Yes, it is possible to partition my hard drive before installing Windows. And in fact, it is recommended to partition the hard drive before Windows installation. Here are the reasons:

  • Multiple partitions can keep your Windows system and boot files separate from other personal files.
  • Easy to have an exact copy of Windows OS setup files and recover it when there are issues.
  • You can format the Windows partition separately for reinstallation.

Whether you've just bought a new computer or installed a new hard drive, the hard drive is most likely to come with one partition. The common methods - Disk Management and Diskpart are not available in case of no system installation, which means you cannot create partitions directly with them. In this case, you need to use a reliable disk partitioning tool.

EaseUS Partition Master is a third-party software offering many practical tools for partition tasks. For example, you can use the Partition Manager tool to resize/create disk partitions and delete all partitions on SSD. In addition, its New Disk Guide feature allows you to partition a new hard drive within a few clicks.

Before starting, you need to create EaseUS Partition Master bootable USB on another computer and set the new PC to boot from it since you have no OS on the new computer. Click the following link to find out how to do it:
