HP Computer Traditional Mode Gray State

This is a normal situation, indicating that some options want to select some functions that must be enabled rather than disabled. You can try again or cut a picture, and I can tell you what settings you have to open in the bios to choose that option.

The default traditional boot source in BIOS is disabled; ; 2. Select the secure boot configuration under security, turn off secure boot first, and then turn on legacy support; ; 3. Please note that to restart the machine after modification, you need to press the number (4048) to confirm the modification. This number appears randomly, and it may not be this number in the next revision. I hope the above reply can help you.
