About 50 % of the times I try to set up a dual boot between an NT 6.0 OS and PE 2.0 the setup fails: instead of booting the boot.wim PE image Windows is booted and crashes during login. I then remove the whole dual boot setup and do it again in EXACTLY the same way and it succeeds. Why does the first setup always fail approx. 50 % of the time ? Why does it succeed after doing the thing (remove entry, delete image, put same image back, recreate boot entry) again, exactly the same way as the first time ?
