After installing Gentoo(inside VirtualBox), I get this when I try to boot ...
Code:

>>Booting (initramfs)..
INIT: version 2.88 booting
_


I used genkernel:
Code:

initramfs-genkernel-x86-3.10.7-gentoo
kernel-genkernel-x86-3.10.7-gentoo


Here are my partitions:
Code:

/dev/sda1 boot
/dev/sda2 swap
/dev/sda3 /


Here is my grub.conf
Code:

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

title Gentoo LInux 3.10.7
root (hd0,0)
kernel /boot/kernel-genkernel-x86-3.10.7-gentoo real_root=/dev/sda3
initrd /boot/initramfs-genkernel-x86-3.10.7-gentoo

#vim:ft=conf:

What happens without initramfs?
What did you set as default console during kernel build?

What about root=/dev/sda3 instead of real_root=/dev/sda3, will it boot that way at least?

Guessing a broken initramfs at this point but ... not sure...

If initramfs is broken, how do I fix it?

In your kernel and initrd lines in your grub.conf file remove the "/boot" part of it.

You already have grub looking at the /boot partition with your root statement, so if there isn't a symlink in /boot that leads to /boot then the actual path that you are searching is /boot/boot/blah.

Does that make sense?

What happens if you change your grub.conf as follows:

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

title Gentoo LInux 3.10.7
root (hd0,0)
kernel kernel-genkernel-x86-3.10.7-gentoo root=/dev/sda3
initrd initramfs-genkernel-x86-3.10.7-gentoo

#vim:ft=conf:

What we're trying to do is completely remove initramfs from your setup as you may not really need it just to simplify things a bit. Comment out or remove the initramfs line and see what it does.

put a slash at the beginning of the kernel and initramfs lines (if you are keeping the initram line that is) The slash makes it an absolute path.

[edit] kernel /genkernel-line is what I meant, btw. :D

Well I decided to install it natively. Instead of installing
Grub from Gentoo, I used Arch's. I'm dual booting Arch
and Gentoo.
I know I should have done that earlier, but I wanted
to try and fix the problem first.
