All About Boot Sequence & How To Manage It

Most of the time we are just wondering about, What actually “Boot” is and why do we need to configure the Boot Order when every time we wanted to start something Bootable like Windows Setup, Some Bootable Utility Tool or maybe a Live Operating System.

So, Let’s See What It Is;

The word called “Booting” means ‘Startup’ mainly in technical language and you know, when every time you push the power button of your computer system, you just only short the circuit;




Which turn on the Power Supply and it starts the giving the power output to all of your computer or laptop’s hardware and then you’ll able to see the first logo screen of your PC and after some more couple of seconds, you’ll see that your Operating System will start to open.

Booting is the process which take place in the between the process of Powering On the computer and the loading of an Operating System, and it’s mainly done by Computer’s BIOS just to boot (or Start) the predefined Bootable Device;

And that’s the part where the Boot Sequence came in.

Boot Sequence is just a BIOS internal configuration which manages, to whom to boot first, or to boot last. And the best part is, you can also manage it on your own;

Which prevent your BIOS to Boot something randomly, and you can able to start to computer even without selecting the boot device when every time you starts your computer.




Normally, if your computer is working perfectly, then you really don’t need to take care of this computer setting, but in case, if you are having some problem with your OS, like some booting issue, or maybe you need to install the OS from your pendrive or maybe you need to run some bootable software by a Bootable CD, DVD, or USB;

Then this little setting is the one, who you can’t actually ignore (Cuz everything will boot according to this setting).

So, Now Let’s See How To Change/Manage The Boot Sequence;

If you’re going to make changes in the boot sequence of your BIOS, then the first thing you’ll need to do, is to get into your computer’s BIOS Setup.

And you know, getting into the setup can be tricky sometimes, because you’ll have to find that particular key, which you’ll need to press to get the direct access to your PC’s BIOS Setup.

And there is one more thing;

In case If you wanted to change the Boot Setting for the OS Installations purpose, like which only require to boot once and rest of all things will be done by the setup or maybe some other Bootable Utility Tool which only need to be one-time boot;

Then you know?

You can actually, quickly & directly, boot something like any Bootable Storage Device, whatever it’s your Pendrive or a CD, by just selecting that device in the boot menu of your computer BIOS. This will make your computer to boot that particular device just for only one time, which a lot of times will make thing easier for you. Given link below will help you to Know about that.

So, let’s back to the topic;

Step 1 – Entering In BIOS

In order to enter into your Computer’s BIOS, first, you’ll need to press a designated keyboard key (which most of the times you’ll see when every time you start’s your computer) and pressing that key will give you the direct access to the Bios setup page of your system. Just follow the steps given below:

  • Start your Computer System or laptop, or in case if it’s Power ON already, then you’ll need to shut it down, but in case if you can’t then you can also directly turned OFF your PC too and then turn it ON again.
  • Then you’ll need to take a look at PC’s First BIOS Logo and make your eyes to search for the default designated key.
  • The BIOS Entering key is predefined by the manufacturer and normally those are F1, F2 or a Del key. In case, if your monitor screen shows nothing besides the Manufactures’ Logo, then the best thing what now you can do, is to press the F-Keys from F1 to F12, one by one until you find the access.

And this is how a BIOS Setup Menu looks like:

Note 1 – All BIOS setup utilities are little different, so yours may look like this or it may be it’s possible that it will look completely different.
Note 2 – Some old Bios setup doesn’t support mouse input but it does, if you have a UEFI Bios in your motherboard or otherwise you’ll have to make changes by only using your computer’s keyboard.

Step 2 – Finding The Boot Setting

Now in your BIOS Menu, you’ll see lots of setting and information about your system, but in order to change the boot sequence, first, you’ll have to find ‘Boot Setting’ options.

Most of the times you will easily find this setting, but what if don’t? Then the other easy ways what you can do is to search the boot options under these particular setting tabs called;

“Advance Bios Features”, “Boot Setting”, “Boot Device Priority” Or “Bios Features” etc. And here are some examples of boot setting pathway shown in the image given below.

Step 3 – Change The Boot Order

To change the boot order, first, you’ll need to understand that what actually you’ll need to put the first boot device. I’m only saying this because if you saved your boot sequence incorrectly, then it’s quite possible that the bootable storage device what you wanted to get boot on your computer, will not boot at all.

This is how Boot Setting looks in BIOS Menu:

Now, the question is, what you actually need to do at this moment? So, the thing is, if you wanted to boot your pendrive to install the windows or maybe you need to boot something else bootable, then changing the “First boot device” or “Boot option #1” to the Removal Device can help you with that.

Or otherwise if you just wanted to make your computer to normally boot the device, then you’ll only need to change the “First boot device” to the hard drive of your, and that will help you with that;

And of course yes, you can give any storage device or optical drive, the first boot priority, so it can boot firstly when every time you starts your computers.

Some Bios will show a pop-up menu to select particular bootable device to designate the configuration, but in other hands, some of them allows you to move through menus by using the arrow keys, or maybe with the use of “+” and “–” keys to move the devices configuration location, up and down.

And just like I said, in the latest UEFI BIOS you can do this with the help of your computer’s mouse too.

When you’re finished with adjusting your settings, just save and exit in order to save every changes what you’ve made recently.

#What To Do, If You Having Some Problem While Booting Something;

  • If Your Flash Drive Isn’t Able To Boot – In that case, you’ll have to make sure that you made your flash drive bootable correctly or not. And for that, Click Here >> How To Make A Bootable USB Pen Drive?
  • Only For OLD COMPUTER Users – If your flash drive still isn’t able to boot, in that case, it’s also possible that your BIOS thinks that the pendrive is an external hard drive and because of that, sometimes you’ll need to put the hard drive on the first boot device priority and then change the flash drive setting in the BIOS’s other option named Hard Drive Priority, as shown in the picture given below:

  • If Hard Drive Or Optical Drive Not Found In BIOS – In that case, you’ll need to change the SATA/IDE cable of that drive which is not working. To Do that >> How To Change HDD, SSD and Optical Drive’s SATA Or IDE Cable?<< The laptop doesn’t use any SATA or IDE Cable. So, for laptop users who won’t find their hard drive or an Optical Drive, then you’ll need to install a new drive, which is not founded by the BIOS. And of Couse Yes, you can also try to use you faulty drive into some another laptop, just to find it’s definitely that drives fault or not.
