End kernel panic problem

Question

I'm a newbie, trying to connect a gps to my raspberry pi 3 bit. After rebooting I can't get any further, and receive the message

End Kernel panic - not syncing: VFS: Unable to mount roof fs on unknown-block(0,0)

I'm trying to use the rescue system but every time I using a sudo command It says sudo: not found.

Answer 1

Your SD card is faulty, or at least the data that's on it is flawed/has issues.

1. Try burning your OS image (Raspbian) on the SD card

2. If that doesn't work, try another SD card.
