I did that, but before, I would like to understand something.
this system is not scsi at all.
when I booted using the rescue disk, I did a "fdisk -l" and from there, I saw 
the following output :
disk /dev/hda - 40 gigas
and there /dev/hda1, hda2, etc...
and :
Disk /dev/sda 160 gigas
I don't understand this "sda", instead of "hdb".
Once there, I did what you said, but as windows is install on the 160 gigas 
HD, I typed :
grub-install /dev/sda
I've got :
no error reported,
This device map was generated by anaconda.
(fd0) /dev/fd0
(hd0) /dev/hda
(hd1) /dev/sda
I've tried to reboot, and all I get is :
GRUB
and nothing else. the system stays that way with just the word "grub".
i've tried with the boot sequence from the bios to switch the first hd to 
boot, but once again, same message : "GRUB" and nothing else.
I'm totally lost, and don't know what to do, to recover my two operating 
systems.

Help would be greatly appreciated ;-)
Thanks. Francois
