I've just installed linux gentoo following the instructions in the handbook, I've used genkernel to compile my kernel and at some point(while compiling) I got an error saying that the modules have failed to compiled.
I used grub as a bootloader, when i select gentoo I get the following screen:

I'm new to Gentoo so please bear with me
thanks

blakdeath,

Chroot to the gentoo installation from the live media, compile the kernel and paste back the error message you encounter.

Flashing capslock and numlock look almost like a failure in the hardware/bios.

Anyway, the thing to do is to go step-by-step through the Gentoo installation
instructions; when a step doesn't work, post the action and the result here.

blakdeath,

First mount your gentoo partition(s) - if you followed the handbook they should be /mnt/gentoo /mnt/gentoo/boot /mnt/gentoo/home.

Code:
cp -L /etc/resolv.conf /mnt/gentoo/etc/
mount -t proc none /mnt/gentoo/proc
mount --rbind /sys /mnt/gentoo/sys
mount --rbind /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) #\[\e[0m\] "

At this point you should be able to cd to /usr/src/linux and compile the kernel or if you used genkernel you can run that.

well the only failing step I've step was when i got a message saying failed to load modules, maybe that's what caused the flashing and such?
i used genkernel to compile my kernel

Did you add any modules to /etc/conf.d/modules :?:

If needed modules are not being loaded, that's not good :(

Check /usr/src/linux/arch/x86_64/boot/bzImage time stamp against the kernel in /boot. genkernel should take care of copying it, but it would be wise to verify. If modules don't match the kernel they won't load :wink:

I haven't loaded any modules manually, i Just let genkernel do the work, i think this is the reason this entire problem is happening coz of some missing modules
i do not have a /usr directory

No /usr directory 8O

I suspect that you're not chrooting properly or you fumbled somewhere during the setup. After you chroot, what does ls /usr show?

include, lib, lib32, lib64, libexec, livecd, local, portage, sbin, share, src, tmp, x86_64-pc-linux-gnu
that is when i boot from the live cd, if ur referring to the /usr on the root file system
I can't even reach that directory, but windows indicates there are the following directories:
src bin include share lib32 x86_640pc-linux-gnu libexec sbin lib64 local portage

And i Can't list the files
I have no idea what I'm doing nor what I had done
Id start a new installation but Im prettty sure Ill do the exact same

blakdeath,

The flashing keyboard LEDS indicate a kernel "Painic". A kernel panic is a condition that the kernel cannot recover from. In your case, a failure to mount the root filesystem.
Your Panic message is very informative
Code:
unknown-block (0,0)
This tells that kernel cannot communicate with your hard drive at all, never mind read what it finds there.

Genkernel is ok when it works - when it doesn't, give it up and make your kernel manually. You will need to get back into the chroot to do this ... thats already been described.
You will get quite good at this procedure :)

Follow kernel-seeds.org for making and installing your kernel. Its not the put "hairs on your chest" totally manual way, nor the scripted build everything and hope it works way.
Pappys seeds provide a lean mean hardwareless .config file for you to add required hardware options to. How to do this, how to build and install your kernel is described on the website.

For help from kernel-seeds supporters, post in Pappys kernel-seeds sticky thread in Unsupported Software.

Well The matter is I just knew what a kernel was 3 days ago :D
I don't mind learning all this no matter how long it takes, I just dont like to risk my time on something that might not work
Thanks Alot for being patient with me billwho, thank you Neddy But I think Ill be giving up gentoo until I get my next laptop.
Cheers

blakdeath,

You can dual boot with Gentoo while you learn or you can run Virtualbox in $OTHEROS and run Gentoo in that.
Virtualbox is one of the virtualisation software solutions - there are others. It shows its guest operating systems a whole new virtual PC, from the BIOS on up.
Its fast as its not a software emulator. The guest runs directly on the host CPU ... well almost. Its free both as in beer and source code.

The regulars on the forums are quite prepared to help you to help yourself. Few will will feed you but we will teach you to fish.

Yeah I love virtual box, waaaaaaaaaaaaaaaay better than vmware
I can start working on it, but the thing is I have setup several distros in 10 minutes on virtual box that have taken me over 2 hours as a native installation
but its definitely gonna be educational
ill start working on it :D
thanks :D
