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

[Ilan Tal]

Public bug reported:

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.
