Now, I will show you the whole process of move OS to new drive in 3 parts.
Part 1. Preparation jobs
► Connect a new hard drive
First, you must connect or install a second hard drive on the PC. Desktops tend to support multiple hard drive slots, while laptop usually only have one hard drive slot, so you need to prepare a SATA to USB adapter to connect the drive to the computer.
► Initialize the hard drive
You need to initialize the new disk and create a partition; otherwise it won’t work in Windows. Please note that since the partition style must be the same as the boot mode, in order to avoid changing the boot mode after moving, please make the partition style of the new disk the same as the source disk.
► Check the power supply
Power contact issues can cause migration to fail and cause unnecessary trouble.
Part 2. Migrate OS to a new drive step by step
Step 1. Install and open Partition Assistant Professional. Click Migrate OS to SSD in the left pane. Don’t be fooled by its name, it works on HDD as well.
Step 2. Select the new hard disk as the target disk here. If there are partitions on the target disk, check “I want to delete all partitions on the disk 2 to migrate system to the disk” and select Next.
Step 3. You can drag the two-way arrow to resize the system partition, or just type the desired number in the box below.
Step 4. Read the Note in the window, it is important to you.
Step 5. Click Apply and Proceed to execute the pending operation.
Part 3. Boot Windows from new drive successfully
If the computer can only have one hard drive installed, then you can start Windows directly after replacing the new hard drive. But if you can install multiple hard disks, to boot Windows from the newly migrated hard disk, you need to change the boot drive.
Start the computer and follow the on-screen prompts (usually DEL, ESC, F1, F2, F8, F9, F10, F11, F12) to enter the BIOS setup. In the BIOS menu, press the arrow keys on the keyboard to enter the Boot tab and change the boot order to have the new boot drive as the first boot device. Then, follow the instructions given in the BIOS utility to navigate to the Exit tab and select the Exit Save Changes option to save your changes to the boot order.
Now, you can see what is the best software to move OS to new drive without reinstalling. Whether it’s transferring the Windows to a new hard drive to upgrade an old one or replace a faulty one, AOMEI Partition Assistant Pro can do it for you easily. If you haven’t tried it yet, don’t hesitate.
