Windows 10: Can't make Windows 10 PC enter BIOS when restarting

I want to test my bootable USB Media.


I am trying to restart my Win 10 PC from a bootable USB media, but I can't make the PC stop at the BIOS to select the USB drive.


On start-up, the screen comes up that says hit f12 to go into Boot Options, and I tap f12 repeatedly, but no matter how many times I tap f12, the PC just continues to the normal boot into Windows 10.

Hi Geoff,

To access BIOS settings under Windows 10 operating system, please follow the steps below:

• Click Start, then click Settings.
• Click Update & security, select Recovery then under
  Advanced startup, click Restart now.
• Select Troubleshoot, then Advanced options, then click
  UEFI Firmware Settings.

Let us know how it goes.

 

Windows 10 Tweaks

Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

• Open a new Explorer window.
• Click View in the ribbon.
• Click Options.
• Under General, next to “Open File Explorer to:” choose “This PC.”
• Click OK

Blank screen when entering BIOS, but Windows Boots fine on ASUS CH7

Hello,

I wanted to check the bios settings and I have suddenly found out, that when I press DEL to enter BIOS, the display is blank. Monitor is On, it has signal, but with blank black screen. Computer starts normally, beeps, displays the AMI initial screen and normally boots into Windows. If I press DEL however, instead of going to BIOS, I get blank screen.

Baseline:

• AMD Ryzen 2700X / ASUS Crosshair 7 WIFI
• BIOS 2008
• Windows 10 PRO 1809

Troubleshooting done:

• Monitor to any other display output (only this one is on, others are off)
• Different VGA
• BIOS reset - did not help, although it was reset. I got message that BIOS was reset, press F1 to enter bios, but then - the same issue.
• BIOS Flashback update - After pressing the button, it blinks 3 times, then turns on, which should be OK. BUt nothing is happening - the led on USB stick does not blink. Whan I interrupt, the PC works as before.
• EZ Update in Windows - after submitting to update the bios, it restarts, but then enters the BIOS, which is - blank. After restart, all works as before (with black BIOS)
• Entering BIOS from Windows (Shift-Restart) does have the same effect

I am out of ideas now - the PC works, just can't get into BIOS to change anything. Of course, now, I have the default settings loaded because of few BIOS resets.

Interesting is, that when in BIOS, I am getting 0d on the postcode - changes to this after entering the BIOS. In the manual, this value should be reserved for future AMI BIOS errors.

Any hints?
