Why clone Windows 7 to new hard drive?

There are many reasons why you might need to clone Windows 7/8/10 to a new hard drive.

  • Make a system backup so that you can quickly and easily restore your customized Windows operating system if your main drive fails.

  • Suffer a slow system boot and want to upgrade to a new faster SSD from a traditional hard drive.

  • Get a new computer and want to use the customized Windows on it to replace the old computer.

In such cases, you will probably want to clone the original Windows OS drive onto a new hard drive.

Best software to copy Windows 10/8/7 to SSD or HDD

So how can you transfer Windows 7/8/10 partition to new hard drive easily instead of reinstalling Windows operating system and other installed applications on this partition? By far, the easiest way is to use a professional disk cloning software like AOMEI Partition Assistant Professional. It is designed for Windows 7/8/8.1/10/XP/Vista (32/64-bit) users.

With this software, you can clone entire hard disk, including the Windows partition and other data partitions, to the new HDD or SSD drive. Besides, it develops a specific feature for cloning Windows called "Migrate OS to SSD Wizard", which can migrate only Windows 10/8/7 partition to a new disk as easily as possible.

How to clone Windows 7 to new hard drive step by step?

In this part, we will show you how to migrate/clone Windows OS from one disk to another in detail.

Before you proceeding:

  • Make a backup of the original system drive via AOMEI Backupper in case that some unexpected and uncontrollable issues occur during the Windows migration.

  • Verify that there is an unallocated space on the target disk, which should be equal and larger than used space of the Windows partition.

  • If you are planning to migrate Windows OS drive from MBR disk to GPT disk, check whether your motherboard supports UEFI boot mode, since you need to change boot mode from Legacy BIOS to UEFI after migration is completed. The vice versa is also true.

Then do as follow:

Step 1. Install and launch AOMEI Partition Assistant Professional. You will get disk partition information as the picture below. Then, click "Migrate OS to SSD or HDD" on the left side under Wizards column.
