ATTENTION! The drive letters in the BIOS correspond to attached physical drives, not to individual partitions into which a drive is partitioned in MS-DOS or Windows operating systems. For example, if the system has two drives, the HDD connected to the Primary Master channel will always be referred to as C: in the BIOS, and the drive connected to any other channel as D:, despite the fact that in Windows it may have absolutely another designation.

One more example. When installing operating system to logical partition D: or E: first (or only) hard drive, to boot from it in the BIOS, you should specify the value C:, since the letters in the BIOS indicate physical disks, that is, the first (or only) drive will always be C:, even if it consists of several partitions (logical disks). In this case, the BIOS will transfer control of the master boot record (MBR - Master Boot Record), and that, in turn, will transfer control to the boot sector of the active partition.

The system can support several types of drives. In this regard, the Boot Sequence parameter can have different sets of values.

1. A, C, SCSI. With this value, the boot order will be as follows:

The system will first look for the floppy in the drive and, if successful, will boot from it. If the computer does not detect an operating system on the floppy disk, the process will stop with an appropriate message, for example: Non-system disk or disk error. Insert system disk and press any key when ready. In this case, you need to replace the floppy disk with a system one or remove it in order to boot from the hard disk;

When no diskette is found, the computer will attempt to boot from the first hard disk. If it doesn't have a boot sector or the disk itself, the system will move on to searching for SCSI devices;

With a SCSI controller connected, the system will attempt to boot using the SCSI device. If the device is not found, the installation will stop with the corresponding output.

2. C, A, SCSI. In this case, the computer will first try to boot from the hard drive, then from the floppy disk, and lastly from the SCSI device. Setting boot priority from the hard disk allows the system to normally boot Windows without wasting time accessing the disk drive.

4. C, CDROM, A. The search sequence will be as follows: HDD, cd drive, floppy drive. This option is suitable for normal booting the system from a hard disk.

5. CDROM, C, A. The first boot will be from the CD drive. This option is used to install an operating system from an installation CD. After that, you can return to the priority boot from the hard disk, so as not to waste time polling the drive every time you boot your computer.

6. D, A, SCSI. This option should only be used if the system has two hard drives and you want to boot from the second drive.

7. SCSI, A, C. This option applies if the operating system was installed on a hard drive with a SCSI interface. If it is not possible to boot from a SCSI device, the system will turn to a floppy disk or a regular IDE disk.

8. LS/ZIP, C. The system will boot from the SuperDisk (LS-120) or ZIP drive first. If there is no such media, the computer will attempt to boot from the hard drive. This option should only be used if you have one of the listed devices and need to boot from it.

Other combinations are possible in specific BIOS versions, such as A, C; A, SCSI, C; SCSI, C, A. In new BIOS versions, the Boot Sequence parameter is practically not found, and several separate parameters are used to set the boot order, which will be discussed later.

First Boot Device (1st Boot Device).

This setting specifies the media for booting the system first. If it is impossible to boot from this device, the computer will turn to those specified in the Second Boot Device and Third Boot Device parameters. The First/Second/Third Boot Device options are widely used over Boot Sequence because they provide more flexibility in choosing the boot order.

The values ​​of the First Boot Device parameter are the names of individual devices:

Floppy - disk drive;

HDD-0 (IDE-0) – hard drive connected to the Primary Master channel;

HDD-1 (IDE-1) – hard drive connected to the Primary Slave channel;

HDD-2 (IDE-2) – hard drive connected to the Secondary Master channel;

HDD-3 (IDE-3) – hard drive connected to the Secondary Slave channel;

CDROM (CD/DVD) - a CD-ROM drive connected to one of the IDE channels;

LS-120 - SuperDisk device (LS-120);

ZIP-100 - ZIP drive;

LS/ZIP - SuperDisk device (LS-120) or ZIP drive;

USB CDROM - CD-ROM drive with USB interface;

USB HDD - hard disk with USB interface;

USB-ZIP - ZIP drive with USB interface;

SCSI - device with SCSI interface;

Disabled (None) - There is no device to boot.

By selecting specific values ​​for the First/Second/Third Boot Device options, you can customize any desired boot sequence.

Recently, more and more common BIOS versions, where all boot devices are divided into several groups. In this case, the values ​​of the First/Second/Third Boot Device parameters can be as follows:

Disabled - no boot device is selected.

In some BIOS versions, only certain categories of devices, such as hard drives, are grouped into groups. In this case, in the list of values ​​of the parameter First Boot Device can be used as individual devices(from the list above) and their groups.

Recently, there are also BIOS versions where only those drives that were actually detected are present as the First Boot Device parameter values. If the device connected to the computer is not in the list of boot options, you should check its settings in the Integrated Peripherals section and other related sections.

Second Boot Device (2nd Boot Device), Third Boot Device (3rd Boot Device).

These parameters define the second and third device to boot the system; the values ​​will be the same as for the First Boot Device parameter. Sometimes you can also find a fourth boot device (although the need for it is extremely rare), denoted by the 4th Boot Device parameter.

Hard Disk Boot Priority, Hard Disk Drives.

Parameter Hard Disk Boot Priority, Hard Disk Drives (Fig. 6.6) determines the boot order from hard drives, if there are several. The values ​​can be a list of disks that are connected to this system board, and in some newer versions a list of actually detected disks.

Figure 6.6 - The window for setting the priority of hard drives

To select a priority device, set it first in the list as follows.

1. Highlight in the list desired drive using the cursor keys.

2. Press the "+" key on the optional digital block keyboard to move the device up in the list (using the key - respectively down).

Setting the device to the first in the list does not yet guarantee that it will be booted from it in the first place, since the order is determined by the First/Second/Third Boot Device parameters. So, to boot the system from a hard disk, you need to specify the value Hard Disk for the First Boot Device parameter.

Removable Device Priority, Removable Drives.

This option selects a removable media device to boot the computer. As possible values, a list of such devices supported by the system is used: Floppy, LS-120, ZIP-100, USB FDD, USB-ZIP, etc. In new BIOS versions, only those devices that are actually in the computer are available for selection.

This setting is used in the same way as the Hard Disk Boot Priority setting.

CDROM Boot Priority, CDROM Drives.

To boot the computer, the parameter sets the CD drive; used in the same way as Removable Device Priority and Hard Disk Boot Priority.

Boot Other Device, Try Other Boot Device.

The parameter allows booting from other devices that are not explicitly specified in the First/Second/Third Boot Device parameters. Possible values:

Disabled (No, Off) - only those devices that are explicitly selected in the First/Second/Third Boot Device parameters can be used for booting.

Boot From Network, Boot From LAN.

The parameter allows you to boot the computer using the local network, for which it must have a server that provides remote boot. This method has already lost its former popularity, and for ordinary computers, the function must be disabled so as not to slow down the process.

Possible values:

Enabled (On) – priority boot from a network device is enabled;

Here we are... BIOS... For some users, this abbreviation may be unfamiliar. And here they also talk about activating booting from a USB flash drive. The devil is not as scary as he is painted. So, first things first.

What is BIOS

On the motherboard of any personal computer or laptop there is a special memory chip that stores the BIOS. BIOS (Basic Input/Output System) stands for Basic Input/Output System. The BIOS must include a program initial setup computer ( SETUP), with which you can manage various system parameters of your computer, such as date, time, cooler rotation speed, device boot priorities...

Let's talk about device boot priorities in more detail.

What device is the BIOS trying to boot the computer from by default

Typically, the first boot device in a computer is the hard drive. But if we need to install an operating system on a computer, then we need to set the CD-ROM or Flash disk as the first boot device in the BIOS settings, depending on which media we plan to install the operating system from.

The trouble is that in order to install the first boot device, you need to enter SETUP program. To do this, after turning on the computer, you must press a certain key combination. What?

How to enter the BIOS to set up boot from a USB flash drive

The BIOS of different motherboard manufacturers have different key combinations for entering SETUP. Typically, this is either the " DEL" (most common on desktops) or " F2"(Most often happens with laptops). When you turn on the computer, the BIOS usually displays a hint about the need to press a particular key, for example, Press DEL to enter SETUP(Press the DEL key to enter the installer).

Well, if the hint on how to enter the installer does not appear or appears only for a moment, then you need to refer to the documentation for the motherboard. But do not rush to do it. It is usually sufficient to try keystrokes " F10" (manufacturer HP), " F1" (IBM and Phoenix manufacturers) or " Esc" (manufacturer Toshiba). Well, if these keys did not help, then use the official documentation of the manufacturer.

How to enable boot from flash drive in BIOS

We figured out the entrance to the installation program. Now you need to activate the download from USB Flash. And here we are again waiting for the same parsley: each manufacturer motherboard The installer menu is different. Therefore, further you will have to describe your actions for different manufacturers.

I note that over time you will learn how to intuitively activate boot priorities regardless of the manufacturer, since in the BIOS of any manufacturer you will find the same familiar device names: hard drive- HDD, CD-ROM- compact disc, Floppy or FDD- floppy disk reader Removable Devices- removable devices (removable disks and flash drives).

In the BIOS of some manufacturers, you will see priorities in the form of phrases First boot device(First boot device), Second boot device(second boot device), Third Boot Device(Third boot device), Boot Other Divice(Other boot devices), Hard Disk Boot Priority(Hard Disk Boot Priority), and third-party BIOSes will need to move device names from top to bottom, thereby increasing their boot priority.

Moving through the menu items in the BIOS is done using the cursor keys, the menu item is selected by pressing the key Enter. To move one level up (or back), use the key Esc. Saving the changes made to the settings is done by the command SAVE and EXIT SETUP(Save changes and exit the installer) in the menu exit or by pressing the " F10".

Attention! Before activating booting from a USB flash drive in the BIOS, insert this very USB flash drive into the USB port of the computer. The fact is that in the BIOS of some manufacturers, the flash drive is displayed in the menu item Hard Disk Priority as a separate hard drive only when it is physically connected to the computer.

Activating boot from a USB flash drive in the BIOS of different manufacturers

Phoenix BIOS Boot, then choose USB HDD and press the key F6 or move the device USB HDD up with keys -/+ . At the end press " F10

Award BIOS Advanced BIOS Features, then go to submenu Boot Sequence(Boot Seq & Floppy Setup) and choose as First boot device device USB HDD. At the end press " F10

Lenovo BIOS- in the menu you need to find the item Boot, then find the parameter Boot Priority Order and select device USB HDD, then press " F6" to make it the first one. At the end, press " F10" to exit the installer and save the changes.

HP BIOS- in the menu you need to find the item Advanced, then go to item Boot options, select device USB Hard Drive. At the end press " F10" to exit the installer and save the changes.

Dell BIOS- in the menu you need to find the item System, then go to item Boot Sequence and press Enter, then select a device USB Storage device, press the " U" to make the flash drive the first boot device. At the end, you need to exit the installer and save the changes.

Well, in conclusion, I inform you that it may turn out that the BIOS does not support booting from a USB flash drive (you simply do not find the USB HDD item). This can happen if the computer was bought five years ago. Decision in this case Most likely there will be a BIOS update. Updating the BIOS on modern ones is a simple process. So go to the manufacturer's website and look for an update to your BIOS version.

Read the article and still do not understand anything? In the article 05. Ubuntu installation: BIOS setup, disk partitioning, installation I described in detail in the pictures the BIOS setup for booting from a USB flash drive using the example of my computer.

That's all. Questions - in the comments.

Other identical option names:floppy drive Seek At Boot, Fast Boot, Floppy Check, Seek Floppy.

Among the BIOS options for managing drives, there are specialized options related to floppy drives. One such option is Boot up floppy seek. This option is designed to enable or disable the search for a drive while loading a personal computer, as well as its testing. It can take only two values ​​- Enabled (Enabled) or Disabled (Off).

As you know, the floppy disk drive is one of the oldest attributes of a personal computer. However, recently this element of the computer can rarely be seen in system units.

The BIOS Boot up floppy seek function is designed to search for a floppy drive, as well as initialize it. The initialization of a drive consists, in particular, in determining the characteristics of the floppy drive, for example, the number of tracks, etc. In addition, when the drive is initialized, its performance is checked.

In the event that the search and initialization of the device succeeds, the BIOS continues to boot the personal computer. In the same case, if the floppy drive is not found or configured incorrectly, then an error message is displayed on the monitor screen, but the computer continues to boot.

Should I enable the option?

The answer to this question depends on whether your personal computer floppy disk drive and what it is used for. It is worth noting that disabling the option in itself does not lead to the inoperability of the drive. Thus, if you set the value of the Disabled option, this does not mean that you will not be able to use the drive.

On the other hand, its initialization procedure takes some time during boot, usually a few seconds. Therefore, if it is important for you to speed up the download process by removing unnecessary elements from it, then you should set the value of the Disabled option.

All of the above applies to the case if the computer does not have a floppy drive. In this case, in addition to slowing down the download speed, the user will also receive an error message.

This error occurs, as a rule, on old computers on which a floppy drive was once used and still installed. For those who are not aware, a floppy drive is the device where magnetic floppy disks are inserted.

What does error mean floppy disk fail 40?

When you turn on your computer during the BIOS boot phase, if you see given error this means that there is a problem with the floppy drive. This may be a broken power cable or interface cable, a problem with the drive itself, or incorrect BIOS settings.

How to remove floppy disk fail 40?

In order to get rid of this error, you need to perform several steps. But keep in mind that after that your floppy drive will no longer be detected by the system and you will not be able to use floppy disks. (I don't know if there are people who still use them)

1. The first thing to do is disconnect the cable from the floppy drive. This applies to both the power cable and the interface cable. This must be done to eliminate the possibility of short circuiting possibly damaged loops. Do this only when the computer is turned off;
2. Next you need (one of the keys F2, F12, Delete);
3. Find there a line similar to Drive A, Floppy A. Usually located on the initial BIOS screen or in the “Standart Cmos Features” section
4. Change the value of this parameter to "None" or "Disabled"

How to fix floppy disk fail 40 error

Hello dear readers of the blog site. Why is it needed bios setting computer, before installing Windows. Let's say you want something install Windows XP operating system. You insert the installation disk with the operating system into DVD drive or paste flash drive, memory card. However Windows installation does not start, what do you do in such a situation? How do I get the installation to start? Of course, you need to change your Bios settings.

Set in the BIOS settings of the computer, the first boot device of your computer DVD drive or USB device in place of the hard drive.

In computers, this function is sometimes set by default and the DVD drive is the first boot device, then only the hard drive. After turning on, the computer first checks the DVD drive to see if there is an installation disc, then it just starts Windows boot from the hard drive.

However, in most cases, the hard drive is the first boot disk in the BIOS settings of the computer, so it is very important for us to know how to correct this subtlety in the BIOS settings of the computer.

And so let's start, first you need to go to Bios. In order to enter the Bios menu, you need to restart your computer. After the reboot, immediately start pressing a certain key. Basically if you don't have much old computer, this is the key: Delete, F1, F2, F10. But there may also be others such as: Ctrl+Alt+Esc or Ctrl+Alt+Delete or Esc.

And what key to enter the BIOS settings of the computer, you can find out in the instructions for your computer. After you enter Bios, you get to the main Bios window of the computer, in my computer it looks something like this:

Immediately I will make a reservation to understand all this, it will be necessary in English. Since Bios has never been, and is unlikely ever to be, will be in Russian. Appearance Bios and its functions on your computer may differ from the one in the photo. Therefore, it is desirable, of course, to understand a little English words, so as not to get confused. Do not forget, by going into the BIOS settings of the computer, you can forget about the mouse, you can manage the settings in Bios only using keyboard. , arrow up, down, left, right.

Well, we received a little information about the BIOS settings of the computer. Now using these keys, go to the Boot section (boot). Now we are in the boot section (Boot), it looks something like this:

In the Boot section, the first line is highlighted in white, it says "Boot Device Priority". If you translate this into Russian, it means "Priority of boot devices", then what we need. We press "Enter", and we get the following:

I will clarify that we went into the BIOS settings of the computer. We went to the boot section and chose the priority of boot devices.

Now change the value 1st boot device.

Of course, at first glance it looks like a meaningless set of words. But even if you look closely, it is easy to notice the differences. For example, in the picture you are looking at, the first boot disk is:

"FLOPPY DRIVE" is a floppy drive. That is, the computer will first try to boot from a floppy disk.

"HDD" is our hard drive. In our case, when the computer will not be able to boot from "FLOPPY DRIVE". It will try to boot from the hard disk, this does not suit us. If we want to start installing Windows.

"ATAPI CD-ROM" - This is, as everyone has already guessed, a CD drive. What we need for Windows startup. Let's put the CD drive in first place. To do this, by controlling the arrows, we make it so that the first device in the list is highlighted in white.

We press on "Enter". Then a small blue window will open.

Now in this small window, by controlling the arrows, we go down to the "ATAPI CD-ROM" option, press the "Enter" key on it. After that, the CD-drive should become the first boot drive. Next, return to the main Bios menu using the "Esc" key.

Well, now to the exit, using the "Arrow to the right" key, go to the "Exit" section. After making sure that the “Exit & Save” function is highlighted, which means “Save and Exit” in translation, press “Enter”.

After that, a confirmation window will open, confirm by clicking on "OK" or some "Y".

All computer bios setup completed. Congratulations! You have passed the most difficult stage for novice users when installing Windows.

Good luck in installing the operating system and see you on the pages of the blog site.

Tip: never run files (any - neither exe, nor doc, none!) from a floppy disk under Windows!

Gennady Pal:
I apologize to the author. Many advisers (including myself) suffer from a little arrogance. I looked in the BIOS, how can I do "DISABLED-disable" FDD drive. I have BIOS AWARD. Entered the Standard CMOS Award Features. Found Drive A. Chose - 1.44, 720, etc. - NONE. Drive B has been NONE for a long time. When you exit the VIOS - Save & Exit Setup -> Y. I wish you success in mastering the computer. Need some reading and feel free to ask. People will always help.

Yuri Alexandrovich Peisakhovich:
In BIOS, disable the option "Floppy boot seek" or similar.

Gennady Pal:
Do you have any special computer? About BIOS there is information in the description of the computer. True, there, as in a computer, everything is in English. I'll have to learn the language a little.

Gennady Pal:
The "Floppy boot seek" option is active only at the moment of switching on, when the BIOS is testing. This disadvantage appears when installing some low-quality programs. It's best to disable floppy drives in BIOS. But the fact that “When the floppy drive is turned off, the OS terribly slows down and loads for a very long time” - there may be another reason.

This is a question from the archives. Adding responses is disabled.
