I've got a mid 2011 MBA with Windows 7 running via Bootcamp. In Lion, i've enabled Filevault 2.
Normally, when I turn my laptop on, I first enter the filevault password before the laptop boots into OS X.
If I am trying to boot into Windows, I hold down alt/option, select the Windows partition and let the laptop boot. However, what seems to happen is, the filevault screen that normally shows when I first turn my laptop on shows, I enter the password and I seem to end up in OS X! I then need to restart, hold down alt/option and select the Windows partition again. This then gets me in.
Is this normal behaviour? Or is there something I need to change?
