Are you looking for a safe and efficient way to clone a hard drive from boot? When the hard disk exceeds its service life or cannot meet users' needs, it needs to be replaced with a new hard disk. Many users clone a hard drive from boot to save time and effort. This article gives a detailed guide to cloning a hard drive from the boot. Let's dive into learning.

Why Clone Hard Drive From Boot

Now more and more people tend to clone the disk when they need to upgrade to a new hard disk or when the computer fails to start normally. Cloning a hard drive saves users the trouble of reinstalling the operating system, and all installed applications, games, videos, and other personal files can be restored, which is very convenient. Hence, the two occasions are typical as follows:

Cannot turn on the computer normally: Your system files have become corrupted, making your system unbootable, so you must use a bootable USB clone hard drive to get your PC back to normal.

Cloning process failed: Some running programs may conflict with the cloning process, so you need to clone the disk from a bootable USB for cloning.

However, how to clone a hard drive from boot since Windows doesn't come with a built-in cloning feature? You need to use a third-party tool, EaseUS Partition Master.

We need to make a bootable USB flash drive and then use the bootable USB flash drive to clone the target hard disk. As for specific methods, please refer to the following steps:

Before we start, we need to prepare the following:

  • Another Windows computer that boots successfully.
  • Install EaseUS Partition Master on the work computer.
  • A USB drive. You need to back up USB files in advance in case of data loss.

Guide 1. Create Bootable USB

After backing up the USB flash drive, insert the USB flash drive into the prepared work computer, install EaseUS Partition Master, and follow the instructions below to create bootable USB:

Step 1. To create a bootable disk of EaseUS Partition Master, you should prepare a storage media, like a USB drive, flash drive or a CD/DVD disc. Then, correctly connect the drive to your computer.

Step 2. Launch EaseUS Partition Master, and find the "Bootable Media" feature on the left. Click on it.

Step 3. You can choose the USB or CD/DVD when the drive is available. However, if you do not have a storage device at hand, you can also save the ISO file to a local drive, and later burn it to a storage media. Once made the option, click the "Create" button to begin.

  • Check the Warning message and click "Yes".

When the process finishes, you have successfully created an EaseUS Partition Master WinPE bootable disk. Now, you can manage your hard disks and partitions through the bootable drive whenever the computer fails to boot normally.

If you have RAID drives, load the RAID driver first by clicking Add Driver from the menu bar, which can help you add the driver of your device under WinPE environment, as some specific device cannot be recognized under WinPE environment without drivers installed, such as RAID or some specific hard disk.

Guide 2. Change the Boot Order

Before cloning, you need to boot your computer from the bootable USB drive. Here are the steps:

Step 1. Insert a new hard disk, insert the bootable USB into the computer that cannot be started normally, start the computer, and press the BIOS button (F10/F2/F12/F1/DEL) after seeing the first screen.

Step 2. Enter "BIOS setup," select "change boot order," and select the bootable USB as the boot disk.

  • It won't hot image your drives or align them, but since it's coupled with a partition manager, it allows you do perform many tasks at once, instead of just cloning drives.
