Cannot install Windows on my Mac
I am sorry For not Responding For the Last few days.Unfortunately i had to format and reinstall Lion to install win 7.The hard drive was set up in such a way that it could not create a Boot Camp partition  even if only 20GBs of the 250 was used.

After Formatting the Drive as A journaled mac OS partition,I was able to install Win 7.

BTW i Could not make any changes to the drive before formatting.New partition,Restore etc. were all grayed out.
