When getting a new HDD or SSD for your computer, you have the option to clone or do a clean install. By default, the new drive will only be used for personal storage unless an operating system is installed on it.

There are two ways to install the Windows operating system onto your hard drive, and which one you choose is a matter of personal preference. You can either:

You've probably seen one or two of these methods recommended, but you may still have questions. That's what this article is for. It will walk you through the clone vs. clean install decision process and recommend a simple disk cloning tool.

What is Disk/Partition Cloning?

Disk/partition cloning refers to the process of copying the entire contents of a hard drive to another storage medium, including the Windows operating system, updates, installed programs, personal files, games, and data.

It's fast, and many people prefer it as an alternative to cloning or doing a clean install, since it also copies hidden files that might not get duplicated in a manual copy-paste operation.

The storage medium can be a removable media or the hard drive of another computer. Make sure it has enough memory to hold the contents of your source drive in full. This also copies unneeded files and junk folders, so Disk/Partition cloning should only be chosen if you plan on transferring the entirety of your old drive to the new one.

In addition, the source drive and target drive must be connected to the same computer via SATA-to-USB adapters, either internally or externally. Microsoft does not have an official cloning software, so you'll need a trustworthy third-party cloning app. We recommend using the Disk Copy utility.

As shown, the program needs permission to format the target drive before it can proceed with the clone. A successful clone results in the source and target drives having the same layout/partitions after the operation.

"Windows Clean Install" refers to a fresh installation of the Windows operating system. This method involves removing any existing operating systems on a computer and installing Windows from scratch. It ensures that the system is free from pre-installed software, viruses, or malware, providing a clean and new environment. Before performing a Clean Install, it is typically necessary to back up important data, as this process will erase all content on the hard drive.

A clean install of Windows means formatting the current hard drive and then installing a new Windows operating system using the Windows installation media. It's like starting from scratch, restoring your computer to a brand-new state.

Though it's the more time-consuming cloning option, it has its advantages. A Windows clean install is recommended to resolve computer memory issues and performance problems or to get rid of viruses and malware. You can think of a clean install as a way to restore your computer to like-new condition, which explains its effectiveness in addressing the issues you previously encountered.

Any data, programs, and other important information on the hard drive will be completely erased. As shown here, this will remove files, settings, and other apps from the version of Windows that came with your PC.

Clean install of Windows

Thus, it is generally recommended to create a backup before initiating a clean install or an operating system upgrade. Failing to do so can result in data loss. The backup should be stored on an external drive or another computer system to prevent losing files and programs during the reinstallation process.

Cloning vs. Clean Install: Which Is Right for You?

When you buy a new HDD or SSD, you have the choice to clone or do a clean install. Both are great options for upgrading your Windows operating system, but they're better suited to different situations, meaning one method will be more appropriate than the other in certain circumstances.

When to use the Disk/Partition Clone method:

    • You want to replicate the exact configuration of your PC on another computer.
    • You need to perform multiple installations of the same system OS and settings across several computers.
    • You want to restore an existing hard drive to its original settings and configuration.
    • You need to migrate critical data and disk contents to a new disk.

You should use a Windows clean installation when:

    • Solve issues with your current computer operating system.
    • Remove malware and other security threats.
    • Upgrade to a new version of the Windows OS without any side effects.
    • You still experience performance issues even after uninstalling some programs.

For system or disk cloning, choose the “Disk Copy” tool.

As far as the results are concerned, both cloning and clean install options are effective. However, a clean install can be overwhelming when you have to manually back up your data and files to an external storage medium. Hence, a clean install is recommended when you have issues with your hard drive.

Otherwise, cloning is better and faster. Cloning involves creating an exact replica of your system data and configuration to use as a restore option or to replicate on another computer, thus saving you the time it would take to install everything manually.

However, Microsoft doesn't have an official cloning software. Thus, you need to look for a third-party cloning solution that can effectively replace your hard drive, upgrade the disk, and migrate the OS version. The tool "Disk Clone" is one such utility that can do all these. Like other Windows cloning software, it bypasses the time-consuming reinstallation process.

Why use a Disk Copy Tool?

    • A reliable cloning option with an intuitive interface that anyone can understand.
    • Capable of creating a 100% replica of Windows operating system versions efficiently.
    • Ensures zero file loss when transferring data and configuration settings to another SSD or HDD.

How do I use a disk cloning tool?

Step 1. Download, install, and run the Disk Copy utility on your computer.

Click “Disk Mode,” then select the hard drive you want to copy or clone. Click “Next” to continue.

Select the hard disk to clone

Step 2: Select the target disk.

Note: If you are copying or cloning a source disk, the target disk should be at least as large as the source disk, or larger.

Select the target disk

Step 3: Check and edit the disk layout.

If the target disk is an SSD, check the option “Target is SSD.”

Confirmation Information

If prompted to erase the contents of the target disk, click OK.

Check disk layout

Step 5: Click “ Proceed ” to start the cloning process.

Click “Proceed” to start the cloning process.

Conclusions

Whether you choose to clone or do a clean install depends on the state of your computer system. If your Windows OS and hard drive are running smoothly, you only need disk/partition cloning software. Otherwise, opt for the Windows clean install option when your OS and hard drive performance/operations are giving you problems.

However, getting hold of software that can clone your system perfectly and provide backup for a clean install is the best solution to this dilemma. Disk Utility has always been our tool of choice. It's not too technical, so why not give it a try?
