Step by step: Move Windows to another drive

How to transfer Windows to another drive? In the content below, we will discuss the three most important stages of moving a Windows system to another drive.

Stage 1. Before transferring Windows to another drive

Before operating the work of migrating Windows, please note the following programs:

If your computer is a desktop computer, please use a screwdriver to install the new hard drive into the host computer; if your computer is a laptop, please prepare a SATA to USB adapter, then connect the new hard drive to your PC.

Please make sure that the capacity of the target hard drive is larger than the space used to install and run Windows, or you will not be able to move Windows to it.
The power connection must be stable, or the migration may fail due to power loss.
If the target hard drive is new, don't forget to initialize it and set the partition style to be the same as the old hard drive.

Stage 3. How to boot Windows from the new drive

As we all know, BIOS and UEFI are two common boot modes of computers. BIOS is an old boot mode suitable for Windows systems before Windows 8. It has good compatibility and supports MBR disks. As an alternative to BIOS, UEFI is currently the most popular boot mode. It has higher security and supports GPT disks. Let's see how to boot from it after successfully migrating Windows.

Situation 1. Boot new drive from UEFI

You need to do the following to change the boot order (UEFI boot mode):

Step 1. Restart the computer and repeatedly press F1/F2/F3/F5/Esc to enter the UEFI settings.

Step 2. (UEFI boot mode)Turn to the Boot Menu and set the new drive as the boot drive in the boot priority section.
