Boot the system from cd. How to boot a computer from disk.

Setting the computer to boot from DVD or CD is one of those things that may be required in the most different situations, first of all, in order to install Windows or another operating system, use the disk to reanimate the system or remove viruses, as well as to perform other tasks.

Relatively speaking, booting from disk is usually somewhat easier and there are fewer nuances in this operation than with using USB USB flash drive as a bootable drive. However, enough ranting, to the point.

Login to BIOS to change the order of boot devices

The first thing that needs to be done is to enter the BIOS of the computer. It was quite a simple task until quite recently, but today, when UEFI came to replace the usual Award and Phoenix BIOS, almost everyone has laptops, and various hardware and software Fast-boot technologies are actively used here and there, go to BIOS in order to put boot from disk is not always an easy task.

In general terms, the entrance to the BIOS looks like this:

In some cases, which is especially common on modern laptops, you will not see any inscription: it will start immediately Windows boot 8 or Windows 7. This is due to the fact that they just use different technologies for quick launch... In this case, to enter the BIOS, you can use different ways: Read the manufacturer's instructions and disable Fast Boot or whatever. But, almost always one simple way works:

Turn off your laptop
Press and hold the F2 key (the most common key to enter BIOS on laptops, H2O BIOS)
Turn on the power without releasing F2, wait for the BIOS interface to appear.

This usually works.

Setting boot from disk in BIOS of different versions

After you hit the same BIOS settings, you can set the boot from the desired drive, in our case - from boot disk... I will show you several options at once on how to do this, depending on the various options for the configuration utility interface.

In the Phoenix AwardBIOS BIOS version most common on desktop computers, select Advanced BIOS Features in the main menu.

After that, select the First field Boot Device(first boot device), press Enter and select the CD-ROM or device that matches your disc drive. Then press Esc to exit to the main menu, select “Save & Exit Setup”, confirm saving. The computer will then reboot using the disk as a boot device.

In some cases, you will not find either the Advanced BIOS Features item itself, or the boot parameter settings in it. In this case, pay attention to the tabs at the top - you need to go to the Boot tab and put the boot from the disk there, and then save the settings in the same way as in the previous case.

In modern UEFI interfaces BIOS setup the loading order may look different. In the first case, you need to go to the Boot tab, select the drive for reading disks (Usually, ATAPI) as the First Boot Option, then save the settings.

In the version of the interface shown in the picture, you can simply drag the device icons to indicate the disk as the first drive from which the system will boot when the computer starts.

I have not described everything possible options, but I am sure that the information provided will be enough to cope with the task in other BIOS versions - booting from disk is set approximately the same everywhere. By the way, in some cases, when you turn on the computer, in addition to entering the settings, you can call the boot menu with a specific key, this allows you to boot from the disk once, and, for example, for Windows installations It's enough.

By the way, if you have already done the above, but the computer still does not boot from the disc, make sure that you burned it correctly.

Operating systems accumulate over time unnecessary files, parts remote programs... There is a need to reinstall Windows or another OS. Most modern laptops (and sometimes stationary computers) no longer have a CD-rom, so you need to know how to run bootable USB drive through BIOS, set the launch priority.

Configuring BIOS for booting from a USB flash drive

Every modern PC user should know how to install a boot from a USB flash drive in BIOS. This is due to the phasing out of disks and the ease of use of removable drives. It is much easier to copy the distribution kit (installer) of the system to the media and install from it. The only difficulty faced by everyone who decided to install an OS from a drive is correct setting BIOS. In it, you should change the boot priority, which will force the computer to first read data from removable media, and only then run files from hard disk.

Some PC owners are faced with the problem that Bios does not see the bootable USB flash drive. To avoid this situation, you should follow these recommendations:

The drive must be in USB before starting the PC.
Please connect the media to the 2.0 connector because 7th version The OS does not have drivers for 3.0 input.
Sometimes there is no boot from a USB flash drive in BIOS just because the USB controller is turned off (Award version). It must be enabled from the Integrated Peripherals / Advanced Chipset Features section. Make sure that the word Enabled is next to this line.

Booting from USB to Award Bios

Global laptop manufacturers (Lenovo, Asus, Sony, HP) can install different versions BIOS to their devices. Below is an example of how to load the Award version from a USB flash drive in BIOS:

Restart your computer, press Del or F2 until you see blue screen.
Go to Advanced BIOS Features.
If the option called First Boot Device is immediately present, then you should click on it and switch to removable media with the OS.
In new versions of the system firmware, there is an additional menu section called Boot Seq & Floppy Setup. Within it, set the drive back as First Boot Device.
It is desirable to set the second device to your HDD... This will be needed during the installation process so that it does not start in a circle.
Use the Esc key to go to the main menu, go to Save & Exit Setup. Confirm saving the changes.

How to boot from a USB flash drive into AMI BIOS

Do not forget that the bootable media must be inserted into the slot beforehand. Below is an instruction on how to install a boot from a USB flash drive in AMI BIOS:

go to settings using the Del button (press during the initial splash screen until BIOS appears);
using the arrows, you need to select the Boot section;
go to the Hard Disk Drives menu, then press enter on the 1st Drive line;
select the name of your drive with OS from the list, press Enter.
go to the Boot device priority section;
enter the First boot device menu by pressing Enter;
expose removable media again;
go to the top menu, select Exit saving changes or Save changes and exit, confirm consent to make changes.

How to install a boot from a USB flash drive in Phoenix-Award Bios

There is another version of the global settings. Below is an option on how to install a boot from a USB flash drive in Phoenix BIOS. This option is much less common, but the principle remains the same: you must assign a boot priority so that the program launches the OS installer. To go to the settings, press Del or F2, then:

Check if included USB port... Go to Peripherals and the word “Enabled” must be in front of the “USB 2.0 Controller” line.
After that, go to the Advanced tab, there, opposite the “First Boot Device” line, set the USB-HDD value.
Exit the settings with saving via Save & Exit Setup.

How to boot Windows from a USB flash drive to EFI (UEFI) Bios

Latest Versions Windows offers the easiest and most intuitive way to boot from a USB flash drive in BIOS. If in previous firmware the menu looked like a regular list, in which it was necessary to use the arrows on the keyboard for manipulation, the new UEFI interface includes graphic elements, supports the use of the mouse. For different models for laptops, the transition occurs using special buttons, for example:

HP - ESC first, then F10;
Asus - Del, then F2.

Some Windows users 8 note that they are having problems migrating to BIOS version of UEFI. To solve this problem, use one of the following options:

Go to PC settings through the control panel, select the section with power settings. Here you need to turn off Fast Boot Mode.
Restart your computer and press the buttons indicated on the start screen to go to the BIOS.
Press Shift + Restart to restart Win 8. In the menu after reboot, select the Troubleshoot section. Go to “Advanced options”. Here you need to click UEFI Firmware Settings: you will be redirected to UEFI immediately after restarting your PC.

There are two ways to start from a drive through a new BIOS. Do not forget that after reinstalling the OS, the boot priority settings will need to be reset to their original form (so that the hard drive boots first). Graphic global settings are very clear, any user can navigate the sections. There are two simple options for prioritizing a drive:

Go to the Boot Priority menu, it is located at the bottom of the screen. Drag the image of the removable storage device to the first position instead of the hard disk and release.
Click on the Exit / Advanced mode button, confirm your consent to go to advanced settings. Here everything is done according to the previous scheme: you need to click in the Boot section on the Boot Option Priorities item. In the Boot Option # 1 line, select your removable drive. Save and exit settings.

Very often the computers of individual users stop working properly. And then people start wondering how to load the system. It is to this question that we will look for the answer in this article. In fact, there are several ways to download. We'll look at three of them. These are booting from disk, from a flash drive, and booting in safe mode.

Booting from CD-DVD

Often there is a situation in which it is necessary to boot from disk, for example, during the installation of Windows, or loading other applications right at startup. For such a download, you need to go into the BIOS and delve into its settings. You can have an Award or an Ami BIOS. So, loading into Award BIOS.

run BIOS settings by pressing the Delete key while your computer is starting up.
use the arrows on the keyboard to select the "Advanced BIOS features" tab and press Enter.
in the same way, select the "First Boot device" tab, and then, in the window that appears, using the same arrows, set the pointer to the CDROM label.
exit the BIOS, saving the settings (F10 key).

After the red window appears, press Enter. The computer will reboot from the disk. Now let's look at an example boot into Ami BIOS.

start the BIOS.
use the arrows on the keyboard to select the "Boot Device Priority" tab and press Enter
select 1st Boot Device. In the window that appears, select the CD-DVD drive, confirm your choice by pressing Enter.
exit the BIOS, saving the settings (F10 key).

So, we figured out how to boot the system from disk, now let's move on to other boot methods.

Boot in Safe Mode

First, let's figure out what Safe Mode means and why you need it. Firstly, this is one of the boot methods, if the usual one does not work. Secondly, if you delve into the concept, then I must say that Safe Mode (safe mode) is a diagnostic mode. It is also called crash protection mode, as it makes it possible to find problems that are caused by wrong work hardware and software of the computer. In this mode, Windows applies the default settings. If you have installed new programs and the computer does not boot, try starting in Safe Mode... The cause of the breakdown may be installed drivers, then they need to be removed. How do I boot the operating system in Safe Mode? Here's the instruction:

first, restart your computer;
during the restart press the F8 key. If the Boot Device window appears, you need to select the hard drive on which the system is located and press Enter, and then F8;
you will see a menu of additional boot options, use the arrows on the keyboard to select "Safe Mode";
select an account;
in the "Desktop" window with a message that the OS is running in Safe Mode, click "Yes".
after loading the desktop, you will be able to work on your computer.

Booting from a USB stick

Sometimes there are situations in which it is important to know how to boot the system from a USB flash drive. For example, a CD drive does not read discs well, and you need reanimation or reinstallation operating system... The OS can be loaded from a flash drive, but only if it is working properly and correctly compiled. So, insert the USB flash drive into your computer and only then turn it on.

After turning on the computer, look at the screen, in its lower left part it is written which key you need to press to get to the "boot device", usually Esc or F12.
Next, you will see a menu for selecting those devices from which your computer can be started. Select your flash drive in the list and press F12 (hold it until your system unit will not emit a special signal - a squeak).
The Boot Menu will open in front of you. Here, using the arrows on the keyboard, you select "Hard Disk" and press the Enter key.
In the "Hard Disk" menu, choose your USB flash drive. After pressing Enter, the computer starts booting.

But remember that all subsequent times the operating system will boot from the hard disk, not from the drive.

For many situations associated with the use of modern computers, intervention is required, so to speak. basic settings computer hardware. Therefore, it is advisable to know how to do it correctly.

Probably, in the recent past, each of the users had to spend a "nth" amount of money in order to reinstall the operating system and the necessary software applications... Waiting for a specialist and some inconveniences associated with the call still force a person to draw the proper conclusions and decide on an extremely expedient step - to carry out the process of reinstalling an inoperative OS with his own hands. As a result of this, the first quite natural question appears: "How to put boot from disk in BIOS?" It turns out it's not that difficult.

So, what exactly is a BIOS?

The fact is that any computer is initially equipped with an independent electronic chip, the essence of which is to control the hardware of the computer. That is, a person using functionality BIOS, in practice, can make changes to its software settings, which is critically reflected in the OS boot parameters. Activation or deactivation of some hardware components is also performed in the environment of the basic I / O system. At its core, the question of how to put boot from disk in BIOS implies changing the priority of one of the boot devices.

To date, 3 types of BIOS are widely used:

American Megatrends (AMI).
Award Software (Phoenix Technologies).
(UEFI).

The last item on the list is the new brainchild of Intel. Practical, multi-layered and with an intelligently understandable interface, the revolutionary BIOS has bypassed its predecessors in the perfection of technological solutions.

The question of how to put boot from disk in BIOS is solved in different ways

In order to enter the basic computer system, you first need to know its “pedigree”, that is, what type your BSVV belongs to. The moment you turn on your desktop or laptop, from the information displayed in the upper left corner of your monitor, you can understand what you have to deal with. Well, and what to do next, you will learn from what you read below.

Award Software and Phoenix Technologies

All the same key "delete" and "morse-like" pressing will allow you to enter the holy of holies of your electronic machine.

Use the up / down arrows to navigate to Advanced BIOS Features.
In the first paragraph (usually by default there is Floppy), use the "enter" button to call the drop-down submenu and specify "CD-ROM", this is your drive, which has become the priority bootloader.
We return to the main menu by pressing "esc".
Save & Exit Setup is the next step, so to speak, the final one. Agree to the question of saving by choosing the letter "Y".

Attention! Booting a laptop from a disk differs from the stationary version only in some difference in the buttons used to enter the basic laptop system. It is most likely to use the "delete" and "F2" keys. Again, you will have no problem with the correct button function if you press "Pause" during the initial boot of the computer. The service line is displayed at the bottom of the display with detailed information about which key is responsible for the direct entry into the BIOS settings.

Press "F10" to change the sequence of the startup devices at the time of reboot. In some models it is necessary to use the "F2" or "F6" button.
Select the "Advanced" tab, right / left navigation arrows will help you with this.
Then in the "Boot order" set the boot priority - DVD drive.
In conclusion, press "F10" and confirm your consent to the changes.

It is worth noting that the "F9" key allows you to return to the default values. Now for you, the question of how to put boot from disk on an HP laptop is also permissible and understandable.

American Megatrends (AMI)

When starting the computer, shortly press the "delete" key. In the appeared BIOS interface, select the "Boot" menu.
Then - "Boot Device Priority".
In we note the priority of booting from a CD-DVD drive, and the hard disk should be (visually) lower.
Next step: press the "esc" key.
Go to the "Exit" menu and use the up / down arrows to activate "Exit & Save Changes".
In the drop-down box, agree by clicking "ok".

Congratulations! The question of how to put boot from disk in BIOS is solved for AMI BIOS.

Extensible Firmware Interface (UEFI)

This basic system is much clearer and more comfortable to use. Firstly, the Russian language is provided in the design of the interface. Secondly, everything is extremely thought out. An important convenience can be considered the realized possibility of control with the help of the mouse. So, we configure the required boot parameters:

And again the irreplaceable key "delete". A few clicks will help us enter the main BIOS (UEFI) window.
In the lower left corner of the screen, select the highlighted interactive button "More (F7)". Click it with the right mouse button.
A drop-down window will ask you to confirm your actions: "Enter advanced mode?" Agree - "ok".
Next, you need to activate the "Download" tab.
Scroll with the mouse scroll the proposed list to the last item "Loading changes".
Next step: right click select your drive from the first suggested drop-down list. After that, the base system will automatically reboot the computer with the changed parameters.

Agree, everything is elementary and simple. After you have changed the priority of the devices in the BIOS program, booting from the hard disk will only occur if there is no installation disk... However, after all the necessary steps, it is recommended to return the boot priority to the default values.

Finally

Before your theory turns into lawful practice, it is worth remembering one golden rule: if you are not sure of the correctness of your actions, you should not change the settings in the basic BIOS system. The consequences can be dire. Remember: by making adjustments to the control program of the computer's hardware environment, you can completely "kill" the machine. Therefore, be attentive to what you are doing.

Be especially careful when adjusting settings that affect the supply of voltage to devices. It is also not recommended for users who have an initial understanding of the operation of a computer to independently perform actions that contribute to overclocking the processor, or to reflash the BIOS software, otherwise you will not end up with problems.

Each user remembers about BIOS (Basic Input / Output System) only when it is necessary to reinstall the operating system from the disk. The key combination that brings up the start menu with the necessary options for each laptop depends on the model motherboard laptop... When booting, the system displays a prompt for a certain combination, for example, for HP laptops, this is the "Esc" button - "Press the Esc key for Startup Menu".

One of the largest manufacturers information technologies in the world, Hewlett-Packard took care not only of a smooth entry into the start menu to reset boot parameters, but also developed two options for changing the setting: without entering the BIOS and directly in the BIOS environment. You can select the required item in the start menu:

"F-1" - system information,
"F-2" - system diagnostics,
"F-9" - change boot settings,
"F-10" - BIOS,
"F-11" - restore the factory settings of the laptop.

Item "F-9" allows you to change the boot settings without using the BIOS menu. Selecting this item gives you a choice between a CD / DVD disc or an HP notebook hard drive. Navigation is carried out using the cursor keys, that is, the up and down arrows. The selected option is activated by pressing the "F-10" key, which confirms the changes in the settings and, when a CD / DVD disc with the operating system is inserted into the drive, it starts loading it.

Item "F-10" opens the BIOS environment for changing the parameters. Navigation is also carried out by the cursor control keyboard. The name of the current section or subsection is displayed in the upper part of the window. To change the settings, you need the "System Configuration" section. In the menu that opens, the section "Boot Options" is responsible for the changes, which provides a list of possible sources for loading data. If any value from this list is activated, then opposite it in quotes is the value "Enabled", if not, then "Disabled". We activate "CD-ROM Boot" accordingly. Below the list possible activations there is an option "Boot Order", which must be entered to change the order of boot places. The list by default is headed by the laptop's hard drive, to change the list by pressing the "F6" key, move the "CD / DVD ROM" up to the first position. To exit to the main BIOS menu after the necessary changes, use the "Esc" key. To save the changes, you need to confirm them when exiting the BIOS.

If in both cases, when changing the parameters, the boot from the selected CD / DVD disc is not performed, then you must make sure that the disc is multiboot, in the absence of defects and damage to the disc. You can use Nero Express 6 to create a multiboot disc with an operating system such as Windows XP.

After restarting your HP notebook, the operating system will boot from the floppy drive. After installing the system, you will need to go into the BIOS again and return the boot settings from the hard drive.
