• Which version of Ubuntu you’re installing (including which flavour)
• Whether you have network connectivity
• Hardware stats, including CPU, RAM, GPU, etc

• How long your install took to complete
• Whether you have auto login enabled
• Your disk layout
• Whether you chose to install third party codecs
• Whether you chose to download updates during install
