This write up will deal with Computers with Windows 10 systems using the old BIOS, the new UEFI and how to install, troubleshoot and diagnose issues on day to day problems and installs. It will help you understand how and when to use these settings and configurations.

We have come to a new time in Computing life and now we find that just knowing how to turn on a computer is not enough to get us through our day to day computer tasks. Then comes Windows 10 which is Microsoft’s latest Operating System and is going to be with us at least 10 years.

To start with I will let you know how I plan to walk you through this new way of thinking when it comes to Computers, Software and of course Windows 10.

This will be a multi-release Blog. Other topics from this kick-off Blog will follow.

I will first start with computers, and answering your BIOS vs UEFI questions. Please note this blog is for the computer beginners and novice. For those who feel they are past the basics you still may find some insight through this blog and may fill in some gaps you have in the way Computers and how Windows 10 works together with the hardware.

Lets get on the same page on what we call the Hardware and Software components that make up a computer.

  THE BASICS

Hardware – This refers to the Mother Board and all the supporting equipment and devices that require the computer to work.

BIOS – “Basic Input/Output System”  located in the “Chip-Set” of the Motherboard. This is the older way to boot up.

UEFI – “Unified Extensible Firmware Interface” it replaces the “BIOS” system but most systems give you a choice of which one you can use. Please note there are some requirements for how your Hard Drive is formatted depending on which one of the choices you use. We will get more into that in the next segment of this Blog.

We will start with Computers in general – Some questions answered here are:

What types of computer systems that work with Windows 10 are out there ?

What is the difference between the Motherboard and Operating System, (i.e. Windows 10) 32 bit and 64 bit ?

What is the difference between a 32 bit and 64 bit  Motherboard BIOS/UEFI Firmware and CPU ?

BIOS info –

There are many components in a computer and one of them is called the Board BIOS chip.

This Chip is build into the Mother board and can not be changed out. It is what we call the “Chip Set”. The “Chip Sets” starting around 2004 all boards now come with a 64 bit “Chip Set”.  You don’t have to worry about the “Chip Set” anymore.

When a computer is booting up it goes through a POST meaning it goes through a “Power On Self Test” and it initializes system devices such as the CPU, RAM, Interrupts and DMA controllers and other parts of the chipset like the Video Display, keyboard, Mouse, Hard Drive and other basic hardware.

This is before it even sees what kind of Operating System you have. If it fails the “POST” test it’s not your OS that the issue. Most computers have a beep tone sequence. You can get the beep tone sequence meaning from the Mother Boards Vendor Website.

Steps to change a BIOS booting computer into a UEFI Firmware Booting computer.

The three steps have to be made in the correct order or else you will get messages saying the change cannot be made. The easy way to remember it is that the changes are made bottom to top.

First get into your BIOS – F10 for HP and for Dell F12.

To get to your UEFI Firmware boot up you have a few options depending on what kind of computer you have. If you can get to your OS go to the

1.)  The first change is to disable Secure Boot. It has its own entry on the left side. Under Secure Boot Enable, switch the option to Disabled and hit Apply.

2.) The second change is under General and Advanced Boot Options. Check the box to ‘Enable Legacy Option ROMs’ and hit the Apply button.

3.) The last change is also under General but in the Boot Sequence section. Switch the Boot List option from UEFI to Legacy and then hit Apply.

UEFI Secure Boot: In Bios, disabled secure boot & enabled Legacy ROMs.

NOTE:  You must Disable the Secure Boot first, then go back to Enable Legacy ROMs

This will let you boot from a USB or CDROM.
