Safely migrate your operating system to an SSD with Paragon. This article provides a step-by-step guide and recommends a powerful alternative tool if you encounter errors during the process.
Paragon Migrate OS to SSD is a specialized system migration utility developed by Paragon Software to help users transfer their existing Windows operating system from a traditional hard drive to a solid-state drive without reinstalling Windows.
However, Paragon Migrate OS is no longer available as a standalone tool since October 8, 2025. If you want to use this feature now, you should download Paragon Hard Disk Manager.
If you encounter problems when using Paragon Hard Disk Manager, try the best alternative tool to migrate OS to SSD.
In this part, I’ll show you how to use Paragon Hard Disk Manager to migrate OS to SSD step by step.
Note: The “Copy operating system” feature is only available in Hard Disk Manager Advanced or Hard Disk Manager for Business. You may request a trial version if needed.
Step 1. Connect the new SSD to your computer. On a desktop, this usually means installing the SSD internally. On a laptop, you can use a USB-to-SATA or USB-to-NVMe adapter.
Note: If the new SSD contains any data, backup important files before proceeding.
Step 2. Install and launch Paragon Hard Disk Manager. Then click Disks and volumes from the left panel.
Step 3. Click on your current system partition and choose Copy operating system in the Operations section.
Step 4. Choose the connected SSD as the destination disk.
Step 5. Specify copy parameters as necessary.
Note: We highly recommend you not to exclude system files, but those that could take plenty of disk space, like video, music, photos, etc.
Step 6. Check the resulting disk layouts at “After changes” and click Copy now to start the operation immediately.
Step 7. After the migration finishes, shut down your computer. Physically replace the old hard drive with the SSD, or enter BIOS/UEFI settings and set the SSD as the first boot device. Restart your computer and verify that Windows loads from the SSD.
Powerful as Paragon Hard Disk Manager is, users may still encounter errors during the system migration process. Below are the most common problems and proven ways to resolve them.
1. Cloned SSD Won’t Boot After Migration
🎯 Possible causes:
🛠 How to fix it:
Enter BIOS/UEFI and make sure the SSD is set as the first boot device. Check that the boot mode (UEFI or Legacy) matches the original system disk. If Windows still won’t load, use Windows installation media to run Startup Repair or rebuild boot records with automatic repair tools.
2. Target SSD Not Showing Up in Paragon
🎯 Possible causes:
🛠 How to fix it:
Open Windows Disk Management and initialize the SSD as GPT or MBR. Reconnect the drive, try a different USB port or adapter, and avoid USB hubs. Updating storage and motherboard drivers can also help Paragon detect the SSD correctly.
3. Migration Failed or Got Stuck During the Process
🎯 Possible causes:
🛠 How to fix it:
Run chkdsk /f /r to check and repair disk errors before migrating. Make sure the used space on the system disk is smaller than the SSD capacity. Temporarily disable antivirus and close background programs during migration.
