Why partition Lenovo laptop hard drive in Windows 10?

Partitioning is a process to divide a physical disk into several independent drive partitions. When you boot a new Lenovo laptop for the first time, usually, you’ll find there’s only 1 partition – the C drive there. So, next, you need to partition the hard drive to create other partitions including D, E, and F. But why should we do this? Here, I list the top 3 reasons.

1) Better data organization: After the hard drive on a Lenovo laptop is divided into several partitions, you can manage your data more easily. For example, you can put the system-related files in the C drive and put other files in the D, E, and F drive.

2) Run multiple operating systems on the laptop: If you want to install multiple different operating systems on the Lenovo laptop, you should have several independent partitions to install the OSes.

3) Minimize the threats of data loss: If you put the OS files and other personal data in different drives, then, you can suffer from less data loss when you encounter a system crash that asks for OS reinstallation.

[2 Ways] How to partition a Lenovo laptop hard drive in Windows 10?

As mentioned above, it’s necessary and recommended to partition the Lenovo laptop hard drive the first time you use it. But how to? I believe most laptop users have never partitioned an SSD or HDD on their own. So, this time, I’ll use the most explicit words to explain it.

Method 1. Partition the hard drive via Disk Management

Windows 10 has its built-in program named Disk Management to perform different operations including disk partitioning, disk format, and disk initialization. Now, learn to partition a laptop hard drive with this useful tool.

1. Right-click on "This PC" and go to "Storage > Disk Management".

2. Right-click on the only partition – the C drive – and select "Shrink Volume".

3. Determine the amount of space to shrink and hit the button "Shrink".

4. After the shrinking completes, you’ll get a piece of “unallocated space” next to the C drive. Right-click on the unallocated space and select “New Simple Volume” from the results. Then, follow the onscreen guide to finish the rest steps.

To create more partitions, just repeat the steps above.

Method 2. Partition the hard drive with third-party software

How to create partitions in Lenovo laptops on Windows 10? Apart from Disk Management, another tool you can try is AOMEI Partition Assistant Professional. It’s a powerful third-party disk manager and especially does well in disk partitioning. If you think Disk Management is too complex and tedious, you might as well try this software to create partitions in Lenovo laptops in only a few clicks.

Step 1. Install and launch AOMEI Partition Assistant Professional. Then, right-click on the C drive and select "Split Partition".


Step 2. In the following window, you can customize the size of the source partition and new partition by adjusting the length of the 2 green bars. After that, click on "OK".


Note: If it’s an SSD partition, remember to tick the option "Allow partition alignment to optimize the performance of SSD".

Step 3. Hit "Apply > Proceed" as the screenshot displays to commit the operation.


If you want to create multiple partitions, you can try the feature of "Quick Partition" to create at most 10 partitions at once. If there is already a partition on the target disk, "Quick Partition" will remove it which causes data loss. So, make a backup first. When you quick partition a hard disk, you can freely customize the sizes and change their labels.

By comparison, the latter one is a more advanced tool as it’s easier to use and meanwhile, saves much time. Meanwhile, other features including free space allocation and partition health check are also included by this very software. If you want to use it on Servers, you can try the Server edition.
