[gentoo-user] Grub problem. Gentoo doesn't boot. VFS Cannot start...

[Isern Palaus Montasell]

Hello all,

This is the first time I install Gentoo Linux. This is my grub.conf file:

> default 0
> timeout 10
> splashimage=(hd0,2)/boot/grub/splash.xpm.gz
>
> title=Gentoo Linux 2.6.18-r2
> root (hd0,2)
> kernel /boot/kernel-2.6.18-gentoo-r2 root=/dev/hda4

> title=Gentoo Linux 2.6.18 (Rescate)
> root (hd0,2)
> kernel /boot/kernel-2.6.18-gentoo-r2 root=/dev/hda4 init=/bin/bb
> boot

> #Windows XP Profesional
> title=Windows XP Profesional
> rootnoverify (hd0,0)
> chainloader +1


Windows XP boots well but Gentoo Linux no. Start booting but prints this:

> [...]

> Kernel panic - not syncing: VFS: Unable to mount root fs or

I don't know where is the problem, here is my /etc/fstab file configuration:

/dev/hda1 is a Windows Partition
/dev/hda3 is a Linux Partition for boot
/dev/hda4 is a Linux Partition for root
/dev/hda4 is a Linux Partition for swap.

Thanks in advance and sorry for my school English.
