I updated the PI to allow USB boot and had flashed the latest install image (ChannelsDVRServer_PI4.img.gz) to a 2TB Western Digital My Passport.
Now after moving the drive to a USB 3 port on the PI and plugging in the PI - status updates flew across the screen until it seems to have stopped (been 30 mins now)
The last thing on the screen is:
Started Update UTMP about System Runlevel Changes.
Any ideas how to get the install to complete?
And not sure if this is helpful, but the PI is in the official Raspberry PI case and there are two lights on the front, the left one is solid green and the right side is red.
