Unable to Install Ubuntu 16.4

[Steve]

The error reported did not give me much information.
I am not an expert user but these bug reports are for much earlier systems
Would the problem be solved by deleting windows (which I hoped to keep)
If that would solve it how do I do that as the installer disc dose not give me that option on rerun

You are trying to install in a modern EFI based computer so you need to use the 64 bit version.
