I am trying to upgrade my PC to 12.04, so I downloaded the .iso desktop file to burn onto a CD or DVD.
Before creating the disk I first made a bootable USB stick (using pendrive), this worked fine in one PC but not in the one I need to upgrade, I suspect due to BIOS not supporting this feature.
So I have tried to create both a boot CD and DVD, using various burning programs:
- Using Windows 7, right click on the .iso file
- ImgBurn, selecting the write image file to disk option.
In every case the CD or DVD just has the one .iso file written to it, there is no file structure.
However, if I look at the USB stick I created from the same .iso file it has the files I expect to see, and it works. So what is going wrong here, I've never had this issue in the past, and am totally out of ideas.
