My Pi gets stuck on boot-up with the message "A start job is running for LSB: Raise network interfaces (timer / no limit)". The timer keeps counting up, bot the job never completes, and thus the Pi never finishes booting. How can I abort this process so that the Pi continues booting?
Backstory: I'm running Raspbian Jessie on a Pi B, and after the first successful boot, I wanted to configure the wifi dongle for my home network. Since the home network does not broadcast its SSID, I couldn't use the Network Prefs UI. I tried editing some config files, but now the Pi is stuck on boot.
