc/config.gz. Can you look into the /boot directory of your ubuntu installation? Maybe the config files are also stored there. Another common place could be /etc/kernels/ or something similar. Check these locations and see if you can find any *config* file around. If not then I will try to pick a generic config file form a gentoo cd or something for you.

Its ok , now everything worked fine .. But still making problem .. This Gentoo is really a hard nut

What i'm now performing is "make menuconfig" options , and i selected whatever options which i feel suitable and make && make module_install everything worked fine , i think so , but whenever i select an option i couldnt figure whether that particular option was selected or not , leave it for a moment , but performed make && make module_install
And i've performed everything step by step from handbook
Now the problem is GRUB
I had emerged GRUB , but i thought why shud i edit gentoo grub , i've my Ubuntu GRUB and i edited that file

title Gentoo Linux 2.6.28
# Partition where the kernel image (or operating system) is located
root (hd0,2)
kernel /boot/gentoo-2.6.28 root=/dev/sda3

/boot/gentoo-2.6.28 that i copied image , OK . and root(hd0,2) where i made my GENTOO , root i just copied from handbook , coz i dont knw much abt that

Still not working .........!!!!!!!!!!!!!!!!!!
