I have noticed that when I launch Windows 7 on a double boot system it sometimes looks like the machine reboots twice. That was a bit annoying, but maybe it was just a false impression...
I had a power problem today and the machine entered an endless reboot loop. After I fixed it, I just booted to Windows 7 and set the default system to be Windows 7 and the timeout to be 5 seconds. This replaced the Bauhaus Windows 8 OS selection screen with the even more Bauhaus Windows 7 one and, I hope, also prevented the same problem from happening.
Conclusion: if you do not have recovery tools handy, do not try Windows 8.
