I'm currently using a 13 inch MBP with standalone windows 7 on the hard disk. For some reason, when I boot up the laptop it just gets stuck in a white screen (sometimes a folder with a question mark gets displayed). To boot up, I need to hold the alt button, select windows (the ONLY option...) and hit enter. Is there any way to edit the boot mechanism in any way to get windows to boot up automatically? I tried the Mac OS install disk "Startup utility" but there's no Windows to select. Also, when the Mac OS install disk is in the drive, I boot up, hit alt and select Windows; it will load the Mac DVD anyway and get stuck somewhere. So basically, the laptop is desperately trying to boot the Mac OS ... Anyone who had this occur / any advice? Thanks in advance.
