gentoo installation will not boot
If I'm understanding the problem correctly, it sounds to me like the grub problem you described may be at the root of the issue. You shouldn't have to be chrooted to the /boot partition, but instead you should be chrooted to /mnt/gentoo (or wherever your "new" partition gets mounted to). You will need to boot into the livecd again to fix it.
Boot to livecd
mount /dev/<hd wherever your root partition is> /mnt/gentoo
mount /dev/<hd wherever your boot partition is> /mnt/gentoo/boot
mount -t proc none /mnt/gentoo/proc
mount -o bind /dev /mnt/gentoo/dev
chroot /mnt/gentoo /bin/bash
export PS1="(chroot) $PS1"
Now you will be chrooted to your computer's filesystem.
Now check your boot partition.
you should see something like this:
boot grub kernel-2.6.22-gentoo-r8 lost+found
If grub is there, then grub is installed and configured. If it isn't, just reconfigure grub. If you don't have any sort of kernel image in your boot partition then you will also have to do the following:
ls -l /usr/src/
you should see something like:
lrwxrwxrwx 1 root root 22 Oct 2 2007 linux -> linux-2.6.22-gentoo-r8
drwxr-xr-x 20 root root 4096 May 11 14:12 linux-2.6.22-gentoo-r8
drwxr-xr-x 19 root root 4096 Nov 13 2007 linux-2.6.22-gentoo-r9
The arrow on the top one (linux) should point to the currently used kernel which you configured in genkernel. If it doesn't then you may have made a mistake when configuring your kernel. (As an additional note, I know that a lot of people use genkernel, but I tend to tell people to just do it manually. It is slightly more difficult, but then you always can trace back to what you may have messed up on.)
cp arch/i386/boot/bzImage /boot/kernel-2.6.24-gentoo-r5
(or whatever kernel version you have)
Now check /boot/grub/grub.conf to make sure that you are pointing to your newly minted kernel image.
Everything should be good from here on out. If you get any further grub errors, then you may need to get back on the livecd, chroot into your system and just run the setup in grub.
Good luck, hope this helps. (I hope I didn't miss a step)Linux since: 2001

I fix things until they break.
Not sure if you managed to get round this or not. One other thing that i found when instaling Gentoo on my latest machine (Now using SATA not IDE) was that genkernel messed that up (this was a few months back, so may have been fixed now). I just could NOT get gentoo to boot using a genkernel built kernel.
My fix was fairly simple - though to those not in the know doesn't sound it - build my own kernel manually.
Now this may sound daunting, but if you have mounted proc onto the chrroted system, you can simplyCode:
zcat /proc/config.gz > /usr/src/linux/.config
I know this is not an ideal solution, but i think that the generic kernel on the gentoo livecd has made a good job of it, not including rubbish. Though you may wanna just check through the config for things that you *KNOW* you do not need, and also check the filesystems that (at least /boot's filesystem) is compiled *IN TO* the kernel, and NOT as a module."I am not an alcoholic, alcoholics go to meetings"

I found problems with genkernel ... if you don't set valid entries in fstab before running genkernel then it gets a bit confused because it uses fstab to determine mounts. I reported it as a bug but got the finger ... if you try the install process and set valid fstab entries you may find things work ... they did for me
