this is the second time im asking this question because someone had to close my question for a reason which i still dont understand.

this is the original question Why is my files,machine,help tab missing in ubuntu 11.10?

Most importantly ,i cannot access the machine menu that should be there but isnt. im using ubuntu 11.10 with oracle 4.1.10

heres a picture of what ubuntu should look like,or maybe i am wrong, http://i.stack.imgur.com/JgM5S.png

The reason why im asking,is because id like to run a usb key inside my virtual box,but since i cannot access machine,i cant access the devices manager either.

Just for your information,ive already installed the guest additions.
