I used the boot camp tool to create a 32GB partition and formated within the windows installer. The installer starts expanding the files then freezes and halts at various percent values. I notice the superdrive spins down then powers down before this happens. I ran the Apple diagnostic tools, holding down "D key" on boot, ran the extended tests = pass. Ran memory tests in windows 7 diagnostics = pass. Ran Ultimate boot CD 4 ran tests = pass. Is any one else having this issue? Does anyone have a solution?
