    I installed Windows 7 to my macbook pro simply using the boot camp assistant, then again simply I deleted the windows partition. I can not acces to windows but every time I open my mac, it tries to open windows and a black screen comes, saying that I need to insert a disc or something like that. How can I solve this problem ?

    Have you used Boot Camp Assistant to remove the Windows partition?

    Have you taken a look at System Preferences > Startup Disk and selected the Mac OS X partition as startup disk?

    You can choose from where to boot from via holding down the OPTION/ALT key right after the startup sound chimes.
