This is a rather "bare" kernel line.  Compare it to the kernel line from
F12 above.  You probably need to specify at *least* the root= part as
well for the kernel to find the correct root partition to use when you
boot.  It even shows you this in the example in the comment above that.

Need more information from around this error to determine the actual
problem.  If your kernel is unable to find the proper root partition,
who knows what file it might try and find to execute, possibly resulting
in the error message you are seeing.
