I have a older model IBM Think-pad and I have successfully installed Ubuntu 9.04 and found that it is no longer supported. I have burned a copy of 12.10 onto a CD and tried without installing onto a desktop. When I have placed the same cd into the Think-pad, it does not recognize there is anything on the cd such as the OS. Are there any suggestions
Alternative to a CD, you can boot and install from a USB (link). The BIOS will similarly have to be configured to boot a USB drive before the hard drive with the existing operating system.
