Better Way: Replace Laptop Hard Drive Without Reinstalling Windows

#Hard Drive Cloning Software#Disk Upgrade Tool#No Windows Reinstallation#Simple & Easy

As mentioned, you must reinstall the required apps and the Windows operating system to use the laptop normally. This is troublesome because it is time-consuming. Are you wondering how to replace a hard drive while keeping the operating system? So, is there a way to replace a laptop's hard drive without reinstalling Windows and its programs?

The answer is in the affirmative. You can clone your old hard drive to a new one to avoid reinstalling Windows and applications. Cloning allows you to copy data from one hard drive to another, including Windows files, system settings, programs, documents, etc.

To clone your old hard disk to a new one, you must use professional cloning software because Windows does not have a built-in tool with a cloning feature. In that case, EaseUS Disk Copy, a professional disk cloning tool, comes to help.

EaseUS Disk Copy is a multi-functional cloning program for Windows 11/10/8/7. It allows you to clone your system, disk, and partition. And it enables you to clone a hard drive with bad sectors thanks to its sector-by-sector clone technology. In addition, it lets you migrate the operating system from HDD to SSD and SSD to SSD and transfer the C drive to a new SSD without reinstalling Windows and applications.

You can perform the following steps to clone your old hard disk to a new one.

Prior Notice:

• The "Sector by sector copy" asks the size of your destination disk to be at least equal to or larger than that of the source disk. Leave this feature unchecked if you wish to clone a larger hard disk to a smaller hard disk.
• All data on the destination disk will be completely erased, so take care.

Step 1. To start copying/cloning an entire disk to another, choose this disk as the source disk under "Disk Mode" and click "Next".

Step 2. Choose the other disk as the destination disk.

Step 3. Check the disk layout of the two disks. You can manage the disk layout of the destination disk by selecting "Autofit the disk", "Copy as the source" or "Edit disk layout". 

• "Autofit the disk" makes some changes by default on the destination disk layout so that it can work at its best status.
• "Copy as the source"does not change anything on destination disk and the layout is the same as source disk.
• "Edit disk layout" allows you to manually resize/move partition layout on this destination disk.

Tick the "Check the option if the target is SSD" option to put your SSD in its best performance.

A message now appears, warning you that data will be lost. Please confirm this message by clicking "OK" and then click "Next".

Step 4. Click "Proceed" to officially execute the task.
