I was about to say that you couldn't have been accidentally opting for wubi, BUT, I just took a look inside my own 12.10 iso and saw that wubi.exe is included there.
Let me clarify, I don't have windows on any machine at home (haven't had since 2002) so I had no idea that wubi.exe was on the regular install iso as well.
I guess what happened is that after you burned the iso to DVD wubi.exe autoran and that's where you got the dialogue boxes you initially referred to.
Whether you use the 12.10-i386 or the 12.04-i386 (that you're now downloading) I am now 99% certain your problem is the boot order of your devices in your BIOS which is why on reboot you went straight back into windows namely because the HDD is the first selected device
Switch the order to boot from CD first and you should see the Ubuntu installer load up
I have left Windows on (just partitioned the hard drive) for now until I get used to the Linux system.
Thank you everyone for your help!
Congratulations - have fun
