Macbook air stucked on Black screen
I had recently installed Windows 7 on my Macbook Air using Boot Camp.
It works great for a couple of days then when i opened it last night it stucks on the start screen.
What i mean start screen is when i press the power button and then it lightened and the black screen went on with an underscore blinking.
Nothing loads after that and won't even get through windows/mac os
Can anybody help me with this problem?
I tried ALT/OPT -Didnt work!
I tried pressing X- Didnt work!
HELP!
MacBook Pro, Mac OS X (10.5.7)
