Title:
  Ubuntu 13.10 does not boot from USB stick 3.0

Status in “grub2” package in Ubuntu:
  Incomplete

Bug description:
  I have tried to perform a normal installation of ubuntu 13.10 on a
  usb3.0 stick sandisk 16Gb, formatted ext4.

  I do not how to provide you more information since grub does not even
  start and a violet screen hangs. I was suspecting a corruption of the
  usb mbr and I have tried updating directly the grub the I have on the
  hard disk used by ubuntu 13.04 and windows 7 with the key plugged in
  but again just violet screen and everything hangs.

  If I create a live usb in fat32 I do not have any problem. Could you
  please verify if there is a bug in ext4?

  Before on the same usb I had Ubuntu 13.04 but in UEFI mode since I was
  using a netbook UEFI. Now for sure I have a bios legacy and for this
  reason I have removed everything to reinstall ubuntu 13.10 in the mbr.

  The usb key has been formatted in gparted recreating again the
  partition table in msdos as follow:

  Le voci nella tabella delle partizioni non sono nello stesso ordine
  del disco.

  Disk /dev/sdb: 15.5 GB, 15504900096 bytes
