I am currently running Ubuntu out of a memory stick plugged into my laptop. Whenever I turn on my laptop with the stick in, instead of Ubuntu loading I get an error message on an otherwise totally black screen telling me that there has been a kernel panic and that it cannot locate the root fs. It will not respond either to the keyboard or the off switch - I have to wait until the battery runs out. I don't understand why this is so - I still have Windows installed on my PC, and it works perfectly. I hope that someone can explain to me what the problem is and how to fix it(if possible).
Thank you in advance.
