Helping people with computers... one answer at a time.
Windows 7 added basic partition management tools that make operations, such as removing a partition and extending another to use the space, very easy.
I have a Windows 7 system and by mistake, I have created two partitions. I would like to remove the added partition without doing damage to the original partition. I have not been able to find information on this subject.
In the past, this required third-party tools, but as you're using Windows 7, you're in luck: everything that you need is already on your system.
I'll show you, step by step and in video, how to remove that partition and how to recover the space that it occupied into the adjacent drive.
The disk management tool that's always been a part of Windows was upgraded in Windows 7 to allow you to do exactly the kind of partition management task that you're talking about.
Right-click "Computer" - either the icon on your desktop, or the item in the Start menu - and click Manage:
(I've renamed "Computer" on my machine to be the name of the machine - "DemoMaster" in this case - to help me keep all of my machines straight. )
In the Computer Management tool, click Disk Management:
The disk manager will show a representation of the physical drive:
As you can see, this particular drive has three partitions:
The "System Reserved" partition where administration information is stored.
The "C:" partition, your system drive and typically the drive on which Windows is installed.
The "Example Partition (E:)" which is the partition that we want to get rid of.
Your computer's disk will almost certainly be quite different, but the concepts here are the same.
Right-click the partition that you want to delete and click Delete Volume...
(Volume, in this scenario, is a Windows synonym for partition.)
You'll get a warning:
Important: Deleting a volume or partition deletes all of the data that's inside of it. All of it. If there's any data in that partition that you want to keep, STOP! ... and back up that data first.
Click Yes when you're ready to delete the partition and everything inside of it.
The partition becomes marked "Unallocated":
Right-click the immediately adjacent partition, the C: partition in our case, and click Extend Volume...
That'll bring up the Extend Volume Wizard:
It'll list the available areas on the disk where you can add to the volume that you're extending, or as in our case, it'll simply default to using all of the only available area.
All that you need to do is click Next and then Finish.
Before deleting that partition, you might want to put some thought into whether or not you might use it instead. Should I partition my hard disk? covers the issue; be sure to read the comments there for various points of view.
You'll want to make sure that the data on your partitions is properly backed up. How do I backup my computer? has thoughts on what steps you might take.
Today, I'm going to show you how to remove an extra partition on a hard drive using Windows 7.
We start by right-clicking on My Computer or whatever your computer happens to be named.
You would also find this on your Start menu as 'Computer' or 'My Computer'; right-click on that and select 'Manage'; select 'Disk management' and here we can see on our hard drive, we actually have three partitions: our C: drive, the system reserved partition, and then this example partition I've created that we want to remove.
It's very simple. It's a two-step operation: select it to make it current; right-click on it and say 'Delete volume'.
Now remember, any time you're working with partition management tools, the risk of or in this case, you are explicitly erasing all of the data on those volumes or partitions; we definitely do want to delete all of the data here.
Now, we need to extend the existing C: drive into the space we just released. You'll note that it only works because these two spaces are adjacent to each other. We right-click; we say 'Extend volume'; we have selected the space that's available next to it; which happens to be the unallocated space; we say 'Next'; we say 'Finish' and now, all of a sudden, our C: drive has grown to encompass both of the original C: and E: drives, including space used by the partition we just deleted.
