Preseeding and GRUB problem

[Alain <alain.listes@free.fr>]

Hi all,

I'm new on this list, but I didn't see any problem like mine in the 
mailing list archive.
I'm trying to build my own Debian Etch CD-ROM, customized with a preseed 
file.
The customization consist of adding some Debian packages and install 
them without any question.
All seems to work right, but when the machine reboots, it stops with the 
grub prompt.
It seems that no kernel was found. However, the installation process 
reports no error.
I've tried to build another CD without preseeding, just by adding the 
wanted packages in the /pool directory, I obtain the same result.
So I think I made a BIG mistake somewhere, but I can't find where.
Does someone have an idea ?

Thanks,

Alain
