BIOS settings/computer boot issue

[ITGyN73BqR]

I was trying to set up a dual-boot with Ubuntu and changed some of the BIOS settings, but now the computer doesn't restart.

I think the problem is that I disabled the legacy boot settings. Now when I try to start the computer I get that the power button blinks red with 6 beeps a few times before stopping. However, the computer does not boot even after waiting for 15 min.

Any idea about how to fix this?

Hi:

Did you add a video card by any chance?

The 6 beep error code has something to do with the video.

You normally get that 6 beep error message if you disable legacy mode and enable secure boot.
