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

[Ilan Tal]

On my laptop I tried UEFI and BIOS. In UEFI it would not give an error -
it would just ignore the usb stick and go directly into the usual
Ubuntu. I take this to mean that in UEFI it is intelligent enough to
know that something is wrong, but rather than giving an error, it just
ignores the usb stick. In BIOS it always gives the "boot error".

Now on this machine I disabled the boot from UEFI and put the usb stick
as the top priority disk. Now, here too it gives the "boot error"
message. With 64 bit even the UEFI works properly.

Could you please try it on your machine and verify that it is indeed a
problem. Otherwise the developers will reach the conclusion that I am
doing something wrong and won't know there is a real problem. If Ubuntu
posts the 32 bit version as a real option, it should work and not give
boot errors. It isn't really fair to say "use the 64 bit version".

At this point the problem needs to reach the confirmed stage - or I need
to know why it doesn't work for me on any machine I have tried to date.

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.
