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

[Luigi R.]

This is the output of the script concerning Ubuntu 13.10 installed on
the USB 3.0 as classical installation.

What look strange to me is that grub is not located at the first sector
of the /sdb device. Is that normal?

 Why is not possible anymore to install the /boot partition in fat32?

Thanks

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:
