[Bug 1512811] Re: 15.10 32 bit download gives error when run from usb

[Ilan Tal]

I just did another experiment. There is something illogical about using this machine with 12GB to make a 32 bit stick, so I tried using Startup disk creator on a laptop with 32 bit Ubuntu. This one I updated using a DVD with 15.10 32 bit. Exactly the same problem comes up: from a power off a boot from the physical usb stick gives a boot error.
So it isn't this particular machine has a problem making the stick. Even a machine with 2GB and a 32 bit system has the same problem. I am very surprised that you can't duplicate it on your machine.

Now I will try dd, which I have never used. We need to nail down if the
problem is in the iso or in the program which writes it to the stick.

Title:
  15.10 32 bit download gives error when run from usb

Status in grub2 package in Ubuntu:
  Incomplete

Bug description:
  There seems to be a problem with the grub when trying to use 15.10, 32 bit downloaded from the official Ubuntu site.
  The 64 bit version works fine.
  If I take ubuntu-15.10-desktop-i386.iso and use it to define a new virtual machine in virtual box, again all works well.
  Only if I use Startup disk creator to burn it to a usb disk on key there is a problem.
  Instead of Try Ubuntu coming up I immediately get a boot error.

  I tried downloading a second version of the iso and the problem
  repeated. Also if I download xubuntu-15.10-desktop-i386.iso the
  problem also appears.
