Creating a partition in Windows 10 during installation is a straightforward process. Begin by booting from your Windows 10 installation media. When you reach the partition selection screen, choose “Custom: Install Windows only (advanced).” Here, you’ll see existing partitions and unallocated space. Select the space you want to partition, click “New,” specify the size, and apply. After that, continue with the installation process, and Windows 10 will install on your newly created partition.
How to Create Partition in Windows 10 During Installation
Installing Windows 10 with a custom partition gives you more control over your disk space. Follow these steps to create a partition while installing the operating system.
Step 1: Boot from Installation Media
Insert your Windows 10 installation USB or DVD, and restart the computer.
After booting, you may need to press a specific key (like F12, F2, or Delete) to enter the boot menu and select your installation media. This initiates the Windows installation process.
Step 2: Choose Installation Type
When the installation menu appears, select “Custom: Install Windows only (advanced).”
This step allows you to manually manage partitions, giving you the freedom to adjust disk space according to your needs.
Step 3: Select Unallocated Space
Identify the unallocated space where you want to create a new partition.
Make sure you have enough space for Windows 10 and any other software you plan to install. Unallocated space is free space that’s not yet part of any partition.
Step 4: Create a New Partition
Click “New,” enter the desired size for your partition, then click “Apply.”
Windows will format the new partition, preparing it for installation. Be cautious about the size; ensure it’s sufficient for the system and future updates.
Step 5: Proceed with Installation
Select the new partition and click “Next” to start installing Windows 10.
Your installation will continue, and Windows 10 will be set up on the partition you’ve created. This can take some time, so be patient.
Once you’ve completed these steps, Windows 10 will continue to install on your newly created partition. After installation, you’ll have a functioning Windows 10 system, and your disk will be organized according to your specified partitions.
