Aspire V5 431P F2 does not enter BIOS and wont boot

Hi

I made a change to the BIOS to try to boot a linux live cd (turned off secure boot and changed to legacy) and the system no longer boots windows.

I am not surprised by this but I can't get into the BIOS to put right my changes. The "press F2 " screen is only present for about 0.5 seconds and after hours of trying with the laptop keyboard and with a usb one I can't get back into the bios.

If I can't get in with F2 is there another way to get the bios back into the right state for windows?

Is there a battery I can remove or a jumper to set the bios back to a default? Or another key press I don't know about?

Thanks for your help

FIXED !! :-)

My wife found on another thread that holding the power button for 2 minutes changed the bios mode and it did!

power on and hold power button for 2 mins (even after the power light goes off)

power on again and the Press F2 screen is gone

boot recovery key and UEFI options are back so entered bios and defaulted.

Thanks to everyone who helped me

On a different computer, download the windows 10 tool and create 64bit/32bit media (select BOTH).

Insert media in to your V5-431P and then Boot the media (restart your computer)

Look for Repair My Computer.

After you select "repair my computer", navigate in the menu to UEFI settings....so the computer will restart and go to UEFI settings.

Load BIOS defaults (F9) and then save/exit (F10)

not sure if the UEFI/BIOS trick works when BIOS is on Legacy mode.

by the way, you can try to remove the main battery using the release latch, it's on the back cover of your laptop; press power button 2-3 times without the battery and try to boot to BIOS.

you can also remove the 2 ram sticks (you need to unscrew 2 screws), put the battery back and boot your laptop, normally this will gives a BIOS error and your can enter it pressing F2.
