Second Boot Device in Bios. How to put in BIOS download from a disk or USB flash drive? Possible difficulties in case of download from USB devices
This section contains three groups - Boot Device Priority., Boot Settings Configuration.and Security- In which settings are collected that affect the initial boot parameters of the operating system, the security BIOS, the load order from the available devices, etc.
Boot Device Priority.. Includes three parameters that determine the sequence of the selection of devices from which the operating system may attempt to boot.
– 1st Boot Device.- Indicates the source from which the operating system should try to boot first. By default, the parameter matters 1st floppy drive.. You can choose any other available download source, for which it is enough to click "-" or " + " In this case, the values \u200b\u200bof the parameter vary in places with the parameter values 2nd Boot Device.and 3rd Boot Device.shifting one position.
– 2nd Boot Device.- assigns a device from which the system should be loaded if the priority source is missing or for any reason unavailable. The default hard disk is chosen, for example PM-HDS72808OPLAT20.but you can specify any other device (as for 1st Boot Device.).
– 3rd Boot Device.- Indicates the device from which the operating system should be boosted if the first and second source are missing or not available. As the default parameter value, a CD / DVD drive is selected, for example SM-TSStcorp CD-ROM. You can change the download source in the same way as in previous cases.
Boot Settings Configuration.. Contains the parameters that affect the boot process, error processing, mouse initialization and keyboard, etc.
– Quick Boot- With it, you can force the BIOS to quickly test the RAM, which allows you to speed up the initial process of loading the operating system. By default, this parameter matters Enabled.. If a more thorough speed of RAM is required, you must select the option Disabled..
– Full Screen Logo.- Indicates BIOS that instead of text information (about the type and frequency of the processor, the amount of RAM, etc.) when the computer is restarted, you must display graphic imageBIOS recorded motherboard (Often this is an image with the name of the manufacturer of a computer or something like that). By default, this parameter is set to Enabled.. If post-information displayed when rebooting is more important, select option Disabled..
– BOOTUP NUM-LOCK- determines which state at the time of loading the operating system should be keys Numlock. By default, this parameter matters ON.What is convenient if you need to enter a login password containing a set of numbers. If there is no such need or need to be blocked, you can set the value Off.
– PS / 2 Mouse Support- Indicates BIOS if you need to support PS / 2-mouse on the initial loading process. Default assigned to the value AUTO.Also possible options. Disabled.and Enabled..
– Typematic Rate.- Allows you to adjust the speed of the keyboard, that is, the speed of the symbol appears when the key is pressed and the frequency of its repeat when it is deducted. The default value is set. Fast.corresponding to the fastest settings. To keep the keyboard in the inhibited mode, there is a value Slow..
– Parity Check.- Used to specify whether to perform the duration of the RAM. This feature is used only for memory modules with additional parity chips, which are usually installed on a server or other headcut. By default, this parameter is disabled. If you need to check the memory for parity, set the value for this parameter. Enabled..
– Boot to os / 2- Indicates whether the download will be in operating system OS / 2, since an important factor is the mechanism of operating system management rAMwhose volume exceeds 64 MB. The default value is set. No.What should be done if an operating system is used other than OS / 2. If there is an OS / 2 operating system, this parameter must be assigned a value Yes.
– Wait For 'F1' IF Error- Determines whether you need to expect keystrokes F1.if an error is detected at the initial stage of the computer loading. By default, the value Enabled.- If you have troubleshooting, an appropriate error message appears on the screen with the expectation of pressing the specified function key. If you set the value for this parameter Disabled.The computer will continue to boot in normal mode, ignoring the error occurring.
– HIT 'DEL' MESSAGE DISPLAY- Manages the appearance / hidden inscriptions about the way to enter the BIOS Setup. To go to the BIOS Setup, you must press the key Delete.(In the case of AMIBIOS). If this option is enabled, then the corresponding inscription will appear on the screen after turning on the computer. If this message needs to be hidden, assign the value to this parameter. Disabled..
Security. This group presents the parameters with which the safety of the BIOS is regulated. Here you can configure the password system to enter the BIOS.
– SUPERVISOR PASSWORD.- reports whether the administrator password is set to the BIOS input (or or download). If not installed, then there is an inscription Not Installed. To install a password, select the value Installed- will be active parameter Change Supervisor Password.. To enter the password you must press the key ENTERAnd then dial the password and confirm it.
– User password.- Informs whether the user password is set to the BIOS input (or or download the operating system). If not - the parameter matters Not Installedif installed - Installed. When you select the last value, additional parameters become available.
Using the parameter User Access Level(User Access Level) You can limit the level of access to the BIOS. By default, the value is set here. Full Access., however, options are possible. No Access.and Limited.
Often when repairing a computer, you need to change the download device. For example, you need to install Windows with CD / DVD or with flashki,
To change the priority of downloading a device, there is nothing complicated, just follow the instructions and everything will turn out.
First of all, you need to get into the BIOS itself, it is possible to do this when you turn on the computer and clicking on Del (Delete)other entry buttons can also be used Bios., Note At the bottom of the screen there is a press press button to enter Setup. In most cases, this is the DEL (DELETE) and F2 keys, rarely can be F1,
Consider two BIOS options Ami and Award.

Select item Boot Next, choose Boot Device Priority.
1st Boot Device - First Device
2nd Boot Device - Second Device
3rd Boot Device - Third Device And So on
The device loading priority is displayed sequentially if it is not possible to boot from the first device, it will be loaded from the second device and so on.
To change the order of the devices, select the first item and click ENTERThen the arrows select the device that must be downloaded first.
By producing all the necessary changes come out from the point (button ESC), then choose EXIT. Last two actions can be done by pressing F10. - It is to get out of Bios. and save changes. On the question "SAVE CONFIGURATION CHANGES AND EXIT NOW?" We answer OK (press ENTER).
The computer will restart and starts being downloaded from that device that you were first.
To change the download order in choosing arrows Advanced Bios Features..
Here also displays a serial order of loading devices.
First Boot Device - First Device
Second Boot Device - Second Device
Third Boot Device - Third Device
Select the first device and click ENTER, choose from the list the necessary device, press again ENTER.
Next, come out from the point Advanced Bios Features. We go to the item to save and go out - Save & Exit Setup. Or simply click F10.. On the proposal to save the changes made by us again, yes, the letter Y. The computer will restart and starts being downloaded from the first to the device you exhibit.
If something went wrong with you, you can always use item "Restore standard settings», Load Optimized Defaults or Load Setup Defaults.
Other identical names Options: 1st Boot Device, 1nd Boot Device, Boot Option # 1.
In BIOS, there are several options that allow you to determine the order of searching for boot devices. The category of such options includes the FIRST BOOT Device option. With it, the user can select the media from which the computer operating system is loaded.
After turning on the computer, the BIOS is checking all its components, and then proceeds to the search for the operating system or, more precisely, boot record - Special media partition, which indicates the location of the operating system, and also contains the code that initiates its loading. The operating system can be located on any of the carriers that are equipped with personal Computer. As an option, the First Boot Device option indicates the media on which the operating system is searched first.
The option may have two types of values. In the first case, indicate as options logic discs Computer, and in the second - physical drives. In addition, it may be indicated as a bootable media and a specific hard disk (HDD) if several are installed in the computer.
The First Boot Device option in the BIOS must be complemented by the Second Boot Device, Third Boot Device, Boot Other Device, which are responsible for finding all the others (following the first) boot devices. In some bIOS manufacturers At first, all these options were part of the option, but subsequently they were divided into several separate options.
We list the most popular options that may occur in this option:
- HDD - download is made with hard disk Computer. It is worth considering that hard disks The computer may have several. If we consider hard drives with the IDE interface, then there may be no more than 4 hard drives in the system - two Master and Slave disks on two IDE channels - Primary and Secondary. These four discs can be represented in options for HDD-0, HDD-1, HDD-2, HDD-3 options.
- SCSI - Loading is made from a hard disk or other device with SCSI interface.
- CDROM, DVDROM - Loading from a removable optical medium inserted into the CD-ROM drive.
- LS120 - Loading is made from the LS type drive, which is an improved drive for flexible discs with an increased capacity (usually 120 MB). Currently, the drives of this type are practically not used, so this option is not relevant.
- ZIP - download from Iomega Zip type device. Like the LS-120 drive, the ZIP drive is an improved analogue of the floppy drive and uses floppy disk with a capacity of 100 and 250 MB. Currently also applied rarely.
- USB-FDD, USB-ZIP, USB-HDD, USB-CDROM - Loading from portable media connected to uSB port. It can be a floppy drive, a ZIP type drive, a hard drive or a drive for optical disks.
Also, the option may have a discabled value, which implies a refusal to select any device as a boot.
In addition, sometimes not physical drives may be present as the option value, but logical disks. In this case, you need to know exactly what kind of logical disk is the storage device. For example, logic discs A and B are always reserved for floppy disk drives, and the rest (C, D, E, etc.), as a rule, belong to partitions on the hard disk. However, this option provides the user with a slightly wider choice, since logical disks It can be significantly more than physical hard drives.
What is the option to choose?
The option of the option value depends solely on the user's preferences and, of course, on which the storage device is the main operating system of the computer.
From time to time, any user, however, may need to be downloaded from different drives, as a rule, replaceable. There may also be necessary to change the order of loading devices. For example, for preventive maintenance of a computer or to restore the operating system, you may need to load not from the hard disk, but from removable media, such as a floppy or a CD.
In this case, it makes sense to establish as a first boot device any drive for removable media or a mobile drive, on which an operating system is installed with utility programs, and not HDD computer. And if any operating system is not yet installed on the hard drive of the computer, then loading from the interchangeable medium may be required to start the OS installation procedure.
Even if the operating system is installed on any of the HDD computer as the main one, the selection of the first-boot device of the removable medium does not prevent the loading of this operating system in the absence of this carrier. But in case of acute need to load from removable media, it will not be necessary to spend time on shift in BIOS Option Options.
Most often we remember BIOS ( Basic system I / O) only when we need to reinstall the operating system and you need to set the boot from the disk or flash drive in it. I often wrote about it in these articles like: and others. Now I want to gather together and refer only to this article if necessary. This article will be useful for all versions of bios and for different firms. Painter unified reference
The first thing you need to know - BIOS is divided by manufacturers and versions.
To change the boot method in BIOS - You must first enter it.
You can, of course, find out what version and manufacturer of your bios, from the manual going with the computer.
Also, it is possible to learn looking at the string at the top on the black screen when loading (the manufacturer will be indicated).
Well, then enter BIOS, knowing what you have.
In some versions of the bios, there is no such screen with a lines. There simply stands the logo and the bottom is written in the bottom. Something like "Press F2 to Enter Setup" means and press F2. If it is just a logo and there are no inscriptions - press ESC and then Del or F2
Here is a small list of manufacturers and shortcuts of keys to enter the BIOS:
Also at the bottom of the black screen, the keys are written to enter the BIOS and to output the list in which it is contained. available devices To download and so that you can boot from it. But about him at the end of the article.
As you can see - most often you need to press the key F2. or Del..
Now you need to put a flash drive or disk.
Consider on several examples different from the BIOS manufacturer.
Setting up Award BIOS to download from a flash drive or disk:
The main window is this kind in which we need a second point:
Further depends on the firmware version. In one case, you will need to go to the item similar to "BOOT SEQ & FLOPPY SETUP"
in another case, it is not necessary to go anywhere - everything will be so before our eyes
Schelkov on First Boot Device. (First boot unit), click ENTER and such a window will appear
in which you need to select a disk or flash drive that will be started first. You can specify the second boot device, for example, but usually the BIOS itself fills this data.
On a note:
If you choose a USB flash drive, then, among other things, you need to go to the item "Hard Disk Boot Priority "and move our USB flash drive to the very top with the" + "and" - "or" pagep "and" pagedown "buttons:
It is also worth remembering - that in order for BIOS to see the USB flash drive, you need to connect it until you turn on or before rebooting
Then click "F10" (see the exact key in the prompt at the bottom of the screen with the name "Save", "Exit") or exit the main menu of the bios and select the "Save and Exit Setup" item. In the red window, select "YES" with the "Y" button on the keyboard and press "ENTER"
Computer reboot and boot with installation disk With Windows, such a request may occur for a few seconds "Press Any Key to Boot From CD or DVD ..."
What is translated as "Press any button to boot from CD or DVD".
This means that if at this moment you do not press any button on the keyboard, then the computer will continue to load from the following device list.
Another variety of this bios:
I met only on the old computers of the decade ago until 2003. The main menu looks like this:
To customize the load order, you need to go to the menu Bios Features Setup.:
At this point, we just select the Pageup and Pagedown buttons (or ENTER and arrows) what to set first - CDROM or USB flash drive. Do not forget about the second and third device
And further:
How to choose where to boot in ami bios
If, entering the bios, you see such a screen, then you have Ami Bios.:
The button on the "Arrow right" keyboard is moving to the Boot tab:
We go to the "Hard Disk Drives" and in the "1st drive" line (may be called "First Drive") select the disk or flash drive:
Next we go to "Boot Device Priority", go to "1st boot device" and select from the list what has been chosen in the previous tab (i.e., if you choose a flash drive in Hard Disk Drives, then you need to specify it. This is important! )
To boot from the CD / DVD disc, you need to select "ATAPI CD-ROM" (or just "CDROM") in this menu, while there is no need to enter the previous menu "Hard Disk Drives".
Now we save the results with the "F10" button or go to the "Exit" bios section and select "Exit Saving Changes".
Another AMI BIOSbut everything is clear here:
Setting up Phoenix-Award BIOS to download from a flash drive
If, entering Bios, you see such a screen, then you have a Phoenix- Award Bios.:
We go to the "Advanced" tab and opposite the "First Boot Device" exhibit what you need (USBA or Disk):
Save the key F10.
Setting up EFI (UEFI) BIOS with graphical interface To download from a flash drive
Now you will not surprise anyone. Almost all new computers are supplied with a similar shell. You can read more about it in the article.
When loading, at the bottom of the screen there is a section "Boot Priority", where you can use the mouse (dragging) to set the desired load order.
You can also click in the right upper corner The "EXIT / ADVANCED MODE" button and select the Advanced Mode in the Advanced window that appears.
Next, go to the tab "BOOT" and in the section Boot Option Priorities. In the "Boot Option # 1" field, we install the default boot device, DVD-ROM, hDD or other available device.
How to boot from the flash drive or from the disk without entering bios
This is what I wrote about almost at the very beginning of the article.
This is when you need to press the key once and the window will appear with the download selection. This method does not change the BIOS settings.
Usually Award Bios. Offers to click "F9" to call the boot menu, and AMI asks to click "F8". On the Not Bugs, this can be the "F12" key.
In general, see the bottom line and look for Press F8 for BBS Popup or Press F9 to Select Booting Device After POST.
Why can't boot from flash drives in BIOS?
Possible reasons: 
On ancient computers, there is no possibility to load from USB flash drives. If there is no more than new bios, then the project can help.
1) Download the link above last version "Plop Boot Manager" and unpack.
2) There are files in the archive: plpbt.img is an image for a floppy disk, and plpbt.iso is an image for a CD.
3) Record the image on the disk and load from it (or from the diskette).
4) A menu will appear in which you choose your flash drive and already load from it.
Little decoding of disk designations when choosing:
Do not forget after you have done what they wanted (namely - why change the download in the BIOS) - return the download settings back to the computer loaded from the hard disk.
