If you want to clone system hard drive but don’t want to waste time to reinstalling all things, you can try method in this post to clone hard drive without reinstalling.
If your Windows system is placed on a mechanical hard drive, the computer will struggle to load huge files or run many apps at the same time after a few years of use. To address this issue, the ideal solution is to switch the HDD to an SSD, which has a significantly quicker data read-write speed than the HDD.
Usually, users can clean-install Windows onto the target disk, but you will need to back up all personal data, add the new drive, and other applications on it, and then reset everything to the way it was. It is time-consuming and inconvenient. If you wish to skip all of these processes to directly set your target disk bootable, we recommend cloning the system hard drive to the destination disk.
If you don't have an ideal choice of reliable cloning software, here we recommend you AOMEI Partition Assistant Professional, a tool that is specifically designed for Windows computers to solve the problems of disk and partition. This tool has two ways to clone the system hard drive:
▶ Migrate OS to SSD This feature can migrate the system and its associated partitions to a new disk. You can use a familiar Windows system environment on the new disk and install new programs.
▶ Disk Clone Wizard This option clones the operating system, all apps, and files from the old hard drive to a new disk. So you don't need to reinstall any apps and keep all as before.
The operation is quite simple for all users, and this tool supports Windows 11/10/8/8.1/7/XP systems, with no disk brand limitations. The only note is if you clone from GPT to MBR or MBR to GPT, after the cloning, you need to change boot mode.
Now we’ll show you how to clone the system hard drive to your target disk. First, we’ll show how to clone the whole disk.
Step 1. Install and launch AOMEI Partition Assistant Professional. Click "Clone" in the main interface, and select "Clone Disk".
Step 2. Choose the operating system hard drive as the source disk and click "Next".
Step 3. Select the new drive as the destination disk, and then click "Next".
Step 4. Then, you can check the source and destination disk in the next window or change to "Sector to Sector clone", and click the "Confirm" button to continue if there is no problem.
Here, you can also click the "Settings" button to adjust the partition size on the destination disk or tick "4k alignment" to improve the reading and writing speed of the SSD if the target drive is SSD.
Step 5. When you go back to the main interface, click Apply to execute the progress.
Step 1. Click “Clone” on in the top toolbar, and choose “Migrate OS”.
Step 2. Choose an unallocated space on the new hard drive, and then click "Next" to go on.
Step 3. In the pop-out window, you can resize the partition, and assign a drive letter to it. Click “Next” to proceed.
Step 4. A helpful boot note will appear. Read it and click “Finish”.
Step 5. Click “Apply” in the main interface to execute the pending operation.
After the clone, you need to change the boot disk to the new disk. Restart your computer, enter BIOS, change the boot order and make the new hard drive the first boot device. Then you will be able to boot the computer from the target disk.
Using a reliable tool to clone system hard drive is not as hard as you thought. Besides mirroring hard drive with operating system, AOMEI Partition Assistant is a disk and partition manager, it can be used as disk management as you can resize/delete/create/format/check/merge partition and also convert a disk to MBR/GPT without deleting partitions.
What’s more, it has more practical features like moving folders and installed apps, converting file systems between FAT32 and NTFS without formatting, etc. And you can choose the Server Edition if you’re using Windows Server 2022/2019/2016/2012(R2)/2008(R2)/2003.
