Introductionm8dd86787a1fc2bc0_1528450127855_0Introduction

The teacher initiates a discussion about safe starting and switching off the computer and what should be done when the computer has been incorrectly turned off or unplugged.

If the computer has been incorrectly turned off or some problems have occurred during startup, a screen appears that allows you to select safe mode. When the systems does not want to start and you cannot repair it, starting it in safe mode may be the last chance for saving important data. Safe mode is used the most commonly to repair damaged device drivers and incorrectly installed programmes or to update the system.m8dd86787a1fc2bc0_1527752256679_0If the computer has been incorrectly turned off or some problems have occurred during startup, a screen appears that allows you to select safe mode.

Procedurem8dd86787a1fc2bc0_1528446435040_0Procedure

Safe mode:
Safe modesafe modeSafe mode is the option of the troubleshooting startup of the operating system with basic functionality. The system loads only needed device drivers and basic services then. Safe mode can help you troubleshoottroubleshoottroubleshoot most problems in the operating system. It is also widely used to remove malicious software. The inability to start the computer in safe mode may suggest hardware problems.

A device driver is a computer program that enables the interaction between a device connected to the computer and the computer system.

system servicesystem servicesystem service is a computer programme that ensures the functionality or the set of functionalities of the operating system.

Windows:
The older versions of the system enable to start it in safe mode during startup by pressing the F8 key. Newer versions, from Windows 8 onward, offer two alternative methods of starting the system in safe mode:

- from the sign‑in screensign‑in screensign‑in screen (Shift + Power + Restart),
- from Settings (Update & security – Recovery – Advanced startupadvanced startupAdvanced startup – Restart now).

[Illustration 1]

In Windows 10, if errors occur during startup, the Automatic Repairautomatic repairAutomatic Repair tool is run, but if it does not help, you must use the rescue or installation media. Safe Mode with Networking starts Windows in safe mode and includes the network drivers and services needed to access the Internet or other computers on your network. Safe Mode with Command Promptcommand promptCommand Prompt is also available for advanced users who are familiar with the  commands of the command prompt.

Mac OS:

Safe mode is started by pressing the Shift key immediately after the computer is switched on. The Shift key must be held until the Apple logo appears (along with the progress indicator). The mode starts the repair of the file system and disables all startup elements and login elements. Startup in single‑user mode (Command‑S) is also available for advanced users who are familiar with Linux. Unlike in Windows, in which Safe Mode with Networking is disabled by default, safe mode in Mac OS always includes restoring the network connections.m8dd86787a1fc2bc0_1527752263647_0Safe mode is started by pressing the Shift key immediately after the computer is switched on.

Linux:

Recovery mode can be selected on the list of the available systems of bootloader (startup programme). If the list is hidden during startup, press the ESC key. When you select recovery mode, the recovery menu is displayed with the following functions, among others:

- failsafex – boots your computer in a failsafe graphic mode,
- clean – attempts to make free space on the disc,
- dpkg – repairs broken software packages,
- fsck – repairs the file system,
- network – enables networking,
- root – runs a root shell prompt.

Android:

Safe modesafe modeSafe mode can be started on devices with Android only when the device is switched off. Press and hold the power button. On the displayed list of options select Power off by holding it with the finger. After a while the option Reboot to safe mode appears on the screen (on some devices you must hold the Restart button). In safe mode only default applications can be run, while third party tools are blocked.

Task 1

Start your computer in safe mode.

In order to leave safe mode in all the systems, you have to restart a device.

Some application software also offers safe mode. The examples of applications using safe mode are the Firefox and Internet Explorer browsers, which enable startup without add‑onsadd‑onsadd‑ons. Microsoft Outlook also can be started in safe mode, which allows to troubleshoottroubleshoottroubleshoot errors related to the support of electronic mail.

Task 2

On the internet find the information about starting your web browser in safe mode, without loading add‑onsadd‑onsadd‑ons. Start it in this mode.

Lesson summarym8dd86787a1fc2bc0_1528450119332_0Lesson summary

Windows Explorer started in safe modesafe modesafe mode operates normally, just as the drivers supporting USB ports, therefore you can connect an external drive or a pendrive and copy important data.
