(system boot sequence). The polling sequence is determined various drives to load the operating system. These devices are designated either by letters for physical hard drives and regular disk drives, or the device name, such as "CDROM" for CD-ROM drives. LS-120, Iomega ZIP, ATAPI CD-ROM, IDE and SCSI drives are supported. Can take values:
"A,C" - this choice is justified only for the case of booting from a floppy disk and is found in older PC models,
"A,C,SCSI"
"C only"
"D,A,SCSI" (intended when using at least two IDE hard drives),
"E,A,SCSI" (similar for 3 disks),
"F,A,SCSI" (similar for 4 disks),
In some BIOS versions the option "Boot Sequence" transformed into several independent options, naturally with greater selection and flexibility. It looks like this, for example, for "AMI BIOS":
The parameters can take the following values: "Floppy", "HDD-0", "HDD-1", "HDD-2", "HDD-3", "LAN" (or "Network"), "SCSI", "LS /ZIP", "CD-ROM", "Enable", "Disabled". Of course, not all listed devices can be primary boot; the entire list of devices for all four options is listed.
And one of the “AMI BIOS” options contains the same options, but with the values “Floppy”, “Floptical” (RS 120), “CD ROM”, “SCSI Device”, “Network”, “IDE0”, “IDE1”, "IDE2" and the option "Try Other Boot Devices" through the value "Yes" it makes it possible to additionally select a boot option if the available options do not suit the user.
A more modern version of "AMI BIOS" looks quite unusual: "Disabled", "1st IDE-HDD", "2nd IDE-HDD", "3rd IDE-HDD", "4th IDE-HDD", "Floppy", "ARMD- FDD", "ARMD-HDD", "ATAPI CDROM", "SCSI" (only as the first or second boot device), "NETWORK" and "I2O" (the last two parameters only as the first boot device). For more information about ARMD (ATAPI Removable Media Disks), see the "Peripherals & Resources" section.
A very unusual boot option at one time offered "Phoenix BIOS" with the option "System Load " . The option had two parameters:
"Standard" - the OS could be loaded (by default) either from a floppy or from hard drive,
"Diskette Lock" - only from the hard drive. It is clear that this was a long time ago.
Additionally, see the option below "HDD Sequence SCSI/IDE First".
It is also necessary to note the following. All of the listed options do not cover all possible loading nuances offered different versions BIOS. Therefore, the user must always be prepared to meet a non-standard situation.
Other parameters identical in purpose: Boot device select, Boot drive order, etc.
The Boot Sequence option is designed to select devices from which the PC will boot. Option values may vary depending on the BIOS version and the drives installed in the computer.
As you know, a computer without an operating system installed on it is just a useless pile of metal and microcircuits. An operating system (or several operating systems) can be located on some storage medium - for example, on a hard, optical or floppy disk, or on a flash drive. To select the one you need operating system, The BIOS must determine which of the drives installed in the computer will be considered bootable.
However, in practice, the operating system is not recorded on every medium. Therefore, the BIOS has to go through all the installed media until it finds the media from which it can boot.
The Boot Sequence option is intended to determine the order in which media will be sorted. Typically, its values are all media installed on the system. The user can set his own for each media serial number, corresponding to its priority when searching for BIOS boot entry.
In some cases, there is no single Boot sequence option in the BIOS, and instead the user can install the device in several options, such as, Second Boot Device, etc. Also, sometimes physical disks may not be in the list of options, and the user can choose instead logical drives– A, B, C, D, etc. In this case, the letters A and B stand for floppy drives, and the subsequent letters stand for .
Which parameter value should I choose?
It is difficult to give a definite recommendation in this regard, since everything depends on the habits and intentions of the user, the type of operating system used and the purpose of the computer. In most cases, if you boot the OS from a hard drive as standard, you can install it as the primary boot device HDD. However, if for some reason you do not want to boot from the hard drive, but want to boot from removable media, then you can install this drive as the first boot device.
ATTENTION! The letter designations in the BIOS correspond to the connected physical disks, and not to the individual partitions into which the disk is divided in operating systems MS-DOS systems or Windows. For example, if there are two drives in the system, the HDD connected to the Primary Master channel will always be designated as C: in the BIOS, and the disk connected to any other channel will be designated as D:, despite the fact that in Windows it may have no another designation.
One more example. When installing the operating system in the logical partition D: or E: of the 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 is always will be C:, even if it consists of several sections ( logical drives). In this case, the BIOS will transfer control of the Master Boot Record (MBR), which 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 loading order will be as follows:
First, the system will look for a floppy disk 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 and display a corresponding 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 to boot from the hard drive;
When the floppy disk is not detected, the computer will try to boot from the first hard drive. If there is no boot sector on it or there is no disk itself, the system will proceed to search 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 terminate with an appropriate 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 the hard drive to boot first allows the system to booting Windows do not waste unnecessary time accessing the drive.
4. C, CDROM, A. The search sequence will be as follows: hard drive, CD drive, floppy drive. This option is suitable for normal booting of the system from a hard drive.
5. CDROM, C, A. The CD drive will boot first. This option is used to install the operating system from the installation CD. Afterwards, you can return to booting from the hard drive first, so as not to waste time polling the drive every time you boot the computer.
6. D, A, SCSI. This option should only be used if the system has two hard drives and you need to boot from the second disk.
7. SCSI, A, C. This option is used if the operating system was installed on a hard drive with a SCSI interface. If it is impossible 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 first boot from the SuperDisk (LS-120) or ZIP drive. If there is no such media, the computer will try to boot from the hard drive. This option should only be used if you have one of the specified devices and need to boot from it.
In specific BIOS versions, other combinations are possible, for example A, C; A, SCSI, C; SCSI, C, A. In new versions BIOS parameter Boot Sequence is practically never encountered, and to set the boot order, several separate parameters are used, which will be discussed later.
First Boot Device.
This setting specifies the media for booting the system first. If this device cannot boot, 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 instead of Boot Sequence because they provide more flexibility in choosing the boot order.
The names of individual devices are used as values for the First Boot Device parameter:
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 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 – drive for CDs with a USB interface;
USB HDD – hard drive 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 parameters, you can configure any necessary boot sequence.
Recently, BIOS versions have become increasingly common, 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—the boot device is not selected.
Some BIOS versions only group certain categories of devices, such as hard drives, into groups. In this case, the list of values for the First Boot Device parameter can use both individual devices (from the list above) and their groups.
Recently, there have also been BIOS versions where the First Boot Device parameter contains only those drives that were actually detected. If the device connected to your 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 for booting the system; the values will be the same as for the First Boot Device parameter. Sometimes you can find a fourth boot device (however, the need for it is extremely rare), indicated by the 4th Boot Device parameter.
Hard Disk Boot Priority, Hard Disk Drives.
The Hard Disk Boot Priority, Hard Disk Drives parameter (Fig. 6.6) determines the boot order from hard drives, if there are several of them. 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 – Window for setting hard drive priority
To select a priority device, install it first in the list as follows.
1. Select the desired drive in the list using the cursor keys.
2. Press the “+” key on the additional numeric keypad to move the device up in the list (using the – key, respectively, down).
Installing a device first in the list does not guarantee priority booting from it, since the order is determined by the First/Second/Third Boot Device parameters. So, to boot the system from a hard drive, you need to specify the value Hard Disk for the First Boot Device parameter.
Removable Device Priority, Removable Drives.
To boot your computer, this option selects the device with removable media. Possible values are a list of devices supported by the system: Floppy, LS-120, ZIP-100, USB FDD, USB-ZIP, etc. In new BIOS versions, only those devices that are actually on the computer are available for selection.
The procedure for using this parameter is similar to the Hard Disk Boot Priority parameter.
CDROM Boot Priority, CDROM Drives.
To boot the computer, the parameter installs the CD drive; used similarly to the Removable Device Priority and Hard Disk Boot Priority parameters.
Boot Other Device, Try Other Boot Device.
The parameter allows you to boot 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.
This option allows you to boot your computer using local network, for which it must have a server that provides remote loading. 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 installed;
Here they come... BIOS... For some users, this abbreviation may be unfamiliar. And then they talk about activating booting from a flash drive. The devil is not as scary as he is painted. So, first things first.
What is BIOS
On any motherboard personal computer or laptop there is a special memory chip that stores the BIOS. BIOS (Basic Input/Output System) stands for basic system input/output. BIOS must include a program for initial computer setup ( SETUP), with which you can control various system parameters of your computer, for example, date, time, fan speed, device boot priorities...
Let’s talk about device loading priorities in more detail.
Which device does the BIOS try 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 will need to set the BIOS settings to the first boot CD-ROM device or Flash disk, depending on what media we plan to install the operating system from.
The problem is that to install the first boot device you need to enter the SETUP program. To do this, after turning on the computer, you need to press a certain key combination. Which one?
How to enter the BIOS to configure boot from a flash drive
BIOS different manufacturers Motherboards have different key combinations for entering SETUP. Typically, this is either the " DEL" (most often happens on desktops) or " F2" (most often happens with laptops). When turned on computer 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 prompt on how to enter the installation program does not appear or appears only for a moment, then you need to refer to the documentation for the motherboard. But there is no need to rush to do this. Usually it is enough to try pressing the keys " F10" (manufacturer HP), " F1" (manufactured by IBM and Phoenix) or " Esc"(manufacturer Toshiba). Well, if these keys did not help, then use the manufacturer's official documentation.
How to enable booting from a flash drive in BIOS
We figured out how to enter the installation program. Now you need to enable downloading from USB Flash. And here the same parsley awaits us again: 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 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- CD, Floppy or FDD- floppy disk reader, Removable Devices- replaceable devices ( removable drives and flash drives).
In some manufacturers' BIOS 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 Division(Other boot devices), Hard Disk Boot Priority(Boot priority for hard drives), and in BIOS from other manufacturers it will be necessary to move the device names from top to bottom, thereby increasing their boot priority.
Navigate through menu items in the BIOS using the cursor keys; selecting a menu item is done by pressing the key Enter. To move up (or back) a level, use the key Esc. Saving the settings changes made is done with the command SAVE and Exit SETUP(Save changes and exit installer) in the menu Exit or by pressing " F10".
Attention! Before activating in BIOS loading from a flash drive, insert this same 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 flash drive in the BIOS of different manufacturers

Award BIOS Advanced BIOS Features, then go to submenu Boot Sequence(Boot Seq & Floppy Setup) and select as First Boot Device device USB HDD. At the end, click " F10
Lenovo BIOS- you need to find an item in the menu Boot, then find the parameter Boot Priority Order and select the device USB HDD, then press " F6"to make it first. At the end, click " F10" to exit the installer and save the changes.
HP BIOS- you need to find an item in the menu Advanced, then go to item Boot options, select device USB Hard Drive. At the end, click " F10" to exit the installer and save the changes.
DELL BIOS- you need to find an item in the menu System, then go to item Boot Sequence and press Enter, then select the device USB Storage Device, press the key " U"to make the USB flash drive the first boot device. At the end, you need to exit the installation program and save the changes.
Well, in conclusion, I would like to inform you that it may turn out that the BIOS does not support booting from a flash drive (you simply do not find the USB HDD item). This can happen if the computer was purchased five years ago. The solution in this case will most likely be updating the BIOS version. 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.
Have you read the article and still don’t understand anything? In the article 05. Installing Ubuntu: BIOS setup, disk partitioning, installation I described in detail in pictures BIOS setup to boot from a flash drive using your computer as an example.
