The problem is with removable drives. May of todays systems will boot from
the external drive by default because they have no floppy or cd/dvd drive.
So in my case even with the external drive plugged in it failed to reboot
because the BIOS was looking for a bootable external drive. The only way I
could reboot was to tell the bios to select the internal drive even though
the external drive was plugged in, but that was only good for one boot. I
had to reset the bios at every boot. So in the case of a USB drive Grub
has to go on the external drive to boot correctly at all with a netbook
for example. (both of the ones I have here Acer and HP show the same
thing)
