<p>Rob is correct - recent Ubuntu ISO images should be directly
bootable when dded to a USB flash drive. This has been the case
since at least 16.04, probably earlier, for at least amd64 images
(I'd presume i386 images, too, but amd64 are the only ones I use,
so I can't vouch for them personally).</p>
<p>Geoffrey, if you open a terminal and run "sudo apt-get update
&& sudo apt-get dist-upgrade -s", what is the output?</p>

<pre wrap="">An iso file is actually a DVD/CD image rather than a disk image and so
can't be directly written to a disk via dd.
Instead use something like 'usb-creator' to take the iso image and put it
on the disk in the right layout etc.

<pre wrap="">Recently I have downloaded Linus iso images and loaded them to storage
disks. The first was lubuntu to a TF card to be used with an OrangePi One
and the second, this week, ubuntu 17.04 to one of my desktop PC's HDDs. I
used the standard terminal command for this loading procedure. For example,
with the iso on the desktop the terminal command was: sudo dd bs=4M
if=~/Desktop/ubuntu-17.04-desktop-i386.iso of=/dev/sdb1
My PC confirmed that the operating systems were properly installed on
their respective storage media but neither would boot. For 17.04 my PC gave
a reason for not booting, viz. "isolinux.bin is missing', which is not true
as the file is in the iso. My question is: Have I left something out in the
installing procedure? Or any other suggestions.
By the way, my reason for obtaining the 17.04 image was to replace
16.04LTS which has developed a fault - both the Updating and Ubuntu
Software apps have stopped working (a first time event for me). This
leaves me in a 'Catch 22' situation. As the 17.04 iso image won't boot I
have ordered a 32-bit disk from Peter Baker using the on-line source
ubuntu.net.au.
