Step #1: Prepare Download System Rescue, Install New Hard Drive

To successfully clone an operating system to another hard drive without having to reinstall, the first thing you need to do is download a reliable system cloning software and prepare your new hard drive.

#1. Download a professional system cloning software

If you search for system cloning software online, you may not get what you want. Here, we recommend that you try professional disk cloning software - AOMEI Backupper Standard.

It's a practical disk cloning tool that aids in cloning hard drives or operating systems to another drive. It enables you to clone your boot drive to a new SSD and copy data from one hard drive to another without losing any information. Moreover, it features powerful sector-by-sector cloning technology, which allows you to clone a hard drive with bad sectors and migrate only the OS partition to an SSD.

It also has powerful cloning features that let you clone an operating system to a new disk.

2. Install and initialize the new hard drive

When cloning the OS to another disk, the new disk must be equal to or larger than the size of the system C drive. Also, you need to initialize the new disk with the same partition style as the system disk: MBR-to-MBR or GPT-to-GPT.

Next, we can start creating our new disk:

**Step 1.** Install your new hard drive or SSD properly.

**Step 2:** Restart your computer and open Disk Management. Find your new drive.

Step 3: Right click on the new disk and choose to format it as MBR or GPT.

Initialize the new disk to be the same as the system disk.

Step 2: Perform System Clone - Clone OS to HDD/SSD with AOMEI Backupper

The entire cloning process takes about 30 minutes for a 120 GB system disk. You can complete it in four steps:

Preview:

• "Clone by copying partitions" requires the target disk to be at least as large as the source disk, or larger. Uncheck this if you want to clone a larger disk to a smaller one.
• All data on the target disk will be completely erased, so exercise caution.

1. To start copying/ cloning an entire disk to another disk, select the disk to be copied under Disk Mode, and click Next.

Step Two: Select the disk you want to copy the data to.

Step 3. Check the partition layout of both disks. You can adjust the partition layout of the target disk as needed, choosing to "Adjust Automatically," "Copy Source Partitions," or "Edit Partitions."

• Automatically resize partitions makes some changes to the layout of the target disk by default, so it's in the best state.
• Copy as source doesn't change anything on the target disk and its layout remains the same as the source disk.
• Edit partition layout lets you manually adjust/move the partition layout on this target disk.

Check the "Enable TRIM on solid-state drives" box for best performance.

A message appears, warning you that your data will be lost. Confirm this message by clicking OK, and then click Next.

Step 4: Click “Continue” to start the task proper.

That's it! You've now cloned your Windows system to the new drive with a reliable tool.
