BIOS won't go away

Thanks for all of this and I will keep going through the steps. But in regards to the early questions I have answers:

There are no Boot Option Priorities at all. Launch CSM is Disabled.

Can't see the hard drive mentioned anywhere in BIOS. 

Battery had been holding charge and the charger works.

Also can't remove the battery from this model Laptop. Its ASUS if that helps at all.

Hi Rayna. I'm Greg, an installation specialist, 10 years Windows MVP, and Volunteer Moderator here to help you.

What is the BIOS Boot Priority order set to? If a UEFI BIOS then it needs to be WIndows Boot Manager. If a legacy BIOS it should be the hard drive. Is the hard drive showing up at all anywhere in BIOS Setup?

Report back BIOS settings for UEFI, CSM, Legacy BIOS, Secure and Fast Boot, and Boot Priority Order. Examine how to reset BIOS to Defaults to be prepared to try this next.

Has your battery been holding a charge? Does the charger work properly?

Unplug power and remove battery, press and hold power button for 30 seconds to release all power from circuitry, plug back in and power up to see if any change.

I will give you steps to access the Repair Mode to try all repairs to get Windows started, and if not to do the automated Reset or the superior Clean Install after rescuing your files. I will be standing by to help as needed and will not let you fail.

1. Use whichever method works in this link to access Advanced Startup Options: https://www.tenforums.com/tutorials/2294-advanc.... Easiest may be to force shut down the PC (by holding in the power button) three separate times to trigger the Startup Options. If one of these methods work, then go to Step 3.
2. If none of the other methods work it may be necessary to Create Windows 10 Installation Media on another PC following the steps in the middle of the downloads page here: http://windows.microsoft.com/en-us/windows-10/m... Make sure to uncheck the box for Recommended Settings to choose only the licensed version.

Insert media, boot it by powering up PC while pressing the BIOS Boot Menu Key: https://www.sysnative.com/forums/hardware-tutor...

Choose the boot device as a UEFI device if offered, then on second screen choose Repair Your Computer. If the media won't boot you may need to enter BIOS/UEFI Setup (pressing key given in chart in link above) to turn off Fast Boot or Fast Startup first. There is always a way to get the media booted and I will guide you until it does, even if necessary to reset the BIOS to defaults via several methods.

3. In the Advanced Troubleshooting options try to System Restore to a point before the problems began, try the new Uninstall Updates button, then Startup Repair, then if necessary from Startup Settings try to get into Safe Mode with Networking, or lastly Safe Mode.

If Startup Settings aren't available you can force Safe Mode from the Command Prompt following Step 5 here: https://www.digitalcitizen.life/4-ways-boot-saf..., or using the command to unhide F8 Advanced Boot Options here: https://www.tenforums.com/tutorials/22455-enabl... where you can also try the old reliable Last Known Good Configuration.

4. From Safe Mode w/Networking work through the Windows 10 Install Integrity Checklist to make sure the install is set up correctly, optimized for best performance, and any needed repairs get done: http://answers.microsoft.com/en-us/windows/wiki....

Update your drivers from the PC's Support Downloads web page. Compare the latest drivers with the ones presently installed in Device Manager reached by right clicking the Start Menu. Make sure you have the latest BIOS, Chipset, Display (Video), Sound, USB3, Bluetooth, Network and all other drivers, or else download and install the latest now.

5. If Safe Mode doesn’t work or help stabilize things then return to Advanced Troubleshoot options. Next try Command Prompt to run through Windows 10 Install Integrity Checklist (above link) Step 10 repair commands including sfc /scannow, DISM, a full Disk Check: https://www.groovypost.com/howto/check-hard-dri..., or return to Troubleshoot options to Reset Your Windows 10 PC.
6. Better yet use the same booted media to do the vastly superior Clean Install following the steps in this link to delete all partitions down to Unallocated Space to get it cleanest: http://answers.microsoft.com/en-us/windows/wiki...
7. There is a step to Rescue Files from the booted media or Repair Mode Command Prompt first: http://answers.microsoft.com/en-us/windows/wiki...

These steps are excerpted from my tutorial that compiles everything possible for Troubleshooting Windows 10 Failure to Start: http://answers.microsoft.com/en-us/windows/wiki.... You can continue with the other steps there.

To test hardware, Dell and HP have onboard diagnostics triggered by powering up and pressing the F12 and ESC key respectively.

Test the RAM overnight to stress it with the best bootable test memtest86, following these steps which test both the sticks and the slots:

Test the hard drive with diagnostics:

Best is to use the manufacturer's own if there is one, otherwise use Seatools bootable long test: http://blog.nowherelan.com/2013/04/04/boot-seat...

I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.

If the hard drive doesn't show up anywhere in UEFI setup ( we know you have UEFI if it has CSM listed) including Boot Order Priority, then you need to get it recognized by changing the cable, reseating it, etc. until it shows up.

Test the hard drive or SSD with diagnostics:

https://mashtips.com/ssd-health-test-and-perfor...

HP and Dell have hardware diagnostics triggered by tapping the ESC or F12 keys respectively as you power on.

Best is to use the HDD/SSD manufacturer's own if there is one, otherwise use Seatools bootable long test: http://blog.nowherelan.com/2013/04/04/boot-seat...

Follow this up with a full Disk Check from the Command Prompt in Repair Mode or from bootable media: https://www.groovypost.com/howto/check-hard-dri... if necessary from the Command Prompt at boot: https://www.tenforums.com/tutorials/2294-advanc...

If you determine the hard drive is present and can even test it successfully, then try changing the CSM setting to enabled on the possibility you have Windows installed in Legacy Mode and something toggled of the CSM Setting that enables this in your firmware.

Try resetting the UEFI firmware to defaults, after taking note of the UEFI, CSM, Fast & Secure Boot and Boot Order Priority settings. For UEFI WIndows Boot Manager should be set first to boot. Reset to defaults here:

https://www.groovypost.com/howto/reset-pc-bios-...

If the hard drive is failing I'd replace it with an SSD which is the best upgrade you can give your PC - lightning fast, better than a new higher end PC without one.

Follow the included instructions or a video you find for your model via Google to swap it in and do this Clean Install which should get you past all difficulties as it has hundreds of thousands of others who have followed the steps in this link and never come back to report another problem: http://answers.microsoft.com/en-us/windows/wiki...
