My mac is MBA with OS X 10.6.8 and on which W7 is installed using the Bootcamp. My problem is Windows 7 BSODs(Blue Screen of Death) or has become unbootable after installing the Bootcamp updates. It happened about three months ago and at that time the Windows system was brought back to the state before the update was installed. This time I tried the udate again and see the same problem. I am wondering if any remedy has been devised by now.
