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

[Ilan Tal]

Hi Phillip,
You are mixing apples and oranges. Let me clarify. With the virtual machine I use the iso file directly - no problem there.

It is the boot from power off using a boot from a usb disk on key, where
there is a problem. In that case it passes the BIOS and tries to boot. I
just did it on my laptop and I can hand copy what is on the screen:

SYSLINUX 6.03 EDD 20150813 Copyright (C) 1194-2014 H. Peter Anvin et al
Boot error

I am not yet in any operating system, other than the BIOS which I just
passed. What I expect to happen, if all would work, is that it go into a
screen asking if I want to try Ubuntu or install Ubuntu.

BTW a friend has a machine with 2GB with no CD and the only way I can
convert it to Ubuntu is with a disk on key, so it is fairly urgent. Also
it isn't a great idea that the official Ubuntu software (32 bit) doesn't
boot from a disk on key. The 64 bit version boots with no problem.

The second part of your question is irrelevant. No CD and no USB for
making the virtual machine. The virtual machine came directly from the
iso file - with no problems. I did this as a further check that the iso
itself is OK. Just the boot when you do it from a power down state via
usb, is there a real problem.

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.
