When we have problems gaining access to our systems it is difficult to gather information, let alone fix any problems. Here we will cover common causes and solutions to ‘manjaro wont boot’.

By default your system will have multiple TTYs, with each corresponding to an Fx key. Your desktop is assigned to one as well - most often F1. You can chang…
