[Jorge Ernesto Guevara Cuenca <guevara.ernesto@gmail.com>]

Hello,

I ejected a usb stick without umount and doesn't boot anymore, I formatted it again, prepare like the install manual[1] says and it don't boot never again. I tried with oficial images[2] and my own images created, and ever i obtain this kernel panic message:

List of all partitiions:

No filesystem could mount root, tried:

kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

How can I use again this usb stick?
