In computing, booting is the process of starting a computer. … After it is switched on, a computer’s central processing unit (CPU) has no software in its main memory, so some process must load software into memory before it can be executed.
Booting is the process of restarting a computer or its operating system software. … Booting is of two types :1. Cold booting: When the computer is started after having been switched off. 2. Warm booting: When the operating system alone is restarted after a system crash or freeze.
The term “Booting” refers to the process in which your computer runs a set of instruction when the power is switched ON. This process loads the Operating System into the computer main memory. Once after this has been done, you can able to see the windows desktop and run applications.
What happens during booting?
Booting is what happens when a computer starts. … When you boot a computer, your processor looks for instructions in system ROM (the BIOS) and executes them. They normally ‘wake up’ peripheral equipment and search for the boot device. The boot device either loads the operating system or gets it from someplace else.
Why do many applications ask for a reboot after a successful installation?
This happens when you install some major applications. These applications require some services and the files to run in the background for the applications to run. But last time when you booted your system, Operating System is unaware of the application and not started the required services or the files in the background.
So, in order to run those services required by the applications, a Reboot is required so that the operating system to load the file and to start the services.
WHAT IS SAFE MODE BOOTING IN COMPUTER?
Safe mode is a diagnostic mode of a computer operating system (OS). It can also refer to a mode of operation by application software. Safe mode is intended to help fix most, if not all problems within an operating system. It is also widely used for removing rogue security software.
When Safe Mode Can Help
When Windows starts normally, it launches startup programs, fires up all the services configured to start, and loads the hardware drivers you have installed. If you start in Safe Mode, Windows uses a very low screen resolution with generic video drivers, doesn’t initialize much hardware support, starts only the necessary services, and avoids loading third-party startup programs.
Sometimes, you can start Windows in Safe Mode when you can’t start Windows normally, making it a good place to start troubleshooting potential problems. If your computer is infected with malware or has unstable hardware drivers that cause blue screens, Safe Mode can help you fix it because those things aren’t loaded the way they are when Windows starts normally.
If there’s a problem with your computer and you can’t seem to fix it—or if your computer is unstable and keeps crashing or blue-screening—you should drop into Safe Mode to fix it.
How to Start Windows In Safe Mode
Your Windows PC should automatically start up in Safe Mode if it crashes more than once while trying to start normally. However, you can also boot into Safe Mode manually:
- Windows 7 and earlier: Press the F8 key while the computer is booting (after the initial BIOS screen, but before the Windows loading screen), and then select Safe Mode in the menu that appears.
- Windows 8: Hold Shift while clicking Restart on the Power menu on either the login screen or through the Charms bar menu to begin the process.
- Windows 10: Hold Shift while clicking Restart on the “Power Options” submenu of the Start Menu. Click Troubleshoot > Advanced Options > Startup Settings > Restart. Press the “4” key when you see the Startup Settings screen.
How to Fix Your PC in Safe Mode
After starting Windows in Safe Mode, you can perform most of the regular system maintenance and troubleshooting tasks to fix your computer:
- Scan for Malware: Use your antivirus application to scan for malware and remove it in Safe Mode. Malware that may be impossible to remove in normal mode—because it’s running in the background and interfering with the antivirus—may be removable in Safe Mode. If you don’t have an antivirus installed, you should be able to download and install one in Safe Mode. Of course, if you’re using Windows Defender in Windows 10, you might be better off performing an offline malware scan.
- Run System Restore: If your computer was recently working fine but it’s now unstable, you can use System Restore to restore its system state to the earlier, known-good configuration. Assuming your computer is unstable and crashing, it may be possible to run System Restore without crashing from Safe Mode.
- Uninstall Recently Installed Software: If you recently installed software (such as a hardware driver or a program that includes a driver) and it’s causing your computer to blue-screen, you can uninstall that software from the Control Panel. Your computer should hopefully start normally after you’ve uninstalled the interfering software.
- Update Hardware Drivers: Assuming your hardware drivers are causing system instability, you may want to download and install updated drivers from your manufacturer’s website and install them in Safe Mode. If your computer is unstable, you’ll have to do this from Safe Mode—the hardware drivers won’t interfere and make your computer unstable in Safe Mode.
- See Whether a Crash Occurs: If your computer is unstable normally but works fine in Safe Mode, it’s likely that there’s a software problem causing your computer to crash. However, if the computer continues to crash in Safe Mode, this is often a sign that there’s a hardware problem with your computer. (Note that stability in Safe Mode doesn’t necessarily mean it’s a hardware problem. For example, your graphics card may be faulty and causing crashes under load. However, it may be stable in Safe Mode because your computer isn’t performing demanding operations with it.)
