Windows 10: Can't access BIOS, Can't boot from USB/DVD

Hi
My problem is that I can't access UEFI Firmware settings or Boot from USB/DVD in the Advanced startup.
They are missing. What can I do? I want to go back to windows 8.1 (Don't have windows.old folder), but it gives me an error when I install it when windows is running. That's why I want to boot from DVD, but I can't.
Help?

:)

 

Accessing BIOS without a keyboard

I was able to access Firmware settings but still can't access BIOS. Keyboard is still not operational. Want to enable Virtualization. I also want to change USB settings. Need to Boot to USB floppy at times. Also My recovery scheme
requires me to be able to boot to a CD/DVD.

Thank you very much for your help!

By RTC Cell he means just the normal battery? And what does it even do?

 

It will reset your Bios so that fast boot is not enabled and it should then allow you to see the the press X key for setup.

 

Just unplug your computer while it's running and it should now show the bios when rebooted for the first time.

 

Although unlikely, this method could directly cause damage or failure of hardware components. Much better to use a method that does not have that potential for damage *Wink

 

Like resets the BIOS settings etc? It doesn't rollback to the default BIOS? By that I mean to the BIOS that the PC had when I bought it. The BIOS was updated like a year ago and I don't want to do it myself.

 

No. Removing the battery will NOT roll back the bios version. The update is permanent. Removing the battery will merely return the bios to it's default state for the CURRENTLY installed bios version. Nothing to worry about *Smile

 

This worked for me.

Note: Some system SBIOS's incorporate a feature called compatibility boot. These systems will detect a non-UEFI-enabled firmware VBIOS and allow the user to disable secure boot and then proceed with a compatibility boot. If the system contains a system SBIOS the supports compatibility boot, the user will need to disable secure boot when asked during boot process
Instructions for manually disabling secure boot:
1) Power down the system
2) Remove the NVIDIA Add-in card
3) Boot the system using integrated graphics
4) Enter CMOS settings. CMOS settings can usually be accessed during boot, typically by pressing one of F1, F2, F8, F12, or Delete (depends on the system firmware) Alternatively they can be accessed in Windows 8 as follows: http://www.makeuseof.com/tag/how-to-...ws-8-computer/
5) Set Secure Boot to disabled
6) If there is an option, set CSM (or compatibility or legacy mode) to enabled.
7) Save the new settings
8) Power down the system
9) Install the NVIDIA Add-in card
10) The system should now boot

No, he means the little silver disc cell that powers the CMOS, which is the BIOS memory. Disconnecting this battery should clear all user settings and the BIOS will be reset to the default values.

 

Welp, I removed the back cover and I found the RTC Cell, sadly, there are like 2 or 3 cords on it, blocking me from getting the cell out. I don't want to remove those cords, since I might fck up. Aren't there any other ways to access BIOS?

 

As the computer is booting up, switch the power off from your power supply to simulate a power outage, and your computer will allow you into the bios on the next reboot.

 

Can you confirm the following:

• We're talking about the HP Pavilion DV6 6053ea
• You're pressing the ESC key when you turn it on, before Windows starts booting
• Pressing the ESC key doesn't give you a Startup Menu where you can press F10 to enter BIOS or F9 to enter Boot Menu
