We are just starting out on our raspberry pi learning journey and have run into a problem.
We formatted our SD card, loaded Noobs onto it with pre-installed raspbian. We then turned on the raspberry pi for the first time. It gave us the option of which OS system to load so we chose raspbian.
It then said that it was loading the software and we waited quite a while . It then said that there was an error and it couldn't load so I pressed the shift key to give us the recovery screen.
I got a whole load of code on the screen the last item of which was:
3.479801]---[end kernel panic - not syncing: VFS: Unable to mount roof fs on unknown-block (179,2)
Any suggestions as to what has gone wrong and what we need to do about it?
Thanks very much in advance.
