Have an mSATA for C Drive but I notice my E Drive appears to have a system partition. How do I get my C Drive to contain the system. What does "System" in parenthesis mean on my E Drive? My C Drive also has unallocated space. Is that normal? Should my C Drive have a system reserved partition? Not sure exactly what happened when I upgraded the mSATA. My other two drives are HDD. My intentions were to contain the boot and system files on the mSATA and just keep the HDDs as extra storage. This is what my Disk Management reveals.
