Dell Migrate User's Guide
Disabling BitLocker
If BitLocker encryption is enabled on your hard drive, the erase process cannot proceed. Windows uses BitLocker to encrypt your drives, which helps protect your files and folders from unauthorized access if your device is lost or stolen. This option is enabled by default on some Windows systems. After the encryption is turned off, click Try Again on Data Assistant.
You can unlock your hard drive by using the following steps. It is recommended that you unlock your hard drive in the following order:
- Disable device encryption using Device encryption settings
- Disable BitLocker
- Unlock the files using an encryption password
- Unlock the files using a recovery key
NOTE: Depending on the version of your Windows operating system, these steps might differ.
For more information, see Automatic Windows Device Encryption/BitLocker on Dell Systems.
