Title:
  mac mini shows usb disk only as fd0

Status in grub2 package in Ubuntu:
  Expired

Bug description:
  Binary package hint: grub2

  I start my efi-gpt mac mini system using refit.sf.net. I wanted to boot an extern usb-stick using grub2 on there. I had done:
  grub-install --recheck --no-floppy --root-directory=/mnt /dev/sdb1

  This disk showed up in refit, but it ever failed to boot from there, falling back to my /dev/sda3 ubuntu grub2 without notice.
  I had a look in /dev/sda3 ubuntu grub2. It showed all (hd0,x) partitions and one entry was:
  "grub> ls"
  (fd0)
  without any (fd0,1). Trying to "set root=(fd0)"  in /mnt/boot/grub/grub.cfg did not succeed. Perhaps I'll try later setting a device.map and without --no-floppy: grub-install --root-directory=/mnt --recheck /dev/sdb1

  Browsing through the source
  http://refit.svn.sourceforge.net/viewvc/refit/ I got the impression
  there is work underway to utilize some apple firmware bits to get
  around this well known bug of not getting a second harddisk to boot
  through refit....
