Hi Goh,
Read the reply from Jordan and my reply to that!
It seems the "root=LABEL=2010_1_64_root ro" is redundant!
This works fine :-

menuentry 'Mandriva 2010.1 x86-64 root' {
search --no-floppy --label --set 2010_1_64_root
linux /boot/vmlinuz
initrd /boot/initrd.img
}

I have found that grub.cfg is *very* fussy about syntax and just blows 
up without error messages if anything is wrong, probably because it is 
not intended to be edited by humans!
I spent a whole night with similar problems trying to figure why entries 
were missing - I thought that I was editing a different file maybe in 
the mount point with the partition not mounted - I was pulling my hair 
out! Turned out to be a missing ' on one occasion and a missing trailing 
brace another time!
I think grub2 also does some checking of paths in menu entries, and 
ignores the menu item if a path fails. I would prefer an error message :-(

Cheers - Barry
