I have the MacBook Pro with me and the scenario is such that I am having Windows 7 on the MacBook. Well at first I was having the Windows Vista and there was no problem with the notebook. When I tried updating the Windows i.e. from the Windows Vista to the Windows 7, on the notebook I found that in the Windows 7 mode the system hangs on the login screen. I do not know why I am getting the same in the Windows 7 mode. Well there it is asking me to press the Ctrl+Alt+Delete key and the thing with the MacBook Pro is that I do not know how to make this thing work. Has anyone has come across such a situation. Well I tried again installing the Windows Vista on the MacBook Pro and this tie too I was getting the same issue. Now this time too on the Vista I am stuck with the same Ctrl+Alt+Delete combination. I really do not know what can be done so that I can get out of this drastic situation. Any suggestions in this respect will be really appreciated. Hope to get the reply soon.
