I successfully partitioned my new imac and started the windows install with xps2, however at the stage of entering the key I discovered I was missing a digit..sooo I had to shutdown the imac manually. I managed to get macosx operating again and removed the partition in the hope of starting again with another disk (xps3) only to discover that as soon as put the disk in and started the installation (through bootcamp) I just got a black screen with a flashing white cursor in the top left hand corner. I have tried reinstalling macosx but still have same problem (I didn't wipe the drive though). Can anyone help me fix this??? Please!
