Still Learning, Grub Still Not Booting -Error 15

[mikel]

Hello,

I have posted previously about this but haven't been able to fix it so far.

I have installed using stage 3 + GRP and using genkernel. Grub boot screen comes up but booting gives an Error 15.

The relevant line in the grub.conf file are:

root (hd0,0)
kernel (hd0,0)/kernel-2.4.20-gentoo-r6 root=/dev/hda3
initrd (hd0,0)/initrd-2.4.20-gentoo-r6


I have tried the suggestion of adding /boot but this has no effect. (As I understand from other posts, (hd0,0) is the boot so /boot is redundant. In this case the installation guide is inaccurate because it says to use exactly the string that genkernel outputs at the end, and that string includes /boot).

I have also tried the suggestion of separating root=/dev/hda3 with a tab from the kernel line but again no change in behavior.

I have looked in my /boot and found the kernel and initrd strings as written.

Now, the strange thing is when I go to the Grub command line from the grub boot screen, if I do the following:

grub > kernel /kernel-2.4.20-gentoo-r6 root=/dev/hda3
grub > initrd /initrd-2.4.20-gentoo-r6
grub > boot

Then gentoo boots! These are the same kernel and initrd strings as in the grub.conf and yet there it won't boot.

Any explanations? What more information can I provide for
diagnosis?

(I tried leaving out the "(hd0,0)" in the grub.conf lines since it doesn't seem necessary on the command line. No joy.)
