Answers to every
WinToHDD question.

This error usually means the program cannot read the current disk configuration. Fix: (1) Right-click WinToHDD → "Run as administrator". (2) Open Disk Management (Win+X) and make sure all disks are Online. (3) If a disk shows "Offline", right-click → "Online". Then restart WinToHDD.

A black screen after cloning usually means the boot partition wasn't correctly transferred. Boot from a Windows USB → Command Prompt → run: bootrec /fixmbr, bootrec /fixboot, bootrec /rebuildbcd. On UEFI also run: bcdboot C:\Windows /s S: /f UEFI. WinToHDD Pro handles boot repair automatically.

If WinToHDD does not recognize your SSD: (1) Check it's visible in Disk Management — initialize it if needed. (2) Make sure it's not encrypted or locked. (3) Try a different SATA port or USB adapter. (4) Update your disk controller driver. NVMe drives require WinToHDD v5.0 or newer.

Stuck at 0% is almost always a permissions or VSS issue. Fix: (1) Run as Administrator. (2) Open services.msc and confirm "Volume Shadow Copy" is Running. (3) Temporarily disable antivirus — some AV tools block VSS snapshots. (4) Ensure the target drive has no write-protection.

This occurs when source is GPT and target is MBR (or vice-versa). Fix: open Disk Management, right-click the target disk, choose "Convert to GPT Disk" (UEFI systems) or "Convert to MBR Disk" (Legacy BIOS). Note: converting wipes all data on the target.

1. Download & install WinToHDD. 2. Launch as Administrator. 3. Click "System Clone". 4. Select source drive (current Windows). 5. Select target drive. 6. Choose partition scheme (keep same as source). 7. Click Start — clone takes 5–20 min. 8. Swap drive or change boot order in BIOS and power on.

1. Download a Windows ISO. 2. In WinToHDD, click "Reinstall Windows". 3. Browse to your ISO. 4. Select the Windows edition. 5. Select the target partition. 6. Click Start. WinToHDD reinstalls Windows without needing a USB drive or disc.

1. Connect a USB drive (32 GB+ recommended, USB 3.0). 2. In WinToHDD, click "Windows To Go". 3. Select your Windows ISO or current Windows. 4. Select the USB as target. 5. Choose partition scheme (GPT for UEFI). 6. Click Start. After 10–20 minutes you have a fully bootable Windows USB.

Yes — "New Installation" mode supports creating a bootable USB with multiple Windows editions. Add each ISO separately, assign partitions, and WinToHDD creates a multi-boot menu automatically. Available in both Free and Pro editions.

Yes. WinToHDD fully supports Windows 11 including TPM 2.0, Secure Boot, and UEFI. Use WinToHDD v6.0 or newer for full Windows 11 support. The latest v7.0 includes specific optimizations for Windows 11 cloning.

WinToHDD works seamlessly on Windows 10 — no special steps. Both 32-bit (x86) and 64-bit (x64) versions are supported. Make sure Windows is up to date before cloning to avoid activation issues. WinToHDD preserves your Windows 10 license key during clone.

Yes. WinToHDD supports cloning Windows 7 (32-bit and 64-bit). Since Windows 7 is end-of-life, we recommend upgrading — but WinToHDD fully handles it. Old versions (v2.x, v3.x) are available in the archive for very limited-spec systems.

Yes. WinToHDD fully supports UEFI firmware with Secure Boot. It correctly clones the EFI System Partition (ESP), Microsoft Reserved Partition (MSR), and Windows partition. After cloning, the drive boots with Secure Boot active — no BIOS change needed.

WinToHDD is completely safe. Developed by Hasleo Software with over a decade of history. The installer is digitally signed with an EV Code Signing Certificate. VirusTotal consistently shows 0 detections. No bundled software, no ads, no telemetry. Download only from this official site.

No. WinToHDD operates entirely locally on your machine. The only network activity is an optional version check on startup (can be disabled in settings). No account required for Free. For Pro, license validation is a one-time online check — no ongoing data collection.

Yes. WinToHDD performs a bit-level clone including license information. On the same hardware, Windows activates automatically after cloning. If you also replace the motherboard, use "Troubleshoot → I changed hardware on this device recently" in Windows activation settings.

Both are from Hasleo Software. WinToHDD focuses on full system cloning between internal drives. WinToUSB specializes in creating Windows To Go bootable USB drives. WinToHDD includes Windows To Go as one of several features. For everything beyond USB creation, WinToHDD is the better choice.

Closest free alternatives: (1) Macrium Reflect Free — discontinued for new licenses in 2024. (2) Clonezilla — powerful but requires Linux live USB. (3) AOMEI Backupper Free — limits clone features to paid tier. WinToHDD Free remains the most capable free option because it clones while Windows is running — no bootable media required.

Yes — both are Hasleo Software products. EasyUEFI is a dedicated UEFI boot entry manager. They complement each other: after cloning with WinToHDD, use EasyUEFI to set the cloned drive as default boot option without entering BIOS. Both have free editions.
