i have a removable floppy drive. when i use grub-install it always seems to probe for it even if i set --no-floppy. so i have to connect my floppy drive to make sure grub installs correctly (maybe a good thing anyway
i have also noticed that there is always a /dev/fd0 even if the floppy is not connected - i was wondering if a udev symlink to for /dev/floppy might help? There doesn't seem to be one created which seems a bit odd.
I personnally use the grub mini-bash-like-console
# grub grub> root (hd0,x) # the /boot partition grub> setup (hd0) # the disk where the MBR sould be altered grub> quit
