[gentoo-user] system can not find kernel, "hda3" or unknown block (0,0)

[Joseph]

I'm trying to figure it out what happened during my process of switching to 
systemd and I'm lost
When I try to boot I get:

"hda3" or unknown block (0,0)

In grub.conf I have:
root (hd0,0)
kernel /kernel-current root=/dev/hda3
