Can I clone Windows 10 to a smaller SSD without reinstalling OS?

Yes, you can easily clone/move/transfer Windows 10 to a smaller SSD or hard drive without reinstalling OS. Windows reinstallation will be a tough task for most Windows users, as it requires complicated skills and takes much time. Therefore, the ideal way of replacing an old hard drive for computer is cloning existing operating system to the new disk directly.

It is well known that SSDs are much faster than traditional hard drives and they've been gradually getting less expensive over the last few years. As a result, SSDs are chosen by more and more users to improve computer performance. The suggested way to make the best of the fast speed of SSD is using it as the primary disk where operating system and applications are installed. In this way, you will get faster speed to boot into Windows as well as use installed programs.

However, a fresh reinstallation of Windows on SSD will be a time-consuming process. You need to install Windows first, then install drivers and applications. In some cases, you may also need to customize some settings for the newly installed system. This might be the major reason that many users are reluctant to replacing hard drive with an SSD even though they know such operations can greatly speed up computer. If you are one of them, you can follow the guide discussed below to transfer Windows 10 or other Windows operating systems to new SSD/HDD easily and safely.

  • Migrate Windows intelligently: Operating system will be transferred to target hard drive or SSD without closing currently running system. Thus, you can transfer Windows OS to new SSD in the background. What's more, the target disk is allowed to be smaller than the old system disk.
  • Backup partition to image file: Full backup and incremental backup are supported when you back up a partition to an image file.
  • Clone hard drive with bad sectors: when hard drive develops bad sectors, you can try making a sector level clone for the disk. The cloning process can skip bad sectors.

Step 5: Click Hot Migration button. Then DiskGenius starts to clone Windows to target disk.

Hot Migration, the default way of moving OS, uses Windows VSS technology, enabling the migration process to be performed in the background without shutting down current system. Thus, while migrating system, your computer can do other tasks, which is quite convenient.

If you choose "Reboot to WinPE", your computer will reboot to DiskGenius WinPE edition and finish cloning task. It is usually used as an alternative solution when hot migration is not available.

Either way of migrating OS does not damage original operating system, so you can choose one based on your needs.
