ALT-option to choose which OS to boot stopped working.


i installed windows on 2010 mbp, , it's been working far, today when woke , had use windows, nothing seems happen when hold down (either) alt when booting.
filmed phone http://www.youtube.com/watch?v=jkdrfcxmbuu see problem is.

press power button, makes boot sound while hold alt down. shows mouse without 2 harddiscs.

i'm new mac, don't know if can fix easily, or have re-install windows (7). or if can fixed os x dvd came macbook pro.

if specs needed, i'm running:

2010 macbook pro 15"
i7 2.66
4 gb ram
7200 rpm harddrive
hr glossy screen


fixed! usb hub apparently stopped windows showing up. strange!
 

i had similar problem old mbp (2005 - think) keyboard did not seem work on startup couldn't change boot drive @ startup work fine once mac osx had started up. after while keyboard stopped working altogether , turned out hardware fault. not true in case.

don't know solution problem workaround open system preferences on mac , go startup disk , change windows 7 partition. restart , load windows. change mac side, open bootcamp control panel on windows , choose mac os parition, restart.

hope helps,

aly
