This tutorial will teach you how to recover data from a BitLocker encrypted partition in Windows 11/10, mainly including the following aspects:
I have a BitLocker encrypted partition on my Windows 10 computer, and now I can't unlock this partition with the correct BitLocker password and BitLocker recovery key. I tried some data recovery software, but none of them helped me recover data from the BitLocker encrypted partition. My question is: how to recover data from BitLocker encrypted drive in Windows 10?
BitLocker is a disk encryption feature introduced by Microsoft in Windows Vista. Windows 7, 8, and 8.1 use the AES-CBC 128/256-bit encryption algorithm. Early versions of Windows 10 (prior to Version 1511) used the same algorithm. Starting with Windows 10 Version 1511, Microsoft introduced a new encryption algorithm: XTS-AES 128/256-bit, which offers enhanced security but is not compatible with older Windows versions and makes data recovery more challenging. As an enterprise-grade feature, BitLocker is natively available only in Windows Pro and Enterprise editions. If you are running Windows Home edition, you can use Hasleo BitLocker Anywhere to enable BitLocker encryption on your drives.
A BitLocker-encrypted partition that was previously accessible may suddenly become inaccessible, often due to file system corruption. In such cases, you can first try running chkdsk to repair file system errors, then check whether the drive becomes accessible again. Because chkdsk modifies data while repairing errors, it is strongly recommended to back up the BitLocker-encrypted drive beforehand using disk backup software such as Hasleo Backup Suite. If the drive remains inaccessible after repairing file system errors, you will need professional BitLocker data recovery software to recover lost data from the drive. Hasleo BitLocker Data Recovery is a reliable solution specifically designed for this purpose.
As a professional recovery solution, Hasleo BitLocker Data Recovery supports data recovery from BitLocker-encrypted drives—whether encrypted with AES-CBC 128/256-bit or XTS-AES 128/256-bit on Windows 11/10—even if the drive is formatted, inaccessible, failed, damaged, lost, or deleted.
1. Select the hard drive or partition where you lost your files in Windows 11/10, then click the "Scan" button to locate all BitLocker-encrypted partitions on the device.

2. A pop-up window will appear asking you to enter the BitLocker password or 48-digit BitLocker recovery key. If you don't want to enter the password or BitLocker recovery key here, just click the "Skip" button to skip it.

3. Hasleo Data Recovery will list all found BitLocker encrypted partitions on the target device. If you have entered the password or BitLocker recovery key in the previous step, the password status will show whether the password or BitLocker recovery key matches this partition.

4. Double-click the partition you want to recover data from. If you've already entered the password or BitLocker recovery key and the password or recovery key matches, Hasleo Data Recovery will start scanning lost files. Otherwise, a prompt will appear asking for your BitLocker password or 48-digit recovery key. After entering the correct credentials and clicking "OK", the scan will start.

When the scanning process gets finished, you can filter and preview found files by path and file types. When you locate the files you want, just select them and click on "Recover" button to save them to your hard drive or other storage device. If some files are not found, please click "Deep Scan" button to start the Deep Scan Recovery process, deep scan takes more time, but can find much more lost files.
