Instructions

To open the BIOS, press Del after you turn on the computer and before the operating system starts loading. You may need to press a different key to enter the BIOS on your computer. In the lower left corner when checking random access memory there is an inscription Press Del to enter setup. If another key is written instead of Del, press it.

The BIOS window opens. You need to control the BIOS using arrow keys and the Enter and Esc keys. Basic parameters for equipment: Disabled – disable, Enabled – use. Depending on the manufacturer and model, the versions and directory names in the BIOS may differ. The following are the most common names.

In the Advanced menu (Advanced BIOS features) you can prohibit or use the USB controller under the USB Functions command (USB Controller/USB Ports/USB Device/Integrated (OnChip) USB Controller). The Enabled/Disabled command turns all USB ports on/off, Both makes all ports available, Primary makes ports on the rear panel only available. 2/4/6/8 USB Ports – number of ports available for operation.

• How to boot into BIOS from a bios 1984 flash drive

Installing Windows from a flash drive is very convenient. Storing Windows on a flash drive is much more secure than on a disk. Installing from a flash drive will also be faster than from a disk. There are times when the computer does not work or is simply missing optical drive(DVD/CD) ROM. Then installing from a flash drive is a very good way out of the situation. If you need to reinstall Windows on a laptop somewhere on the road, it will be more convenient to do this from a flash drive.

You will need

• Computer, Windows OS, flash drive, UltraISO program, program DAEMON Tools, Internet access

Instructions

First of all, you need to burn Windows to a flash drive. The capacity must be at least 4 gigabytes. Download the one you need Windows version from . The operating system downloaded from the Internet is in ISO format ( virtual disk). Next, download the UltraISO program. It will be needed in order to make it bootable.

Open Windows image using the UltraISO program. Go to the Boot menu and select Burn Disc Image. Creation bootable flash drive will destroy all information stored on it. Please take this into account. Insert the flash drive into your computer. The flash drive will appear in the program menu, select it. Select "USB-HDD" as the recording type and click "Record". The recording process will last from 10 to 25 minutes. Upon completion, you will be informed that the process has been successfully completed.

Restart your computer and continuously press the DEL key. This will take you to the BIOS. Select the “BOOT” line, then in the “BOOT DEVISE PRORITY” line select “USB-HDD”. Click on the “Save end Exit” command.

Computer and the process begins Windows installations from a flash drive. If you do not want to install Windows at this moment, simply remove the flash drive. In order to start the installation process, you just need to insert the USB flash drive into the USB port.

If you don't want to download Windows from the Internet and it is already on the disk, you need to convert it to ISO format. Download and install the DAEMON Tools program. Insert the disk with DAEMON Tools into the computer drive. In DAEMON Tools, select the File menu, select Create New Image. Once the process is complete, you will have Windows in an ISO, which you can burn and install Windows from it as described above.

New versions operating systems Windows includes a feature to create backup copy or image. It allows you to quickly bring the system to working condition without resorting to a complete reinstallation.

You will need

• - DVD disc.

Instructions

To create an image of the Windows Seven operating system, go to the “Control Panel” menu. Now open the System and Security menu and go to the Backup and Restore submenu.

Find the item “Create a system image” and click on it. Wait while the operating system prepares the files for archiving. Specify the location where the future OS image should be stored. To increase data security, it is recommended to use external USB drives. This will allow you to restore working condition systems even in the event of damage to the used hard drive.

Click "Next" after selecting the device to store the image. A window will open with a list of sections that will be included in the archive. Typically these are the system and boot partitions of the hard drive. Click the "Archive" button. This process takes quite a long time. It is better to leave the computer turned on at night.

Unfortunately, it is not enough to simply create an image. After all, it will need to be launched in the event of a system failure. Repeat the procedure for entering the “Backup and Restore” menu. Click the "Create a system repair disc" button.

Insert a blank DVD into a working drive. Click the "Create Disk" button. Wait until the required files are written. Please note that you can use a regular disk as a recovery disk. installation disk Windows Seven.

If the operating system stops loading, insert the created disk into the drive. Turn on your computer and press the F8 key. Select this DVD drive from the menu that appears. When a menu appears containing options for restoring the operating system, select “Restore the system from an image.”

Now specify the storage location for the archived copy of Windows. Wait until the Windows Seven OS image recovery process completes.

There are several ways to start installing the operating system. Inexperienced users often start it from the desktop. This often leads to the fact that the old OS is not removed, and the new one is simply installed on top of the old one. As a result, the user receives two operating systems, installed on the same hard drive partition. It is much more correct to start loading the OS from the BIOS.

Old Android devices support mass USB memory to transfer files to a computer and back. Modern Android devices use MTP and PTP protocols - you can choose either of the two.

To select a protocol USB connections, open the Settings application, click Memory, then the menu button and select USB connection to computer. When a device is connected to a computer via USB, the protocol it uses is shown in a notification.

Why modern devices Android does not support USB mass storage

USB mass storage—also known as the “USB mass storage device class”—is a method by which older Android versions provided the computer with access to their memory. When connecting an Android device to a computer, I had to click the “Connect memory to computer” button so that the device memory

Android became accessible to the computer via USB mass storage. When disconnecting from the computer, you should click the “Disable USB memory” button.

USB mass storage is a standard protocol used by flash drives, external hard drives, SD memory cards, and other USB storage devices. The drive becomes fully accessible to the computer, just like an internal drive.

This work scheme had disadvantages. The device connecting to the memory required exclusive access to it. The memory was disconnected from the operating system when connected to the computer Android systems. Files and applications stored on a memory card or USB drive became inaccessible when connected to a computer.

System files need to be stored somewhere; they cannot be detached from the device, so Android devices contain a separate /data partition for “ system memory” and /sdcard partition for “USB memory” on the same internal drive. Android installs applications and system files in /data, while user data is stored in the /sdcard partition.

Hard partitioning resulted in insufficient space for applications and too much space for data. You cannot change the size of partitions without obtaining superuser rights on the device - the manufacturer selects the size for each partition at the factory.

Since the file system had to be accessed from Windows computer, it was formatted under FAT. Microsoft holds patents on FAT, which is an older, slower file system without modern system permissions. to the present Android moment uses new file system ext4 for all partitions because Windows doesn't have to read them directly.

Connecting a phone or Android tablet to the computer as a standard USB storage device convenient, but it has too many disadvantages, so newer Android devices use different USB connection protocols.

MTP – storage device

MTP stands for “data transfer protocol”. Androids, when using this protocol, appear to the computer as a “data storage device.” Data Transfer Protocol was promoted as a standardized protocol for transferring audio files to digital music players With using Windows Media Player And similar programs. It was supposed to allow other media companies to compete with Apple's iPod and iTunes.

This protocol is very different from USB mass storage. Instead of exposing the Android device's file system to Windows, MTP works at the file level. Android device does not provide all of its memory to Windows. Instead, the computer sends a request to the connected device, and it responds with a list of files and directories. A computer can download a file by requesting it from a device, which will send the file over the connection. If the computer sends a file to the device, the device stores it. When you delete a file, the computer sends a signal to the device, telling it to delete the file, which the device does.

Android chooses which files to show and hides system files so they can't be seen or changed. If you try to delete or edit an immutable file, the device rejects the request and displays an error message.

The computer does not require exclusive access to the drive, so there is no need to connect memory, disconnect it, or create separate partitions for different types data. Android can use ext4 or any other file system. Windows is not required to understand the Android file system.

In fact, MTP works very similarly to USB mass storage. For example, the MTP device shows up in Explorer so you can view and transfer files. Linux also supports MTP through libmtp, which is included with popular Linux distributions. MTP devices also show up in the Linux file manager.

Apple Mac OS X does not support MTP at all. iPods, iPads and iPhones use their own proprietary syncing protocol with iTunes, so why would they support a competing protocol?

Google provides a transfer app Android files under Mac OS X. It is an MTP client and transfers files to Mac. Google does not provide this application for other operating systems because they have MTP support.

PTP – digital camera

PTP stands for Picture Transfer Protocol. When using this protocol, Android appears to the computer as a digital camera.

MTP is based on PTP but adds additional features. PTP functions similar to MTP and is used by digital cameras. Any program that captures photos from digital cameras can extract them from Android phone, if PTP mode is selected. PTP serves as a standard protocol for interfacing with digital cameras.

In this mode, the Android device will work with digital camera applications that support PTP, but not MTP. Mac OS X supports PTP, so you can use it to move photos from your Android device to your Mac over a USB connection without any special software.

In case of an older Android device, you will have to use USB mass storage. New devices allow you to choose between MTP and PTP - PTP is needed for programs that only support it.

If your device has a removable memory card, you can remove it and insert it directly into the memory card slot on your computer. The memory card will appear to the computer as a drive, which means you can access all the files on it, run file recovery software, and do everything else that MTP does not allow.

Turn on USB ports on a laptop you can through the BIOS, device manager, registry editor or editor group policies. If access to the USB connectors was intentionally prohibited using special software, then you can unblock it in a program where the interface is blocked. All methods are available ordinary users and do not require special training.

Disabling unnecessary devices

If the USB ports suddenly stopped working and you are now looking for how to turn them on, then the first thing to do is look to see if the device is connected to the laptop too much. When using a USB hub, the laptop may not be able to supply power to all devices, causing the USB ports to become unresponsive. Before you do USB setup in the BIOS, disconnect unnecessary equipment from the laptop and check if the ports work. If nothing has changed, then reboot the laptop and go into the BIOS.

Enabling ports in BIOS

To enter the BIOS during boot, press Delete, F2 or another key depending on the model motherboard. You can view it on the start screen.

In the case of a laptop, this screen does not appear because the fast boot feature is activated. You can temporarily disable this technology in the power settings:

Restart your computer. Without quick launch you will see all the stages Windows boot and you can get into the BIOS. If this doesn't work on Windows 8 or 10 with UEFI BIOS, try the following method:

Once rebooted, select Diagnostics, then go to Advanced Options and open UEFI Firmware Options. Click "Reboot", the next time you start, the BIOS UEFI interface will appear.

To configure USB ports in UEFI, you need to go to the “Peripherals” tab and set the “Legacy USB Support” parameter to “Enabled”. If support for USB 3.0 ports is required, activate the corresponding item (USB 3.0 Support).

In the AMI BIOS, go to the “Integrated Peripherals” section and set the four options to “Enabled”:

• USB EHCI Controller.
• USB Mouse Support.
• USB Keyboard Support.
• Legacy USB Storage Detect.

In Phoenix AwardBIOS, you need to go to the “Advanced” tab and go to the “USB configuration” section. All parameters inside must be set to “Enabled” for the USB ports to work.

In all BIOS versions, to save the configuration, you must press the F10 key and confirm the selection by writing “Y”.

Windows setup

If the ports are enabled in the BIOS, but connected via the interface USB devices are not detected by the system, then check the Registry Editor, Device Manager and Group Policy Editor. It is possible that changes were made to the system through them, due to which the ports are no longer working. You should start with the Registry Editor.

If the registry editor supports USB interface is enabled, then check the controller drivers in Device Manager.

If you see an icon next to the controller that looks like exclamation point, and you are sure that the interface is supported in the registry editor, then this means that there are problems with the drivers. First try updating the software:

If update software controller did not help, update the motherboard driver. Download it from the manufacturer's website and install it manually. Another way to update the drivers of all controllers at once is to remove them from the system. Right-click on the controllers and select "Delete". After a reboot, the system will automatically install controller drivers, so you no longer have to worry about how to enable the USB ports - they will work just like that.

If only removable devices connected via USB do not work, check in the Group Policy Editor to see if a read ban is set.

Find the option " Removable devices: Deny Reading" and set it to "Disable". The problem with identifying flash drives and external drives should disappear.

Hardware damage to ports

If the laptop's USB ports or the south bridge on the motherboard are damaged, then no methods will help enable the interface. Therefore, if the connectors stop working after mechanical impact or liquid getting inside the housing, short circuit or other negative factors, you should take the laptop to a service center for diagnostics.

In case of system unit Some USB ports can be replaced independently, but this is not possible on a laptop because all connectors are soldered to the motherboard.

If you go into developer mode, you can find a lot of items, most of which don’t mean anything to the average user at all. One of these items is called “USB Configuration”. What is this section and what is it for?

“USB Configuration” is a section with additional modes for connecting a smartphone via USB. In our example there are six of them:

• Charger

• RNDIS (USB Ethernet)

• Audio source

What is this section for? It is clear that to use a different device connection mode, however, in most cases the user does not need to enter this section at all. There is an opinion that here you can change the default USB connection mode of your smartphone. However, we were unable to do this, since the same mode is always used - MTP. At the same time, users on the network write that the default connection mode can be changed, but, for example, in the event of some kind of failure when the device is connected, say, only as a charger.

To find this section in the menu, go to settings.

Select "For Developers" mode.

If you do not find such a menu section, you need to enable it. How to do this, we.

You see a list of available modes.

If necessary, select the one you need.

USB ports may stop functioning if the drivers are lost, the BIOS settings are damaged, or the connectors become damaged. mechanical damage. The second case often occurs among owners of recently purchased or assembled computer, as well as for those who decided to install an additional USB port in motherboard or those who have previously reset the BIOS settings.

BIOS is divided into several versions and developers, therefore, each of them may have a significantly different interface, but the functionality for the most part remains the same.

Option 1: Award BIOS

This is the most common developer of basic I/O systems with a standard interface. The instructions for it look like this:

Option 2: Phoenix-Award & AMI BIOS

BIOS versions from developers such as Phoenix-Award and AMI have similar functionality, so they will be considered in one version. Instructions for setting up USB ports in this case look like this:

Option 3: UEFI interface

UEFI is a more modern analogue of BIOS with graphical interface and the ability to control using the mouse, but in general their functionality is very similar. The instructions for UEFI will look like this:

Connecting USB ports will not be difficult, regardless of the BIOS version. Once they are connected, you can connect a USB mouse and keyboard to your computer. If they were connected before, their operation will become more stable.
