I am a Linux Newbee, running ubuntu 12.04 i386 on a 64-bit machine.

Now I just downloaded Ubuntu 12.10 AMD64 iso and made a bootable USB using Startup Disk Creator. I was directed to install available updated packages, which I did install. The Startup Disk was succesfully created.

But when I tried to boot from the USB I am getting a BootError message and nothing else.

What could have gone wrong?

The Issue in the above scenario was with USB Emulation in BIOS. After i switched the USB Emulation to 'Fixed Media', the installation was flawless.

It's not clear what you're trying to do. But if you would like to upgrade from 12.04 to 12.10 you can do this more easily, efficiently and safely by means of a system upgrade from within your currently running Ubuntu 12.04. If you weren't prompted for this you may need to start "Software Sources", go to the "Updates" tab and change the option for "Notify me of a new Ubuntu version:" to "For any new version".

If you would like to create a live USB disk using Ubuntu 12.10 iso file you've downloaded, I recommend installing and using the MultiSystem utility available from here: http://liveusb.info/
