BIOS Update Information
If a Dell computer is unable to boot into the Operating System (OS), the BIOS update can be initiated using the F12 One Time Boot menu. Most Dell computers manufactured after 2012 have this function and you can confirm by booting the computer to the F12 One Time Boot menu.
When a computer is starting up, the user can access the Boot Menu by pressing one of several keyboard keys. Common keys for accessing the Boot Menu are Esc, F2, F10, or F12, depending on the computer or motherboard manufacturer. The key to press is usually specified on the computer's startup screen.

Use this option to control whether you can press the F11 key to boot directly to the One-Time Boot Menu during the current boot. This option does not modify the normal boot order settings.
From the System Utilities screen, select System Configuration > BIOS/Platform Configuration (RBSU) > Server Security > One-Time Boot Menu (F11 Prompt) and press Enter. Select a setting and press Enter. Press F10.
F11 is a special key set by HP, Dell, or Lenovo computer manufacturer to recover system to computer default settings when your computer (PCs, notebooks, desktops) corrupted due to hardware or software failure.
After locating your computer's power button, press it to power on your computer. Your PC will now boot into the BIOS (Basic Input Output System) part. This is the part of the boot process that tells your computer what it should do. E.G, boot windows, give a keyboard error, turn off the PC for overheating, etc.
While the display is blank, press the f10 key to enter the BIOS settings menu. The BIOS settings menu is accessible by pressing the f2 or f6 key on some computers. After opening the BIOS, go to the boot settings.

The "F12 Boot Menu" must be enabled in BIOS. It is disabled by default.
Your boot sequence should be set to how you want the computer to boot.

If you're trying to fix a computer or reinstall its operating system, you may need to change the boot sequence.
On the Install Windows screen, select Next > Repair your computer. On the Choose an option screen, select Troubleshoot. On the Advanced options screen, select Startup Repair. After Startup Repair, select Shutdown, then turn on your PC to see if Windows can boot properly.
