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).

  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.

Perfect. That's what I thought, but wanted to be sure. Now, to recover the 100mb "unallocated", do I just "extend" the large data partition? It's giving me a warning that doing so will convert the basic disk to a "dynamic" disk. I don't care since this isn't a boot disk, correct? –  jalperin Mar 25 '11 at 1:53
    
I'm not sure how it works with Disk Management. If you try this with GParted, I could be more helpful. :( –  Zian Choy Apr 10 '11 at 0:52

Also, any ubuntu/deb livecd will have 'disk utility' which handles these kind of tasks easily. (no need to apt-get gparted if it's not already installed)
