“Can I clone my boot disk that contains OS?”

“I have an old boot hard drive that has windows 10 OS on it, and I want to copy all the files including operating system from the bootable hard drive onto my new SSD. Is there an easy way to do that so the pc will be setup similar to how it was with the old hard drive? Or is there any recommended bootable hard drive clone software?”

Why clone the bootable hard drive?

Cloning bootable hard drive is to make an exact copy of the disk installed with an operating system. In many situations, you need to clone a bootable hard drive. Below are three common scenarios:

▶Upgrade bootable hard drive without reinstalling OS. When the current bootable disk is too smaller to hold new data, or too slow to load OS, you can upgrade it to a largr hard drive, or replace the HDD with SSD. Compared with reinstalling OS on the new disk, cloning bootable disk is more recommended since it clone all data from the old hard drive to the new one, and you can boot from the destination disk directly.

▶Back up data on the bootable hard drive. Since the bootable disk not only contains the Windows operating system, but also saves other personal data, it is important to make a complete backup of them. That can help you avoid data loss when the system disk fails or is attacked by virus.

▶Ensure the safety of multiple systems on the hard drive. You may have more than one OS on the hard drive. Generally, migrate OS won’t migrate all systems on the hard drive, at this time, cloning bootable hard drive should be the best way to transfer all systems to another hard drive safely.

Steps to clone bootable hard drive in Windows PC

Here, we will show how to clone a bootable hard drive in Windows PC step by step. Before that, you had better take a look at the following precautions:

The cloning process will erase all data on the destination disk, so please back up any required files on it in advance.
If the destination disk is smaller than the source disk, you can remove unnecessary apps or files from the source disk to make its used space smaller than the target disk space.
If the destination disk is of GPT partition style, you can convert GPT to MBR first so that you don’t need to change boot mode (from BIOS to UEFI) after clone.

Step 1. Connect the destination hard drive to your computer and make sure it is detected successfully. Install and run AOMEI Partition Assistant Professional. Click “Clone Disk” in the right menu.


Step 2. In this window, you can choose a proper disk clone method based on your disk size and click “Next”. Here we select the “Clone Disk Quickly”.


Step 3. Choose the hard disk that you need to clone as the source disk and click "Next".


Step 3. Now select the target disk and click “Next”. If it is an SSD drive, you can tick “Optimize the performance of SSD” option at the bottom.


Step 4. In the subsequent window, you can change partition size on the destination disk. After that, click “Next”.


Clone without resizing partitions: this will remain partition size on the original disk. If you are cloning large disk to smaller disk, this option will be unavailable.
Fit partitions to entire disk: the target disk partition size will be adjusted automatically to fit the entire destination disk.
Edit partitions on this disk: change partition size on the destination disk as you need.

Step 5. Hit on the “Apply” and “Proceed” to commit the pending operation.


After the clone is done, you can enter BIOS, change boot order to make the cloned disk as the first boot device so that you can boot PC from the destination disk. Or you can remove the old hard drive, and install the cloned one to replace it completely.
