How to Clone HDD to a Solid-State Disk Without Reinstalling Windows

Updated on Apr 02, 2019 by Jean to Backup Utility

Installing a solid-state disk is one of the best way to upgrade Windows which we are quite familiar. However, migrating your Windows installation to a small disk must be more complicated, because the data won't necessarily all fit on the new disk. Here in this artile, you'll know how to clone to a Solid State disk without reinstalling Windows.


We've provided you with a lot of solutions about migrating hard drive to a larger one through disk clone, but when you try to migrate to an SSD, things get a little more confusing. Instead of upgrading to a bigger drive, people usually migrate or copy Windows to a smaller drive, a lot of files like photos, music, movies, and games that might not all fit on the SSD. Fortunately, it becomes pretty easy now, and you can get all these done within munites. But what do you need before migrating OS to an SSD?

What You Need for Migration

1. Backup everything and then deleting your personal files.

Your documents, movies, and music from the current hard disk should all be deleted, which will make your Windows installation small enough to fit on the SSD.

2. Clone your current disk onto the SSD, and completely wipe your current drive.

From there, all your user folders - like My Documents, My Music, etc. will be moved to the original hard drive, and restore all your personal files from the backup image. In this way, you can enjoy the benefits of high speed to migrate while keeping all your documents and files readily accessible on a second drive.

Given these troubles, many people wouldn't upgrade their Windows 7 hard drive unless they have no choice. So is there any easy and safe way to solve this problem - upgrading to a larger disk without reinstalling Windows 7 system or losing any data?

How to Upgrade Windows 10/8/7 System Hard Drive

Surfing on the Internet, you will find numerous ways to help you out. Of course, the common recommendation offered by most people is to choose a professional hard drive cloning software which can create an exact copy of one hard drive to another one, keeping all the partitions and data including the operating system intact as they were in the original (source) disk. Among the sea of software, which one is the best for your PC and the data? Here you may try EaseUS Todo Backup, professional hard disk clone software, offered by the EaseUS software, which will help you effortlessly upgrade Windows system drive such as to clone Windows 8 to SSD.

There are a variety of ways to go about this, but we've found this to be the simplest and most reliable method. The following is what you'll need:

1. Your current hard disk, with Windows, installed.

To make it easy, we'll call this disk for short - that is, the disk you're migrating from - your "current hard disk" throughout the process.

2. A solid-state disk. This is the disk you'll be migrating to.

To get a rough idea of how big it should be, go to your current disk, navigate to:

  • C:\Users\ and right-click on your user folder.
  • Click Properties, and mark down how much space that folder takes up.
  • Head to My Computer and note how much space Drive C: has filled up, and subtract your user folder's size from C:'s total.

That's how big your SSD needs to be, though I'd give yourself a good deal of free space for future updates and new programs.

3. A backup of all your data.

Since it's impossible to clone only part of a drive, you'll need to remove your music, movies, and other personal files from your current disk before migrating Windows to the SSD, which means you'd better back up your data somewhere else. Just make sure that data is safe and recoverable as we'll be restoring it later on.

4. A system migration program - EaseUS Todo Backup.

This is the program we'll be using to migrate the system to a Solid-State disk and update Windows 7. It's easy to use, can perform multiple operations at once.

These advanced settings can help you clone a drive more stable and smoothly in some special case. However, without these advanced settings, EaseUS Todo backup can still give you an exact and intact clone.

Optimize for SSD - If the destination disk is an SSD, checking this option will ensure sector alignment in the process.

Sector by sector clone - A sector by sector clone ensures that the destination hard disk/partition is exactly the same as the source hard disk/partition. It will clone all the sectors if the option is checked, even if the sector is blank. As a result, the target will be equal in size to the disk being cloned after the process. This option is found in the same step where you choose the destination hard disk/partition both in the Disk clone and Partition clone wizard.

Create a Portable Windows USB drive - This option ensures that the cloned USB system disk is able to boot normally.

Step 4: Preview and save the changes and the software will start to clone your system disk.
