Secure Boot and boot menu screen resolution

[rockman2017]

Hi.

My BIOS update is: F.43 Rev.A

I have an issue related with the boot menu screen resolution:

1. When secure boot is enabled it presents this screen resolution:

2. When secure boot is disabled it presents this screen resolution:

Why does this happen and  How do you fix it?

Note: I have used the BCDEDIT command with parameters as GRAFICRESOLUTION but it's same behavior within BIOS secure boot!

I hope your reply.

Thanks.

I recommend you utilize the recovery media that you created (if not, order here) to revert back to the OEM. So that I may support you further.

You can check if the recovery media is available online on www.hp.com/drivers by entering the exact model no. of your laptop. To find the exact model no. click here: http://hp.care/2bygf7l

Hi dear.

This issue occurred after updating my BIOS and later installation of new operating system on VHD!

Always I have used several operating systems on VHD with this HP laptop model and I've never had a problem with that!

I look forward to other solution alternatives.

Thank you :manfrustrated:

I Would appreciate a solution based on my present condition.

Note:
The original operating system of this laptop is Windows 7 where it was upgraded to Windows 10!
There, other operating systems were installed on VHD without altering the original file system .

Thank you.
