(can't use lilo due to amd 64 bit arcatecture or something like that its masked as -*)

Kernel Panic -not syncing: VFS: unable to mount root fs on unknown block (3,2)

here is my config

hda2 linux
hda4 swap

timeout 30
title=Gentoo Linux 2.6.9
root (hd0,1)
kernel /boot/kernel-2.6.9-r1 root=/dev/hda2
title=Windows XP
rootnoverify (hd0,0)
chainloader +1

I'm not sure since i use a seperate /boot partition in fedora different from /
but i have an initrd section after kernel.

This is my grub.conf
# grub.conf generated by anaconda
# Note that you do not have to rerun grub after making changes to this file
# NOTICE:  You have a /boot partition.  This means that
#          all kernel and initrd paths are relative to /boot/, eg.
#          root (hd0,6)
#          kernel /vmlinuz-version ro root=/dev/hda8
#          initrd /initrd-version.img
title Fedora Core (2.6.5-1.358)
	root (hd0,6)
	kernel /vmlinuz-2.6.5-1.358 ro root=LABEL=/ quiet
	initrd /initrd-2.6.5-1.358.img
title Windows XP 
	rootnoverify (hd0,0)
	chainloader +1

Have you tried different "root=" options? Sometimes different things read the name of your Hard drives differently. Just one of my hard drives has been read as hda, hdc, hdd, hde, and sda. This isn't the only reason this problem occurs, but it is the simplest.

If you're using udev (or devfs) and it's incorrectly setup, or you don't have a /dev/hda2 (the device file, not the device) this might happen. Not having fs type support for the /root fs compiled into the kernel can cause a panic, but iirc the error message is different.
