Booting sparkly new F12 install, error 13 from grub.



Greets;

Resend as there has been no reply, with added info.

I finally said to hell with it and let F12 install itself on /dev/sdb
with all its defaults.

I was surprised on the reboot when my usual grub menu from
/dev/sda was all that showed up, no mention of an F12 install at all.

Added: I had it install everything in the options list, but gave it only 
/dev/sdb to play with in the available disks menu's, & use the defaults on 
/dev/sdb, so it made a  100 meg /boot, using ext4, and a logical volume out 
of the rest of the drive.  I have NDI how to query the filesystem used there, 
other than trying to mount /dev/sdb1 as ext3 fails.

So, since I had blown away a centos install to put F12 on /dev/sdb, I
carved up a fresh grub stanza that reads like this and added it to
/dev/sda1/grub/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 (hd0,0)
#          kernel /vmlinuz-version ro root=/dev/sdb3
#          initrd /initrd-version.img
#boot=/dev/sda
default=19
fallback=1
timeout=15
splashimage=(hd0,0)/grub/splash.xpm.gz

[...]

#21 new stanza
title	Fedora 12 (2.6.31.6-162.fc12.x86_64 from dev/sdb)
	root (hd1,0)
	kernel /vmlinuz-2.6.31.6-162.fc12.x86_64 ro root=/dev/mapper/vg_coyote-
lv_root  LANG=en_US.UTF-8 SYSFONT=latarcyrheb-sun16 KEYBOARDTYPE=pc 
KEYTABLE=us rhgb quiet
	initrd /initramfs-2.6.31.6-162.fc12.x86_64.img

which is in fact pasted from the /dev/sdb1/grub/grub.conf except for the
initial "root (hd1,0)" statement.

So it looks as if I might have to 'chainloader +1 ' it instead, so how
do I do that?  I've never done that before.

Also, that /dev/sdb1 partition only mounts as ext4 if that is important.

Added: I experimentally added a 'chainloader+1' as the next line after the
root (hd1,0) in the /dev/sda1/grub/grub.conf, but all that seemed to do was 
add another 10 second delay before I get the error 13 message.  I would have 
thought from what little I know about grub, that this should force a reload, 
effectively a grub restart, from the mbr of /dev/sdb.  Is there something I 
need to change in the /dev/sdb1/grub/grub.conf also?

Thanks.
