Hello Jean,

 JP>     Say, what stage of the insstall should I see this offer of Boot
 JP> Manager ?

It's the last thing that happens once everything else is done.

If you boot the installer in expert mode you can choose between grub and
lilo. At least that's the case with debian, ubuntu may be a bit different
if they have modified the installer.

 Ttyl :-),
