Reinstall setup software on bitlocked computer

Muzza1970 · ‎05-13-2026

Hi,

Having trouble returning computer back to factory settings.

The hard drive is bitlocked and I cant proceed. The windows installation is asking for drivers to connect to the internet to finish the download.

Is there any other way to return it to factory state. It is a HP ProBook 455 G(

Hello @Muzza1970 ,

Welcome to the HP community.

For cases related to BitLocker issues, please contact Microsoft Support.

The only way to recover your PC's BitLocker key is if you printed it out or exported it to your Microsoft account when you first set up your PC.

Find your BitLocker recovery key - Microsoft Support

Without the key, you will have to clean install Windows on the encrypted drive so you can use your PC again.

Best regards

Steffen Baier

Im happy to reinstall windows as a clean install, but it is not letting me do it.

I cant seem to find a file, that allows me to take the computer back to its orginal factory settings as a clean install.

When I get a certain way into the windows install it is asking for network drivers and wont proceed until they are installed and I have no idea what ones are required

Hello @Muzza1970 ,

When booting the Laptop you should have the option to press F11 to enter recovery mode and then Select Troubleshoot > Reset this PC

Or the cleanest way is to HP Cloud Recovery Tool via another PC.

If no other volunteers reply, I suggest you contact our Support organization in your region. Details are in my Signature.

Hi, @Muzza1970

I'm assuming that you have a Probook 455 G9 because you typed a ( instead of a 9.

You can install the Wi-Fi driver from a USB flash drive so that Windows can proceed, but here's the problem...

I need to know what model Wi-Fi adapter HP installed in your notebook before I give you the procedure to do that.

Enter your notebook's product number in the search window at the link below, and it should provide the part number and model number of the Wi-Fi adapter that HP installed in your notebook.
