To anybody on this list not already familiar with EFI or
{Trusted,Secure} Boot, you may wish to read up on EFI if you'll
configure a new consumer x86 system. I reference a few links I've
vetted, below in case you don't know where to start. I've kept you CCed
for that.

Having a bit of a brain teaser at the moment.
I have been running Ubuntu 12.04 on all my machines but out of
curiosity I tried putting 13.10 on my Thinkpad X120e,
I run a rolling-release distro and would be fine with 13.10. You may or
may not wish to wait four months for the LTS release, 14.04.
it has a 250gig SDD which ran 12.04 just fine.
Likely just generic AHCI. I doubt you'll have driver problems.
I looked at the partitions and saw it had an efi boot partition before
I tried the 13.10 from a thumb drive.
Please look at the earlier thread that R. P. Day started.

I went through the standard install procedure
Which likely won't won't work unless Ubuntu automagically installs
itself differently depending on whether it was EFI or BIOS-booted, and
whether or not the target system is EFI or BIOS.
I wouldn't depend on automagical, only on something that would
explicitly ask me. Anyhow, installing something on EFI manually on a
more transparent distro isn't that hard. I've done it before on
something EFIish (Macbook Pro 6,2, and 10,1—Yes, I *used* to be a Mac
noob). In spite of all the bloat Ubuntu has on top, I wouldn't imagine
it being that hard to swap out the boot loader, etc.
You really should get a whole background on EFI before attempting to
install. I'll quote something I sent R. P. Day but not the list:

I boot using efistub, with rEFInd passing the arguments to the image.

Do you also have ‘secure boot’ in there?

You may need to work around that too.
Once that's all done, you may want to change the default boot option by
setting a few EFI variables, which are stored in NVRAM.

The Ubuntu installer?
that meant starting all over so I did.
I doubt Ubuntu had anything in there that depended on hard-coded
partition layout. Couldn't you have just tarred the filesystem,
repartitioned, and untarred?
to cut a long story short after three attempts I decided to use the
latest gparted IOS and partition before installing so as to make sure
the efi was correctly placed.
Unless you have very odd firmware, I'm not sure how EFI depends on
partition placement. If I recall correctly, it depends on label and/or
partition code.
So whats happening is on reboot after installing the hard drive cannot
be found whichever way I installed.
Really? Or the appropriate *boot option* cannot be found?
I did go into the BIOS
I thought this was EFI? If you colloquially mean ‘some configuration
menu offered by the firmware before handing off boot to something on
secondary storage’, fine.
and make sure UEFI was enabled in both USB and SATA locations,
You have to explicitly enable EFI booting instead of CSM per-medium? It
won't just scan for EFI partitions or give you the option to try to
CSM-boot?
also I tried a DVD install
What do you mean? That you plugged in a portable DVD drive?
as person on a Ubuntu forum in the UK suggested that would work,
Your troubles should be agnostic from the installation medium.
the laptop is from Oct 2012 and the SDD is less
than 6 months old so all hardware is current.
I don't think that this is a hardware problem at all. It's more likely a
firmware issue, or just a misunderstanding about EFI.
I hope I have provided enough information for someone to perhaps make a
suggestion or two.
Call?
13.10 works fine on this machine installed on a spinning disc
Do you mean that CSM-booting the stock live Ubuntu DVD works?
