I've installed Windows 7 on a new SSD and removed the old boot drive and am using it as a data drive. That old drive has a 100mb System Reserved partition which Disk Management shows as Healthy (Active, Primary) as well as a much larger data partition. The System Reserved partition is using drive letter E: and the data partition is using G:.
Windows Explorer is showing the System Reserved partition as an active E: drive which is pretty useless since that space really can't be used. Moreover, I need to assign E: to another drive. So, what's the best way to remove (or take "off-line") the System Reserved partition so I can re-assign E: and perhaps even recover the 100mb of space it is taking up (though that's less important).
