How to configure the fast boot (Fast Boot) of a PC in the BIOS

fast-boot-windows-10

When we restart the PC and pass the BIOS/UEFI POST, Windows you don’t have to load everything that is already saved in said file, just dump to RAM the previous state image of the OS from the hibernation file and places it at system boot, saving time on it and making everything much faster.

Logically, this differs from normal hibernation, where the entire configuration is saved and we pick up where we left off. This fact also differs in another point of the typical hibernation system that is more noticeable, for example, in laptops.

And it is that this Fast Boot on PC is not affected by the loss of system energy, that is, if the power goes out or we disconnect the PC from the power supply cable or even if we cut off the supply using the power button. it, Fast Boot will be enabled and will do its job correctly, which does not happen in hibernation mode.

Disadvantages of Fast Boot on PC

Like any technology, it has its drawbacks, since sometimes we will need to not have it active to perform certain tasks or functions. For example, there are programs that need a complete shutdown to take effect, and until recently some Windows updates required it. We see another similar scenario when we install a BIOS from Windows or update a firmware. In these cases the common shutdown is necessary and recommended.

Encryption systems also need a normal shutdown so as not to continually mount an encrypted older image, or for example, common shutdown will also be needed on systems that They do not have support for hibernation, where the problems can be quite large.

How to activate it in Windows

To activate Fast Boot with all its functionalities, you need two clear stepswhere the first one is to activate it in Windowsto later activate it in our BIOS or UEFIdepending on our motherboard and platform.

Starting with the activation in Windows, the first thing we need is to go to the control Panel of Windows and then go to the section of energy options.

Fast-Boot-1

Once inside we must click on «choose the behavior of the start/stop buttons» which is located at the top left of the window.

Fast-Boot-2

Once inside we will have to click on the button «change settings currently unavailable» to be able to access the options that we do not have available until that moment and that, as we can see, are visible in the lower section of the window, but not accessible.

Fast-Boot-3

Being already unlocked we will have to mark «enable fast startup (recommended)«, to later press the «save changes» button.

Fast-Boot-4

So far everything is simple and we would have already done the first part.

How to activate Fast Boot in the BIOS/UEFI of your PC

Let’s start with the second and perhaps somewhat more complicated part of this process. To do this we will have to restart the system and enter the BIOS / UEFI.

To achieve this, on its loading screen we will have to press one of these keys: DELETE, F2, F1, or F10 in some cases. On laptops, these keys may need to press the FN key at the same time as F2, F1 and F10, since otherwise the key that we press is not activated as such and we would have a laptop function that will vary between models and manufacturers.

In other words, you would have to press FN+F2 in the case of this last key or the corresponding one. This does not happen on PC because the function keys are just that, independent function keys.

Each motherboard and manufacturer uses one of these keys to enter, so if we don’t know which one it is, we will have to try or search for information about our equipment. Normally F2 or Delete is being standardized, but that’s been on motherboards for about 5 years now. We insist that if you can’t get into the BIOS/UEFI you look in the user manual how to do it, because it will be specific to the board or laptop.

Fast-Boot-5

Once inside we will have to leave or move to the section Boot or startupthis also differs on each plate and BIOS/UEFI.

Being already there, we will only have to enable said setting, where as a general rule some more options will be associated, where in principle we would not have to touch anything, since it must start correctly with the default settings. Once this is done, we will have to choose the corresponding boot diskeither our SSD or our HDD.

Fast-Boot-6

In our case it is a Corsair MP510, which as you can see is called «Windows BootManager«. Once this is done, we will press F10 to save changeswhere once we enter Windows again we can turn off our PC to see how the fast startup occurs as soon as we turn it on again.
