How can i open my windows in BOOTCAMP? its been more than 7months since i access windows on bootcamp by my imac, im working all the time on my mac OS, but sometimes i want to use also my windows that was installed at bootcamp, but recently when i try to open my windows on holding shift key, my imac will not prompt me anymore for options to choise either mac or windows os, how would i get back again to my windows thru bootcamp? if i delete my partation on bootcamp the empty disk space should be or can be used for mac os?
