When things fail early in a boot process it is possible to get to a troubleshooting console. Before the initial blue splash screen appears you need to press the ‘c’ key on your keyboard. You have only have a small window of time to press it so bang that thang until the console appears.
Once at the console type ’help’ to get a list of commands available.
You can also review all available built in console variables by running ’config’.
You can then dig around, view variables and troubleshoot to your hearts content. Typically you will be directed here by 2Pint Software support staff.
