On my Dell Latitude E6500 laptop installed Server 2008 in dual boot with my production Windows 7 environment.
Now, I actually need both environments intact for different reasons. I had installed the dual boot to Windows Server 2008 from within Windows 7 so that is how the boot manager got installed.
This weekend, I was working with demo scenarios and wound up rebuilding my environment a bunch of times.
Low and behold, at some point I booted my laptop from the Windows Server 2008 DVD and launched setup which rebuilt my server 2008 environment just fine.
Well, when I restarted the laptop, Boot Manager was nowhere to be found and the laptop went straight into server 2008. My production environment!!!!
So I interrupted the boot process, and restarted the laptop and selected last known good configuration. From here, my system detected that there was a start up issue and proceeded to repair it.
Now the laptop grants me the dual boot capabilities like before I mucked it. Ahhh… old fixes still work.
