/boot/grub2 exists.

I made an F16 livecd. edited /boot/grub/grub.conf:

default=0
timeout=2
title 3.2.2
kernel /vmlinuz-3.2.2-1.fc16.x86_64
root=UUID=017cd53d-21ae-43b5-b8ce-b23b15092273 ro rd.md=0 rd.lvm=0
rd.dm=0 KEYTABLE=us quiet SYSFONT=latarcyrheb-sun16 rhgb rd.luks=0
LANG=en_US.UTF-8
initrd /initramfs-3.2.2-1.fc16.x86_64.img

all taken from grub2/grub.cfg.

It booted, but then died with a dracut prompt - and I had no clue what
to do then.

Running grub2-install from the livecd doesn't work. Ubuntu seems to have
a tool "boot-repair" on their livecd, but I can't find anything like
that on Fedora.

So,

How do I boot the using grub - so I can run grub2-install natively?

OR how do I install grub2 from the livecd - or otherwise?

Used the ubuntu boot-repair program. That installed the grub2 bootloader. Didn't go any further with the ubuntu tool since I wasn't sure how it fit with fedora.

But now how do I get up the grub2/grub prompt described in the wiki??
