After trying and failing many times to create a bootable USB, I finally managed to create one using Universal USB Installer from PenDriveLinux.com. I created a bootable USB with Ubuntu 13.10 64-bit flavour and managed to successfully boot to the USB after disabling Secure Boot, enabling UEFI & Legacy boot and manually selecting my USB drive.
After successfully installing Ubuntu on a new partition on my SSD, I removed my USB stick, restarted my computer and spammed the Enter key in order to get into my BIOS. I went to manually select where to boot from, but there was no new option for Ubuntu.
Because I'm a computer science student, I think of myself as being fairly clever and so I simply selected my SSD, but it ran through a different boot sequence (neither what my computer used to boot through nor my new shiny Ubuntu OS). What I think is happening is that my computer normally quick boots Windows 8.1 through my 16GB mSATA, but it booted Windows 8.1 through my SSD when I selected it, rather than Ubuntu.
So what I'm asking is, how do I get it to boot Ubuntu rather than Windows 8.1 from my SSD when both are located on the SSD and there is no option for anything else? Is there a way to modify the BIOS so that it gives me the option to boot from one partition on my SSD rather than another? I have as of yet been unable to boot into Ubuntu, I've only managed to boot to Windows 8.1 two different ways.
I've included tech specs below, but if you need any more information I'll make sure to follow up.
