Windows 7 on bootcamp installation problem

hi all,

i just had a new imac and was trying to install a windows home premium OEM 64 bit on bootcamp. installation is going fine until the completion stage where your suppose to set up winodws for first use, all it did is become a blank/ black screen and nothing happens. i waited for a long time until i decided to install it one more try. no luck. i tried to remove the partition and partitioned it again on bootcamp and had another go at installation, still no joy. have anyone had similar problems? i just prefered to install a windows natively instead of using parallels. can someone help me please? i would really appreciate it.
