I'm by ways not a grub expert  :-)

I don't know because I never tried it yet and prefer to use the rescue
mode. The way you describe the problem it may be a grub bug.

The Red Hat rescue mode used to scan the harddisk(s) and to present a
list of linux systems it found. You can choose which one to deal with. I
have three different Linux distros installed here (and there is a
Windows and an OS/2 partition as well) and never had any problems with
the rescue mode.
