I am trying to install Ubuntu 12.10. I have downloaded the .iso file. I tried to burn the file to a DVD using infra recorder but it gives an input/output error. Then it fails to burn and cd drive ejects the cd.

I tried using usb stick too. But after pressing the create button, it gives an error: cannot open file as archive.

Have you tried UNetbootin?

It can create a bootable usb drive using the.iso file you downloaded. It is available for Windows, Mac and Linux. You may have more luck with it. Here's a link:
