In order to follow the instructions further, the bootable USB flash drive itself is required. The process of creating it is pretty simple. You will need the flash device itself, software and data that you want to use when starting up your personal computer.
During the preparation process, the program "UltraISO" will be used.
Preparation steps:
- Download the program to your computer using any browser convenient for you.
- After the download is complete, start the installation process and follow the instructions provided by the "Wizard-window".
- Further, when the software installation is completed, you should open the program and insert your flash drive into the port of the system unit.
- In the program window, select the "File" tab, where using the "Open" item you open the data you need to write.
- In the "Bootstrapping" tab, left-click on the "Burn Hard Disk Image" item.
- In the window that appears, find the "Disk Drive" selection line, where the name of the flash device should be.
- To complete the procedure for creating a bootable USB flash drive, you need to left-click on the "Write" button.
Working through the selection window
After you have created a bootable USB flash drive, connect it to a free port on the system unit and restart. When starting it, you need to methodically press the "F11" key, if nothing happens, then perhaps you have a different BIOS version, and you can try using the "F8", "F10" or "F12" keys.
A window should appear for selecting the boot of an external device, where you need to use the arrows on the keyboard to select the name of the flash drive.
Work throughBIOS
If you have problems with the previous method, then there is a reliable option - work through.
On a note! BIOS versions are different and each of them requires a special series of actions, but the principle of operation remains the same. In order to understand which version of BOIS you have on your PC, you must first call the main menu and see the similarity with the versions presented below.
To get started, you need to insert a flash drive into any free port in the system unit, restart the computer and at the time of computer start, often press the "Del" or "F2" key. If nothing happened, and the process of starting the operating system started, then restart the computer and look at the prompts in which the names of the keys should be written, for example "Tab" or "F1". It already depends on the BIOS version and manufacturer.
VersionAMI BIOS
If, after the performed key manipulations, this image appears on your monitor, then, undoubtedly, the BIOS version - AMI is installed on your personal computer.
Important! Before setting the startup priority, you need to verify that two functions work.
Now it's the turn to set boot priorities:
VersionAWARD BIOS
Enter BIOS using the steps outlined earlier. If this picture is on your screen, then follow the following plan:
- Go to the "Integrated Peripherals" line using the arrows on your keyboard. Both USB Controller and USB 2.0 Controller must be set to Enable.
- Then return to the higher level by pressing the "Esc" button once and select "Advanced BIOS Features".
- After entering the menu from the list of available functions, you will need the item "Hard Disk Boot Priority", where you will set your flash memory as a priority for loading. This is done in a simple way. Operating with arrows, select the name of the flash drive and by pressing the "+" key raise this name to the first position.
- You need to press "Esc" to perform the last action. We find the item "First Boot Device" in the "Advanced BIOS Features" section, and change the previous value to "USB-HDD".
- Then it remains to exit the BIOS, while saving the settings.
VersionPhoenix-Award Bios
After entering the BIOS, you should have the following picture if the BIOS version is Phoenix-Award.
The procedure is almost the same as in the previous version:
Video - How to put a boot from a USB flash drive in BIOS
The world does not stand still. Once the peak of popularity was to store information on disk or on a floppy disk. Now preference is given to more convenient and roomy flash drives.
To load into BIOS through a USB flash drive, several features must be taken into account:
- it is recommended to connect a removable disk to the connector located on the back of the system unit. It is he who is on the motherboard;
- connect the storage device before turning on or restarting the computer.
Regardless of the BIOS manufacturer, to boot Windows from a USB flash drive, you need to do the following steps:
- Open BIOS. To do this, press Delete or Esc... Service call keys may differ in different versions of the program. They are usually written at the bottom of the screen just before the operating system boots.
- Next, you need to turn on the USB controller.
- After that, the USB flash drive must be moved to the first place in the list of devices from which it is loaded.
- Save your changes.
Launch from a USB stick in Award Bios
This version of the program is called by the button DEL or a keyboard shortcut Ctrl + Alt + Esc (in older versions).
Go to the tab Integrated Peripheralsto turn on the USB controller. Near the inscription "USB Controller" and "USB Controller 2.0" set the value "Enable"... To do this, use the button Enter... Go back one step by pressing Esc.
Now we need to directly configure the boot from a USB flash drive to bios. To do this, go to the tab "Advanced BIOS Features"... Choose a section "Hard Disk Boot Priority"... Here, the first line should contain the name of the memory card. By default, this position is occupied by the hard disk. Using the key «+» , move the required line to the first place. Return to the previous menu.
Notice the line "First Boot Device"... Next to this inscription there should be "USB-HDD", which means booting from a USB stick or external hard drive. Sometimes the installation process may not go through. In this case, select the external floppy drive indicator - "USB FDD".
Hard Disk should be listed next to Second Boot Device.
After making changes, you can exit the BIOS, while saving the changes. Press Esc to exit to the main menu. Then press "Save & Exit Setup".
Installing a boot from a USB flash drive in AMI Bios
Exit to "AMI BIOS" is carried out by pressing the keys DEL or F2.
USB controller settings are in the tab "Advanced", In chapter "USB Configuration"... Index "Enable" should be near "USB Function" and "USB 2.0 Controller".
Return to the previous menu (Esc) and go to the tab "Boot", section "Hard Disk Drives"... The name of the flash drive must come first. Click on "Enter" on the first line and in a new window, select the desired item.
In the previous menu go to "Boot Device Priority"... There should be a flash card at the top.
After that, you can return to the main menu and exit the BIOS, saving the settings.
Set boot from USB to Phoenix-Award Bios
By clicking F1 or F2 you can open the BIOS version "Phoenix-Award" .
The USB controller section can be found under the tab "Peripherals"... Index "USB-HDD" need to be set in line "First Boot Device", tab "Advanced"... Remember to save your settings.
Configure boot from USB to Bios UEFI
New laptops released not earlier than 2013 have a special BIOS version. One of its features is the presence of protection against installing operating systems from any media, except for a licensed disk. To install a boot from a USB flash drive in this bios version, you must first disable this protection and set the compatibility mode with other operating systems.
After entering BIOS, go to the tab "Security", section "Secure Boot" and set the value there "Disabled".
In chapter "Boot", in line "Boot Mode" should be set to Legacy Support... In line "Boot Priority" should stand Legacy First.
This article describes the ability to set USB boot from device BIOS even if the motherboard BIOS does not have USB boot support.
The ability to install an operating system on a USB flash drive or have an image of a system (or even more than one) is always at hand, without dragging tablets with disks, has been appreciated by many for a long time. However, there is one rare but unpleasant point in this moment: sometimes you have to deal with computers of previous generations, the BIOS of motherboards of which simply does not support booting from USB. Hard disk, CDROM, flop anachronism ... But there is no USB support. So, turn around and leave. No matter how it is.
To install USB support in BIOS, we need:
- working ports USB and a working OS (for Method 1), working CDROM (for Method 2)
- program (Windows version must be at least Vista)
- well, a flash drive with the necessary files, of course ...
Set Boot to USB from BIOS: EasyBCD Program
The functions of the program do not tire me amazed for a long time, and, as you already understood, it can do much more than just change the names, order and method of loading operating systems. We have already used with success more than once when:
Now we will try to install support for booting from USB in the BIOS, even if there is no such item in the BIOS menu of the motherboard at all.
- We enter Windows of the problem computer and install the program EasyBCD
- In the program menu that opens, click on the button Add new entry (Add new entry)
- At the bottom of the screen, scroll to the right the items in the window Portable / External Media to BIOS Extensions ( BIOS Extender):
- and now it remains to install USB support by clicking on the button Install PLoP... At the bottom of the window, a corresponding message should appear about the successful installation of the virtual bootloader:
- go to the list of menu items by clicking on the button Edit menu download ( Edit boot menu) and we see that the boot menu has been diluted with the inscription EasyBCD BIOS Extender:
- check by reboot. And here it is:
Select and click. We are greeted by a new window with a choice of download sources. Among them are USB devices:
Set Boot to USB from BIOS: External Boot Loader
You can do the same, only without the EasyBCD program. We'll have to go the more difficult path and download (and then write down to disk) a special bootloader, and follow the same installation path. The conditions here are slightly different: Windows may be faulty, but the drive should work. The bootloader image can be downloaded from:
https://www.plop.at/en/bootmanager/download.htmlunpack the zip archive and write it to disk. The desired image lies here.
Installing, reinstalling and restoring the operating system, as well as carrying out some types of diagnostic work, as a rule, requires the mandatory use of special boot disks or flash drives. But in order for the computer to boot from external media, the appropriate priority should be set in the settings of the basic input-output system or otherwise BIOSa, that is, literally indicate from which source the system should boot.
The procedure for configuring boot from external media is quite simple, however, it raises many questions for many novice users. And this is quite understandable. Firstly, you rarely have to face the need for such a boot, and secondly, in different computer models, the procedure for entering the BIOS and changing boot priorities may differ in detail. Let's consider everything in more detail.
There are currently two types of basic I / O system: the classic BIOS and its enhanced UEFI. Both of them are special programs written on the motherboard microcircuit and designed to configure and check the readiness of hardware components, and transfer control of the PC to the operating system. Unlike BIOS, UEFI is more autonomous, it has a convenient graphical interface with mouse support, allows you to integrate drivers, run executable files in EFI format, and work with GPT disks without restrictions. In addition, computers with UEFI start up an order of magnitude faster than PCs with a regular BIOS.
How to get into BIOS or UEFI
To get into the BIOS or UEFI, immediately after turning on the computer, press and hold the Del, F2, or Esc button. Which button should be used to enter BIOS / UEFI on your desktop or laptop model should be specified in the supplied user manual. However, on newer Windows 8.1 computers, this can be problematic. If fast boot technology is activated in the system, you simply will not have time to press Del or F2 in time. In this case, follow these steps:
Discover Settings -\u003e Change PC settings -\u003e Update and recovery -\u003e Recovery -\u003e Special boot options, and then click Restart Now. After rebooting, you will be taken to the Select Action window. Click on Diagnostics -\u003e Advanced Options -\u003e UEFI Firmware Options... The computer will restart and you will be taken directly to the UEFI interface.
Note
Determining which interface your computer is using is very easy. To do this, press Win + R and execute the msinfo32 command in the window that opens, and then in the system information window, find the item "BIOS mode". The old version of the I / O system will be marked "Deprecated", the new one will be "UEFI".
Configuring boot from CD / DVD / flash drive in BIOS
In most BIOS versions, the Boot section is responsible for configuring boot options.
It is he who contains a list of all devices connected to the computer. Since the hard drive and CD-ROM are built-in components, they will be present in the list anyway, but if you want a flash drive there, you must insert it into the USB port in advance, even before entering the BIOS. The first in the list is the device from which the system is currently booting. Using the arrow keys, you can change the boot priority, and by pressing the F10 key, apply the new settings.
In some BIOS versions, the Boot section may have additional options, in particular Boot Device Priority, Hard Disk Drives, and so on.
If booting from a CD / DVD or a regular flash drive, it will be enough to move this device to the top of the list in Boot Device Priority and save the settings. If the flash drive is formatted as HDD, you will first need to go to Hard Disk Drives, select the first device (1st Drive) in the list, press Enter and specify the flash drive in the menu that appears. Then the same will need to be done in the Boot Device Priority subsection. We save the settings with the F10 key. This is the case for AMI BIOSes.
The procedure for configuring boot from DVD / flash drive in BIOS AWARD or Phoenix is \u200b\u200bslightly different. Here in the main BIOS menu you need to find the Advanced BIOS Features section, and in it find the First Boot Device item, which is responsible for prioritizing boot devices. Being on the First Boot Device, press Enter and in the menu that opens (list of devices) select CD-ROM or, if available, a USB flash drive. If there is no flash drive in the list, switch to the first item of Hard Disk Boot Priority, press Enter, select our flash drive in the list, move it up the list. To save the settings, press Esc twice, and then Save and Exit Setup and confirm saving the parameters with the Y key.
Configuring boot from CD / DVD / USB stick to UEFI
Setting boot priority in UEFI is easier, and not just because you can use a mouse. Most UEFI interfaces have a Boot Priority panel at the bottom of the window, which displays all devices connected to the computer, including flash drives and removable HDDs. To install a boot from a particular device, just drag it with the mouse to the beginning of the panel, and then save the new settings when exiting UEFI.
You can also click the "Exit / Advanced mode" button, go to the Boot tab in the window that opens, select "Boot Option # 1" in the Boot Option Priorities list and set a USB flash drive, hard drive, CD-ROM or other connected to computer device.
New settings are saved when exiting UEFI or pressing the F10 key.
Have a great day!
In previous articles, it was described in detail how you can get into BIOS on different models of laptops and computers. But for what purpose is it necessary? In most situations, entering the BIOS is required to change the default boot disk.
This text explains how to boot from a disk or flash drive on several variants of computers. The same principle works on different devices. Moreover, its observance requires only a minimum of logic and care.
Two methods to boot from a disk or flash drive
In the first option, it is proposed to put in SETUP (aka BIOS) the desired device to boot by default. In practice, it will look like this: any time the computer is turned on, it will start from the specified hardware. If the device is not available or is not suitable for downloading, the system will try to do it from the next one in the list, which can also be designated. If that doesn't work, the computer will go to the third device, and so on.
The next method is supported by almost all modern laptops or stationary solutions. It is enough to turn on the menu to select the boot during the start of the computer. Thus, the device is determined from which the system will start only once. This is a more convenient method in a situation where you need to boot the system from a USB flash drive one time.
When using the first method to select a boot device in BIOS, go into it and see the available interface. If you are greeted by blue windows, then in front of you - Award, grayish differs AMI, and the graphic design indicates UEFI... There are others. To determine, you just need to study the screenshots and compare with your interface.
If you have an Award
Enter SETUP, go to " Advanced BIOS Features". By default, this item is placed second or third, starting from the top.
In another situation, the required sections can be seen immediately.
Now let's define the necessary items in the menu.
First Boot Device means the hardware from which the computer will start in the first place.
Second Boot Device uses the system in the event that the first device is not suitable for boot.
TO Third Boot Device the computer will switch if there are problems with the second equipment in the list.
Any item from such "X Boot Device" corresponds to a hard disk, USB flash drive, CD / DVD or other boot device.
If none of the options fit and Boot Other Device is set to Enabled, then the operating system will be searched for on other drives.
When choosing opposite to any "X Boot Device" Hard Drive, ie. hard disk, the item Hard Disk Boot Priority allows you to specify in more detail which disk to use. This point also applies to flash drives, since this type of boot device is defined by the computer as an external hard drive.
Therefore, to start from a DVD or CD, you need to assign "ATAPI CD" or "CDROM" in the "First Boot Device" item and do not select anything else. However, to boot from a USB flash drive, you need not only to click on "Hard Drive", but also go to the "Hard Disk Boot Priority" section. There, using the buttons "PageUp" and "PageDown" or "+" and "-", move the flash drive up to the very beginning of the list.
Please note! The flash drive is connected to the computer before rebooting or turning on. Otherwise, it is far from the fact that BIOS will see it.
The name of the flash drive may look different. Usually it starts with "USB ...", "Generic USB ...", and sometimes "External Device". The result of all the actions performed must be saved. It is enough just to press the button " F10"(For clarification, look down the screen at the prompts: there should be the words" Save "and" Exit ") or even return to the main menu and there already select" Save and Exit Setup". In the red window that appears, use the "Y" button to agree with "Yes" and press "Enter".
Literal translation of the phrase: "Press any key to load a CD or DVD ...". This means that you can press any button and the computer starts from the disks. If you do nothing, it will boot from the next equipment in the list.
Boot selection process in AMI BIOS
Such BIOSes have a completely different look compared to the Award version. First, we get into SETUP and look for the section “ Boot»Button to the right. There are two necessary items here, they can be clearly seen in the screenshot.
To install a boot from a hard disk or flash drive, you need a tab Hard Disk Drives... Select it and in the line "First Drive" (sometimes called "1st Drive") put our flash drive (USB device). After that, you should return to the previous section. Let's press the "ESC" button.
Then go to Boot Device Priority. We select 1st Boot Device and again from the list - a USB flash drive.
Be careful, the selected devices must match! If a hard disk is assigned in the first step, then you need to put not a USB flash drive in the list, but it.
When you need to boot from a CD / DVD, select "CDROM" (sometimes "ATAPI CD-ROM") in the same menu. And in this case, the "Hard Disk Drives" section is no longer needed. Save the settings with the " F10"Or you can just go to the" Exit "item and click" Exit Saving Changes».
A request will appear, we answer "OK".
On different models of laptops and computers, everything is pretty similar. For example, on a standard laptop from Lenovo, the "Boot" section includes all the equipment at once, which is very convenient for users. Eliminated confusion with additional subsections and priority. To set the order of loading the equipment, you just need to use the keys " F5 / F6". Therefore, to start from a USB stick, simply push it all the way to the top.
Some users will need a detailed transcript.
- USB HDD means external hard drive or USB flash drive.
- How ATAPI CD is defined by CD or DVD-ROM.
- HDD (sometimes ATA HDD) is a hard drive.
- USB FDD - External floppy disk drive.
- USB CD - drive for external disc type.
- PCI LAN stands for LAN Boot.
On Lenovo G500 models, press the OneKey Recovery button while the notebook is off.
Below you can clearly see the BIOS EFI (UEFI), which differs not only in the graphical interface, but also in the working mouse. If you have a computer with EFI, then when you enter the BIOS you will be greeted with such an image.
There is a menu at the bottom of the screen Boot Priority... Here you can use the drag-and-drop method to make the required loading order. In addition, by pressing the "Exit / Advanced mode" button located in the upper right, you can go to the advanced version. To do this, in the window that appears, select Advanced mode. Then find the "Boot" section and in the Boot Option Priorities tab in the "Boot Option # 1" field, put the required boot device: DVD-ROM, USB flash drive, hard drive or other available equipment.
But computer owners Hewlett-Packard usually the following picture awaits when switching to BIOS.
Find the required device in the "Storage -\u003e Boot order" menu and press "Enter". Move it up and when it is at the beginning press "Enter" too. Select "File -\u003e Save and Exit" to save the settings.
Methods for booting from a disk or flash drive without going into BIOS
It was already mentioned above that almost any modern laptops and computers are designed for a one-time boot from the required device and for this you do not need to contact the BIOS. It is only necessary to press a certain button when starting your computer. For example, in this BIOS Award it is proposed to select “ F12»And call the boot menu.
Usually it is written something like "Press F12 Boot Menu". This means: press "F12" to select the boot equipment. We do this and we see the image as in the screenshot below.
The list contains found devices. Select a CD / DVD disc, USB flash drive or something else and press "Enter". However, other options are possible in AMI BIOS.
The inscription "Press F8 for BBS POPUP" requires pressing "F8" for a menu with a choice to appear. On laptops, sometimes you need the F12 button to call it. The boot menu looks like the screenshot.
It is enough to select the required one and wait for loading from a CD or USB flash drive.
Potential Difficulties When Booting from USB Devices
Problems sometimes arise and the computer does not boot. Let's dwell on common difficulties. First, make sure that the USB controller in the BIOS is not disabled. In the Award, this information is checked in the “Integrated Peripherals” or “Advanced Chipset Features”. You need to see the function "USB Controller" and "USB Controller 2" their status should be "Enabled".
In the case of AMI, you need to find "USB 2.0 Controller" in the "Advanced" menu. The position should be "Enabled". The "USB 2.0 Controller Mode" option requires the "HiSpeed" status.
In addition, the reason may lie in the slots located in front of the system unit panel. It is worth trying to connect the USB stick to the rear inputs of the computer.
If your SETUP resembles this photo, then in the "Startup" section, change the "UEFI / Legacy Boot" parameter to "Legacy Only".
In addition, the problem may be the disk or flash drive. Bootstrap is required! You can check this on another working computer.
For fairly old computers in general. If there is no newer version of BIOS, then the PLOP solution can help. Download the latest version of Plop Boot Manager, unpack the archive. You will see the files, of which plpbt.iso is the image for the CD, and plpbt.img is for the floppy disk.
It is clear that if there is a floppy disk, then the corresponding image is written to it, and the image for the disk is placed on the CD-R / RW disc. It will not work just to write the file to the media: there is special software for the image. This topic was described in the OS installation instructions. Then you start from a CD or floppy disk, select the device in the window. The method helps to boot from flash drives on the most ancient computers.
Summarize
You have studied a detailed guide on booting from a disk or flash drive in a variety of cases. If you need it only for one time, then it is better to use the menu, which does not require switching to BIOS. With constant downloads or if there is simply no such menu of choice, then just configure the BIOS well. Do not forget to bring everything back later.
