Bitlocker pin (pre-boot) screen empty

Hi John,

You might be facing this issue due to corrupt system files or outdated graphics card. I suggest you to change the resolution on the computer and update the graphics card and check if it helps.

a)       Right-click the mouse from the desktop interface and select “Screen Resolution” from the menu.
b)       Check the screen resolution shown there. It should be at least 1024 X 768.

Method 1: Update video card driver.

Steps to update video card driver:
 
a.    Press Windows key + X and select device manager.
c.    Select the video card device and right click on it
d.    Now select properties.
e.    In the properties window, under Driver tab, click on Update Driver button.
f.    After the installing the updates restart the computer.

If the issue persists even after updating the graphics card driver, I suggest you to run the SFC scan and check.

Method 2:

Run a system file checker scan and then try to create system restore points check if that helps. Refer the following steps to run SFC scan.

Please refer to the steps to perform SFC Scan:

a. Press “Windows Key + Q” to open Charms Bar.
b. Type “cmd” without quotes in the search box.
c. On the left pane, right click on the “cmd” option and select “Run as Administrator”.
d. Type ‘sfc /scannow’ without quotes and hit enter.

Note: It may ask for windows installation DVD to fix and to enable SFC to make more than minor repairs. Some files saved on your computer might get deleted when fixing corrupted files.

Hope this helps.

Please post back if the issue persists and we will be glad to assist you further.
