[Bug 1245147] Re: Ubuntu 13.10 does not boot from USB stick 3.0

[Luigi R.]

Could be a too long UUID? The Ubuntu is installed on the key under
/dev/sbd1. Does it make a difference if ubuntu is installed on primary
or logical partition? On the hard disk ubuntu is in a logical partition
(sda7)

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:

  del disco.
