i am completely new to this OS so i have no idea what i'm doing. so far i have encountered two problems that i have no idea how to fix. i'm hoping that someone here will help...
the first problem is that it woun't shutdown correctly, the computer displays the Kubuntu screen and stays that way

i have to press the on button for three seconds to shut down my machine
the second problem is i can't get my floppy to mount

i keep getting

the error message mount:/dev/is not a block device
