After installing windows 7 on my new macbook pro, the mac operating system is not booting anymore. Am now using only windows 7 without the mac operating system,what do I do to get my operating system back?
Hold down the Alt key when you power-up and it should show you a list of bootable partitions/devices, Holding Ctrl key when you select an OS makes it the default.
