I'm working with Windows Server 2008 Web Edition SP1 on a dedicated box (with KVM access). As soon as I convert the system disk (C) to dynamic and reboot I get this message: Error loading operating system. I'm converting the disk to dynamic so that I can mirror the system drive with a second drive. I've actually went through the mirroring process before, everything works fine until I reboot. Could a simple conversion to dynamic stop the system from loading? Although this smells like a software issue, could it be hardware related? Any suggestions?
Hardware: SuperMicro H8SMU (motherboard), AMD Opteron 1216HE, 4GB RAM, 2 x WD Caviar RE 16 WD2500YS.
