[Fixed] BitLocker Preventing Windows Install

Why is BitLocker preventing Windows install?

If you're encountering an issue where BitLocker is preventing a Windows installation, it usually occurs because BitLocker is enabled on the drive where you're trying to install or update Windows. BitLocker is a full-disk encryption feature that encrypts the entire drive, protecting your data from unauthorized access. Here's why this can cause problems:

☛ Encryption Interference: When BitLocker is enabled, it encrypts the data on the drive. If you attempt to install or upgrade Windows on an encrypted drive without suspending or decrypting BitLocker, the installation process may be blocked to prevent data loss or corruption.

☛ Drive Locking: BitLocker may lock the drive to protect it during the installation process. This can prevent Windows Setup from accessing the drive, leading to errors or the inability to proceed with the installation.

☛ Secure Boot Requirements: Some Windows installations require Secure Boot to be enabled, and BitLocker may interfere if the correct settings are not in place. This can result in the installation being halted.

What to do if BitLocker preventing Windows install?

If BitLocker is preventing you from installing or upgrading Windows, it's likely because the drive is encrypted, and the Windows installation process cannot proceed with encryption in place. Here are some ways you can try:

Method 1. Suspend BitLocker Protection

Firstly, you can turn off BitLocker temporarily to make the drive accessible to all users.

Step 1. Go to Control Panel > System and Security > BitLocker Drive Encryption.

Step 2. Find the drive that has BitLocker enabled, click on Suspend protection, and confirm.

This temporarily disables BitLocker without decrypting the drive, making it possible to install or upgrade Windows.

Method 2. Decrypt the drive

If suspending BitLocker doesn’t work or you prefer to remove encryption entirely:

Step 1. Go to Control Panel > System and Security > BitLocker Drive Encryption.

Step 2. Select the drive with BitLocker enabled, then click on Turn off BitLocker. This will start the decryption process, which might take some time depending on the size of the drive.

After decryption, you can try reinstalling Windows.

Method 3. Disable Secure Boot

Secure Boot is a security feature in Windows that protects the integrity of a computer's boot process by verifying the digital signatures of the operating system and bootloader. Thus, if the above two methods do not work, you can disable Secure Boot and try again.

Step 1. Restart your computer and enter BIOS setup (usually by pressing F2, DEL, or ESC during startup).

Step 2. Look for the "Secure Boot" or "Secure Boot Mode" option in the BIOS menu.

Step 3. Set it to "Disabled" or "Off."

Step 4. Save changes and exit the BIOS.

Method 4. Check hard drive health

Hard drive error may prevent you from installing Windows on it. Therefore, it’s feasible to check disk errors and fix it to prepare for Windows installation.

Step 1. Open Command Prompt (run as administrator).

Step 2. Type the command chkdsk X:/f and press Enter (replace "X" with the letter of the partition you want to check for).

Step 3. If prompted, schedule a check during the next system restart.

If the four methods above are not useful, move on to the fifth one.

Method 5. Use Windows Installation Media

Actually, in addition to cleaning install the operating system, using a Windows media creation tool to install Windows from USB is also a popular way. Here is the step-by-step guide:

Step 1. Insert the Windows installation USB or DVD, restart your computer, and boot from the media.

Step 2. During the installation process, when you reach the screen to select a drive, delete the encrypted partition. This will remove BitLocker and allow the installation to proceed.

Step 3. Follow the on-screen instructions to complete the Windows installation.

By following these measures, you should be able to resolve the issue of BitLocker preventing a Windows install.
