Clone Windows 11 26H2 to SSD - BitLocker & TPM Guide

Windows 11 26H2 enables BitLocker device encryption and TPM-backed security on every compatible PC. A normal clone can copy the files but leave the new SSD asking for a recovery key or refusing to boot because the encryption keys are tied to the old hardware layout.

This guide explains how to clone Windows 11 26H2 to an SSD while keeping BitLocker, TPM, and Windows activation working.

26H2 Boot and Security Layout

UEFI and GPT are required. 26H2 drops Legacy BIOS support on new installs.
BitLocker device encryption is on. The system volume is encrypted by default.
TPM holds the keys. The firmware must have TPM 2.0 enabled.
Recovery partition may move. 26H2 uses a larger recovery image that can shift the layout.
Secure Boot is required. 26H2 enforces Secure Boot on new installs.

A clone that changes the partition order or drops the recovery partition can break BitLocker. The tool must preserve the layout exactly or re-encrypt after the copy.

Inspect the Windows 11 26H2 partition layout in Disk Management

Check BitLocker and TPM First

Open BitLocker settings. Confirm whether device encryption is on or off.
Check TPM status. Run tpm.msc and confirm the TPM is ready.
Suspend BitLocker. Pausing encryption lets the clone read the files plainly.
Get the recovery key. Save it to your Microsoft account or a USB drive.
Keep the old drive connected. The TPM binds keys to the current hardware during suspend.

Suspending BitLocker is the safest approach. It stores a plain-text key protector that survives the clone, and you can resume encryption after the new SSD boots.

Check TPM and BitLocker status before cloning

Choose the Right Clone Mode

Use intelligent clone if you suspended BitLocker. It reads decrypted files and is faster.
Use sector-by-sector if BitLocker stays on. It copies the encrypted volume as raw data.
Preserve the partition layout. Do not merge or resize the recovery and EFI partitions.
Keep GPT and UEFI. The target must be GPT, not MBR.
Avoid sector-by-sector on smaller targets. Raw copy needs an equal or larger SSD.

If you clone an encrypted volume with sector-by-sector mode, the recovery key will be required on the first boot because the TPM measurement of the new drive differs.

Clone Windows 11 26H2 to SSD

Qiling Disk Master detects Windows 11 26H2 and keeps the GPT layout and EFI partition intact. It offers both intelligent and sector-by-sector modes so you can match the BitLocker state.

Step 3. Select the destination SSD and confirm that its data will be replaced.

Step 4. Choose intelligent clone if BitLocker is suspended, or sector-by-sector if it is still encrypted.

Choose the clone mode for the encrypted system

Step 5. Click Proceed, wait for the copy to finish, then shut the machine down before you remove any cable.

Boot and Re-encrypt the SSD

Set the SSD first in BIOS. Keep Secure Boot on and TPM enabled.
Enter the recovery key if asked. The first boot may request it after a sector-by-sector clone.
Wait for the first boot. Windows rebuilds the device encryption profile.
Resume BitLocker. Re-enable encryption from the BitLocker settings.
Check activation. Run slmgr /xpr to confirm Windows is still activated.

If Windows asks for the recovery key repeatedly, suspend BitLocker, clone again with intelligent mode, and resume encryption after the SSD boots.

FAQs About Cloning 26H2

Do I need to decrypt BitLocker before cloning?

No. You can suspend BitLocker or use sector-by-sector clone. Full decryption is the slowest option.

Why does the cloned 26H2 SSD ask for the BitLocker recovery key?

The TPM measurement changes because the drive hardware changed. Enter the key once and Windows re-binds to the new SSD.

Can I clone 26H2 from MBR to GPT?

26H2 already uses GPT on compatible hardware. If the source is MBR, convert it to GPT first with mbr2gpt.

Will activation survive the clone?

Yes, if the motherboard and TPM are unchanged. A motherboard change may require reactivating with your Microsoft account.

Should I use UEFI or Legacy after cloning 26H2?

Always UEFI. 26H2 requires UEFI, Secure Boot, and TPM 2.0.

Back Up Before the Clone

Cloning an encrypted system carries extra risk. Create a full backup before you begin so you can restore if the SSD will not boot.

Watch the video tutorial below to back up Windows and restore it if the clone fails.

Step 2. Save the image to a drive other than the target disk and start the backup.

Choose a folder on another drive for the system image

Step 3. Click Proceed to start the system backup and wait patiently until it finishes. You can also tick Shut down the computer when the operation is completed to power off automatically.

Step 4. If the SSD will not boot, restore the image to the original drive and clone again with the correct BitLocker mode.

Conclusion

Cloning Windows 11 26H2 needs care because BitLocker and TPM tie the system to the hardware. Suspend BitLocker and use intelligent clone, or keep encryption and use sector-by-sector clone with the recovery key ready. Preserve the GPT and UEFI layout, resume encryption after the first boot, and verify activation.
