Windows – How to remove “system reserved” partition from a former Windows 7 boot drive now used as secondary, data drive

windows 7

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).

Best Answer

  1. Go to Computer Management
  2. Under Storage, select Disk Management
  3. Right-click on E:
  4. Select Delete Volume

If "Delete Volume" is disabled, then you will have to use something else like GParted.
