Tutorial | Separate OS from Programs Without Losing Data

Are you wondering if it's a good idea to have more than one partition on your hard drive and separate OS from programs? The answer is yes! The partition where the OS is installed is the system partition(usually C drive). The system partition and the OS on it provide essential support for running a computer. It manages various resources like hardware and software on your computer with multiple services.

As for other programs and apps, they usually are not in the same partition where the OS is since it might cause slow running and unexpected errors to your PC. Therefore, if your computer only contains one partition, you should find a way to create one or more to save your programs and apps. Lucky for you, this article from EaseUS will give you a straightforward guide to help you.

Here's an example of a user who wants to migrate the OS to an SSD so that the program is separate from the Windows system.

Stage 1 - Create a New Partition (2 Ways)

Now, if you only have one hard disk on your computer and you are not planning to buy another HDD or SSD, here's what you can do to separate the OS from programs. First, create a new partition from the only partition you have. Here, we provide you with 2 ways to do this.

(I will use C drive as an example for you to better understand.)

Way 1. Use EaseUS Partition Master

Partitioning the drive may be a little bit difficult for Windows beginners because several factors need to be considered, like different file systems. To create a new partition easily, you'll need help from a reliable third-party tool. Here, I recommend you with EaseUS Partition Master Professional.

This powerful software has a user-friendly interface and multiple functions that can help you comprehensively manage your disks and partitions. You can basically complete every partition-related operation with EaseUS Partition Master. Now, check the guide below.

Part 1. Resize the C drive to a smaller partition

Step 1: Locate and select target partition to shrink

Go to the Partition Manager section, right-click on the partition that you want to shrink and select "Resize/Move".

Step 2: Adjust to shrink partition

Use your mouse to drag the end of the target partition to shrink partition space.

You can also adjust the partition size box to shrink the target partition. Once done, click "OK" to continue.

Step 3: Execute operation

Click the "Execute Task" button and "Apply" to keep all changes.

Part 2. Create a new partition from unallocated space

Step 1. Launch EaseUS Partition Master. On the main window, right-click on the unallocated space on your hard drive or external storage device and select "Create".

Step 2. Adjust the partition size, file system (Choose the file system based on your need), label, etc. for the new partition and click "OK" to continue.

Step 3. Click on the "Execute 1 Task(s)" button and create a new partition by clicking "Apply".

Watch the following video tutorial and learn how to create a partition in NTFS, FAT, or EXT file system.

Besides this way, you can also split the C drive, and the tool will prompt you to create a new partition directly.

Way 2. Use Disk Management

For those who don't like third-party software, your Windows computer has a built-in tool called Disk Management. It also has the ability to partition the hard drive. Follow the steps below to create a partition from the C drive.

Step 1. Right-click the Windows icon and select Disk Management.

Step 2. Right-click the C drive and select "Shrink Volume".

Step 3. Confirm the amount of space you want to shrink. Then hit "Shrink".

Step 4. Right-click on the unallocated space you just created, and select "New Simple Volume".

Step 5. Follow the on-screen guide in the New Simple Volume Wizard to finish the process.

Sometimes, you may encounter the "New Simple Volume" option in Disk Management being greyed out. If you are experiencing the same problem, read the article below.

Stage 2 - Move Programs to the New Partition

Now that you have more than one partition on your hard drive, it's time to move programs from the C drive to the D drive. In order to complete this easily, you can still use EaseUS Partition Master. It provides an additional feature - AppMove, which can transfer your programs and apps from one partition to another. Here are the detailed steps.

Step 1. Select your targeted partition and click "Split Partition" from the Feature List.

Step 2. Resize the size of the two split partitions and click "OK".

Step 3. All the introduced changes to the disk layout will be pended until applied in Execute Task.

Step 4. After applying the changes, you successfully split the partition into two partitions.

Notes:

• EaseUS Partition Master supports split partition on basic disk only. It cannot split the dynamic volume.
• Only the non-hidden partition can be split.
• The unused space of the operating partitions should be more than 5% of the total partition space.
