grub-install /dev/VolGroup00/LogVol00
The file /boot/grub/stage1 not read correctly
tried:
cd /boot/grub
cat stage1
output maybe human readable by some humans but not this one.
So far I can still see all the user files so I can backup and
reinstall but that wouldn't teach me anything.
All suggestions/insults/how-to's welcome.

Max,
I looked this up on Red Hat's KBase:
http://www.redhat.com/docs/manuals/enterprise/RHEL-5-manual/en-US/RHEL510/Installation_Guide/s2-rescuemode-boot-reinstall-bootloader.html
Hope this helps,
Jim
Thanks for the link but i had tried that and it didn't work. The
following explains why but I don't see an easy way to do it, i'll do it
the hard way , its the only option left, I need some help on best method
or whether its even possible.
From rescue cd, l let me outline what i see like a terminal :
sh-3.2# chroot /mnt/sysimage
sh-3.2# cd boot
sh-3.2#ls
boot grub (there shouldn't another boot directory should there?Also
no config files, no initrd, no system map,no vmlinuz, will copying
from another f8 be good enough to restore these, i would guess yes but I
am getting hungry so i'll deal with that first, i
should have noticed these missing yesterday but it was late etc....rest
of this probably doesn't matter but for the sake of
thoroughness i'll go through everything anyway)
sh-3.2#cd grub
sh-3.2#ls
device.map ffs_stage1_5 reiserfs_stage1_5 vstafs_stage1_5
device.map.backup iso9660_stage1_5 stage1 xfs_stage1_5
e2fs_stage1_5 jfs_stage1_5 stage2
fat_stage1_5 minix_stage1_5 ufs2_stage1_5
I notice as I type this that menu.lst, menu.lst.backup, and
splash.xpm.gz are all missing, i'm not quite sure how to regenerate
them, I could copy them from my other box but menu.lst won't be
identical.....i'll have to think about that one but without missing
files in boot what does it matter?Missing files would explain why grub
says it can't find stage1, presumably it needs the missing files in
/boot to locate stage1
If you remember I noticed another boot directory inside /boot
sh-3.2#cd /
sh-3.2#cd boot
sh-3.2#ls
boot grub
sh-3.2#cd boot
sh-3.2#ls
grub
sh-3.2#cd grub
sh-3.2#ls
device.map ffs_stage1_5 reiserfs_stage1_5 vstafs_stage1_5
iso9660_stage1_5 stage1 xfs_stage1_5
e2fs_stage1_5 jfs_stage1_5 stage2
fat_stage1_5 minix_stage1_5 ufs2_stage1_5
It is the same as the contents of the other grub directory minus the
device.map.backup. I don't think this directory should exist at all but
it may have been created by my earlier attempts to fix grub. While I
don't think it should be there, i don't think it should cause a problem
because I never told grub to look in /boot/boot/grub , without the
missing files from /boot i think i'm screwed. Will copying these from
another f8 do the trick? I think that is the question of the moment. I
am thinking yes because these boxes are updated to the same point(i've
complied a kernel or two so i think it will work) but how much trouble
will it cause? Well I'm off to dinner. All suggestion, insults, etc
Thanks
Max
