This means the boot manager is not recognizing the keyboard. If you ever do this again try the non-gui version of the Ubuntu boot manager. While I could change the boot option to Windows in Ubuntu (I am not going to duplicate ready web content on that) what I don't know is how to change it back easily. To do that you'll have to research the boot manager you installed.
This is just background information. Skip to the third paragraph to answer the real queston.
I got a new macbook the other day and also learned how amazing Ubuntu is (a distribution of linux). I installed windows on my mac (through boot camp) and then installed Ubuntu (I made a partition with space from the windows partition). The only problem is that when I boot up (holding the option key) I only see two operating systems: Mac OS X and windows. When I click on the windows partition there is a choice to boot into windows or Ubuntu (if nothing selecte it will automaticly boot from Ubuntu in 15 seconds) but the problem is I can't use the arrow keys to select what operating system I want to use so it boots into Ubuntu in 15 seconds. This means I cannot use windows.
I want to make a 4GB partition for Ubuntu and later make another partition for windows while using the boot camp assistant. I understand that you cannot use disk utility to partition the start-up disk (even though boot camp assistant manages). Without using the boot camp assistant how do I partition my hard drive?
