A detailed guide to setting up different versions of BIOS to boot and install the operating system from a disk.

Navigation

In one of our previous articles, we talked about how to BIOS with various interfaces, put the boot from a USB flash drive to install the operating system from it. Today we will talk about how to return the settings BIOS back to original and install boot back with cd drive. It will be much easier to do this than setting up a computer to boot from a USB flash drive.

Although each version BIOS has its own unique interface, the basic principle of changing the settings of the boot device does not differ much in them. You will need to go to the main menu, go to a special section and install the CD-ROM in the first place in the list of devices connected to the computer. But first things first.

How to set boot from disk in BIOS?

  • Before proceeding directly to the setup BIOS, it will not be superfluous to figure out how to get into it. The entrance to this subsystem is carried out using a special key, which should be pressed almost immediately after turning on the computer.
  • As a rule, on a large number of desktop computers and laptops, buttons are assigned for this purpose. Delete" or " F2”, but other keys may also be used, depending on the model and version of the starter software installed. Therefore, carefully monitor the text prompts on the monitor while the PC is booting up.

  • Working with the BIOS interface is also carried out exclusively using the keyboard. The computer mouse and other controls do not work in it.
  • To navigate through the tabs, use the keyboard arrows " left/right" and " up down". To interact with the selected menu item, use the key " Enter” and in some cases the buttons “ Y" or " N". Use the button to return to the previous section. Escape».

How to configure Award Bios to boot from disk?

If you have pressed the login key BIOS and the same menu appeared on your monitor as in the picture below, then you are faced with Award Bios. It is found on a large number of motherboards.

To configure it to boot from disk, you need to follow a couple of easy steps:

Step 1.

  • Use the arrows to enter the category " Advanced BIOS Features", find and stand on the line " First boot device" and press " Enter» to display the additional menu.

Step 2.

  • In the pop-up window, you will need to select the device " CD-ROM» and press « Enter". You can assign a hard disk as the second device.

  • Next, exit to the initial menu using the button " Esc” and exit the BIOS, while saving the changes. To exit, stand on the line " Save & Exit Setup", press the "Enter" key, and after the Latin " Y» for the changes to take effect.

How to configure AMI Bios to boot from disk?

When during the login process BIOS a window with an interface will appear before your eyes, which is shown in the picture below, then we can conclude that a version is installed on your computer Bios AMI. It is also quite common on modern motherboards.

To configure this version to boot from disk, you need to follow a few simple steps:

Step 1.

  • Use the arrows to navigate to the " Boot” and further to “ Boot Device Priority».
  • You will see a small list of three lines. You need to be on the first line called " 1st boot device", press" Enter” and in the window that appears, select the device “ CD-ROM". The screenshot shows " DVD-RW».

  • As a result, the lines and the parameters given to them should look something like this.

Step 2.

  • Now you need to save the changes and exit with BIOS. With the key " Esc» return to the previous section, switch to the tab « exit”, select the line “ Exit & Save Changes”, press “ Enter” and in the window that appears, click “ OK».

  • After rebooting the PC, it will be possible to install operating systems from the CD.

How to set up Award Phoenix Bios to boot from disk?

And the last, less common BIOS version is Phonex Award. If at the entrance you see a similar interface, as in the picture below, then you have it installed.

To set the boot from disk settings in this version, follow a couple of simple steps:

Step 1.

  • As in the previous two options, you need to install the CD-ROM as the first boot device. Go to the section " Advanced" and stand on the line " First boot device».
  • Click " Enter” and in the list of devices that appears, select “ CD-ROM” or another device that replaces it.

Step 2.

  • The final step will again be to save the changes and complete the work with the BIOS. Go to the " exit”, stand on the line “ Save & Exit Setup”, press “ Enter" and confirm saving the settings with the Latin letter " Y».

  • This is the setting for all popular versions BIOS to boot from disk ends. However, in conclusion, you should be informed that in order to select a method for booting and installing the operating system, it is not at all necessary to resort to changing the settings in BIOS.
  • Most often, when you turn on the computer, you need to quickly press a certain button, which activates a special menu with a list of connected boot devices. Here you can quickly select CD-ROM, USB flash drive or hard drive to boot the operating system.
  • The button depends on the manufacturer of your PC. Most often, keys are assigned for this purpose. F1—F12.

VIDEO: BIOS setup to install Windows from a CD

Most often, in order to, the first thing you need to do is go into the BIOS and boot from the disk. So, let's talk about everything in order.

BIOS- This is a program that is built into a microcircuit on the motherboard. Thanks to this program, after turning on the computer for the first time, we are able to perform some settings, and most importantly, install the system.

So, in order to start working fully with a PC, you need to specify the BIOS from which device to boot, it can be a hard drive, flash drive or disk. In our case, it is necessary that in . That is why now we will look at how to enter the BIOS of our motherboard and make our computer boot from the disk.

How to enter the BIOS?

There is only one way to get into the BIOS. You need to turn on the computer and, without waiting for the system to boot, immediately start pressing one of the keys on the keyboard until we see the main BIOS window on the screen. And what is this key? On different motherboards, the key may differ, but most often it is the key: DEL, F2 or F11. I think you will stop at the DEL key, since it is she who is most often responsible for calling the BIOS.

By the way, the program we need looks like this:

Or maybe even like this:

Know it's the BIOS.

How to put boot from disk?

When we were in the BIOS, it's time put boot from disk. To do this, use the arrows and the "Enter" key to go to the Boot tab and open the Boot Device Priority menu.

Here you need to put CDROM in the first place.

AT BIOS boot from disk we set, now you can get out of here, not forgetting to save. This is usually done with the F10 key.

The BIOS itself may differ depending on the motherboard. For example, on my laptop it looks like this:

And on a new computer like this:

Everything is much easier here, you can work with the mouse and the interface is in Russian. By selecting the “Setting” menu on the left, I opened the settings in Russian. Here you need to go to the link "".

And in the menu that opens, put the CD / DVD disc in the first place in priority.

Having done these operations in the BIOS, you can insert a Windows disc or another program into the drive and the computer will boot from this device.

I hope I have given enough information to understand this issue, and you can easily put boot from disk in your BIOS.

Although the IDE mode is quite old, but without it, for example, the same Windows XP will not work, or you need to test the hard drive using various programs. Users are still asking the question of how to switch AHCI to IDE in BIOS.

What is AHCI and IDE?

Nevertheless, I decided to give a little terminology so that some users understand what's what.

IDE- as I said above, this is an outdated mode, physically it has a 40-pin connector and is intended for connecting hard drives, drives, and more. Most laptops and modern PCs no longer have an IDE, as do the switching properties in the BIOS. If your device has an IDE connector, then you need to switch to it only in the most extreme cases -.

AHCI- a modern standard that exceeds IDE in bandwidth several times. Works with SATA devices. If you need to choose between these two modes, then definitely AHCI fits this role much better. On a note, I want to say that if you purchase it, it will only work with AHCI, otherwise you can even forget about such a drive.

How to switch AHCI to IDE in BIOS

First you need to go into the BIOS, I will not describe how to do this here, because each laptop model is different. We read what to learn about entering the BIOS on your laptop model or motherboard.

When you get into the BIOS, you need to use the arrows to go to the tab "Advanced". Look for an option there called secure boot and move it to position Disable(Turned off).


There must be something like sata controller mode. If there is AHCI, then change to IDE or vice versa. If this section is not there, then try switching UEFI Boot into position CSM Boot.

On some laptops (particularly TOSHIBA), instead of IDE there may be an item Compatibility, which is a similar IDE.

In other laptops, like Acer in the BIOS, you can go to the tab Main and already there is an item sata mode, which you can switch to the desired position.

Modern computers, regardless of whether it is a desktop or a laptop, most have two video cards, integrated and discrete.

The integrated video card is soldered into the motherboard of your personal computer and uses part of the RAM for its work. The discrete one is connected as a separate component through various types of AGP, PCI connectors and has its own independent amount of memory that does not affect the operational one.


Often, both types of video cards are enabled by default, which can lead to conflicts and performance degradation, and when you have a powerful discrete video card, it makes no sense to load RAM with work, it is rarely superfluous.

Many users ask the question: how to switch the operation of the video card in the BIOS?

It all depends on whether you have a desktop computer or a laptop. Ask why? Problems can arise with portable computers and modular ones.

The bottom line is that discrete video in laptops is the same as integrated video soldered into the motherboard with a separate chip. And manufacturers decided to take care of ordinary users, and made automatic switching between video cards depending on the load on the system and graphics. And here this is the very case when it can play a disservice, since users do not have the opportunity to choose which card to work on.

But this is not a dogma, and not everyone has it, so we will still consider the options for how to switch the video card in the BIOS.
To do this, when you turn on the computer, we go into the BIOS (each manufacturer has its own combination when turning on the computer, common: F2, F10, F12, Del, Esc, Ctrl + Shift + Esc).

And then the little surprises begin. But don't worry just switching video, further may differ depending on manufacturer or BIOS version. Therefore, we will describe the logic of actions.

Let's find out what exactly we can do with video cards? Switch operation from integrated to discrete, increase the volume of integrated video and change the power frequency of the video card and connectors.

Depending on the BIOS firmware (BIOS), we need to select the section for setting up our motherboard, in most cases this is Advanced, or Main.

Further, if we have two video cards, we can choose which one to include, which to exclude. (Enabled - enable / Disabled - exclude). Or, from the drop-down list, immediately select which video card to use for work (PCI Slot, OnBoard, PCIEx, IGD, SG, Auto). You should pay attention, if you leave Auto, the system itself will determine when and which video card to turn on depending on the load.


Next, go to the Exit tab and select Save Change and Exit and click OK. It should be remembered that any changes in the BIOS (BIOS) can significantly affect the operation of your PC, so you should be very careful what and where you install.

Users may sometimes encounter a situation where the question of how to switch a video card or video accelerator in BIOS becomes urgent. A similar problem can occur not only because your video card is not working. The thing is that modern computers can have more than one video card, like their predecessors, but two at once - an integrated one and an external one. However, as a rule, only one of them can work at a time, and therefore it often becomes necessary to change the way video information is output to the monitor in such a way that it is carried out from another video card. To do this, you need to enable one of the video cards, and disable the other, respectively.

If you own a desktop computer, then you may have two video cards: one integrated into the motherboard, and the other installed in the motherboard expansion slot (sometimes such cards are called discrete). If you use a built-in (integrated) video card, and then purchased a discrete one, then you may encounter the following problem - how to disable the video card in BIOS and change the image output method so that it is carried out by a more powerful discrete card.

In most cases, there are no serious problems in the question of how to switch a video card in BIOS - the monitor will work with the video card to which it is connected. However, such switching in automatic mode is not always possible. In some BIOSes, the user must independently install the desired video card, and disable the unnecessary one. Often, BIOS options can be used to resolve this issue.

Therefore, it is worth talking a little more about how to enable a video card in BIOS. Usually this procedure is simple. The BIOS or options designed to enable the video accelerator may have different names. For example, these may be Primary Display options or in the section on setting up motherboard hardware. Possible values ​​for this option are Onboard, PCI, AGP, or PCI-E (depending on which buses are used on your motherboard). Selecting the PCI-E option, for example, will enable an external PCI-Express video card, and disable the built-in one.

Turning on the video card in the case of a laptop

Many modern laptops, like desktop computers, are equipped with two video cards - built-in and discrete. A laptop's integrated graphics card is usually located in the chipset or even in the processor itself. This video card usually has low power consumption, but at the same time, it cannot boast of high performance. Therefore, very often laptops are equipped with a second, discrete graphics card. Such a graphics card is much more suitable for graphics-intensive applications such as computer games.

It is easy to understand that due to the design of the laptop, in which the monitor is built into the case, the choice of the necessary video card cannot be done in the same way as in a desktop computer - by switching the cable. Therefore, this operation usually has to be performed by the user himself. True, there are laptop models that are able to automatically switch video cards depending on the load and applications used by the operating system, for example, turn on a discrete video card when a game starts and turn it off when a regular office application is launched. But if your laptop does not have such an opportunity, then often in order to use a discrete video card, the user has no choice but to disable the built-in video card in BIOS.

So, how to disable graphics card in laptop bios First of all, it is worth noting that it is far from always necessary to go into the BIOS to disable or enable the video card. The fact is that special software utilities are often used to switch the video card on laptops. If the laptop has an AMD chipset and a discrete ATI / AMD card, then switching can be done using the Catalyst Control Center program. To select a graphics card in laptops with an Intel processor and a discrete nVidia graphics card, you must use the nVidia Control Panel program.

If you are using a laptop with an Intel processor and a discrete ATI/AMD card, you will need to select the Switchable option in the Display Mode option in the BIOS to automatically switch the video card during operation. The BIOS Display Mode option will also be indispensable if you are running Windows XP, and not Vista, Windows 7 or 8, since software methods for controlling video accelerators usually do not work in XP. To enable the discrete graphics card of a Windows XP laptop, set the value of the Discrete option.

Conclusion

Enabling, disabling or switching the video card in a desktop computer is usually done automatically. In the same cases when switching the video card cannot be done automatically, as well as in the case of laptops, the user needs to use software tools or BIOS options. We hope that this article helped you figure out how to enable a video card in BIOS.
