Basics of Fixing and Windows 8 or 10 PC

Leave a comment

I just opened a computer repair business from my home and I just got my first and I been working in IT for 15 years.  Here a some of my notes on repairing Windows 8 and 10 PC.

Generally, this for a corrupted OS. I post a later article on Malware and Virus removal.
The most import thing is below.

Important!!! Hardware needed!

Do not use a Bluetooth keyboard and mouse, I a regular keyboard and mouse for repair, because Bluetooth keyboard and mouse may work under the BIOS but lose connection when the BIOS gives control to the OS and if OS doesn’t boot or load properly you may not be able to boot the Windows OS in safe mode or recovery mode.

I found must problem can be solved in Window 8 and 10 once you access recovery mode, but during an Automatic Repair loop, when the PC just keeps going into repair and Bluetooth Keyboard can’t communicate with the OS.

So attach a good out USB wired keyboard to the PC for recovery.  Follow the steps below:

Getting into Recovery/Safe Mode:

  1. Press the Power Button three times and the system to boot into recovery/safe mode.

 

How can you get F8 work again? 

F8 boot menu feature is disabled on Windows 10 by default. The good news is you can get it to work again with the Boot Configuration Data (BCD) Edit command. BCD Edit is a tool written to control how the operating system is started. You can use it to enable the F8 boot menu easily. Just follow these steps:

1) On your keyboard, press Windows logo key and R key at the same time to invoke the run command.

2) Type cmd then press Ctrl+Shift+Enter to open an administrator command prompt. (Don’t just press Enter or click OK as that won’t open the command prompt in an administrator mode.)

3) Copy the following command and paste it in the Command Prompt. Then on your keyboard, press the Enter key.

bcdedit /set {default} bootmenupolicy legacy

4) Reboot your PC. Before the Windows logo appears, press F8 to access the Boot Options menu (see below screenshot). Then select Safe Mode.

 

Notes: If F8 is disabled by default if you want to use F8 you need to enable it. You can get F8 work again only when you’re able to access Windows. If you can’t start Windows normally, you need to use another effective way.

If the Windows including Windows 10 or Windows 8 fails to boot, it will launch its built-in tool –Automatic Repair to attempt to repair Windows. However, Automatic Repair has some limitations. Sometimes, like any other programs, Automatic Repair fails to work and you get an error message – Automatic Repair couldn’t repair your PC.

What should we do if we stuck in Windows Automatic Repair loop? How to solve this issue with ease?

Disclaimer: please always make a backup copy of your files before using any of the advice provided here. If not sure, seek qualified assistance before proceeding on your own!

Fortunately, Bootable installation media or Recovery Drive/System Repair Disc can help to fix Automatic Repair couldn’t repair your PC error. Here are 7 quick fixes to help you get out of Windows Automatic Repair loop.

Step 1 

Safe mode starts Windows in a basic state, using a limited set of files and drivers. It can help you troubleshoot problems on your PC. For example, if the problem doesn’t happen in safe mode, you’ll know default settings and basic device drivers aren’t causing the issue.

There are two versions of safe mode: Safe Mode and Safe Mode with Networking. They’re quite similar, but Safe Mode with Networking includes the network drivers and services you’ll need to access the Internet and other computers on your network.

Select from the following sections to find out how to start your PC in safe mode from either Setting, from the sign-in screen, or from a black or blank screen.

  1. Press Windows logo key  + I on your keyboard to open Settings. If that doesn’t work, select the Start button, then select Settings.
  2. Select Update & Security  > Recovery.
  3. Under Advanced startup, select Restart now.
  4. After your PC restarts to the Choose an option screen, select Troubleshoot > Advanced options > Startup Settings > Restart.
    Choose an option screen in the Windows Recovery Environment.
    Troubleshoot screen in the Windows Recovery Environment.
    Advanced options screen in the Windows Recovery Environment.
    Startup Settings screen in the Windows Recovery Environment.
  5. After your PC restarts, you’ll see a list of options. Select 4 or press F4 to start your PC in Safe Mode. Or if you’ll need to use the Internet, select 5 or press F5 for Safe Mode with Networking.

From the sign-in screen

  1. Restart your device by pressing the Shift key while you select the Power button on the bottom right corner of the sign-in screen.
  2. After your PC restarts to the Choose an option screen, select Troubleshoot > Advanced options > Startup Settings > Restart.
    Choose an option screen in the Windows Recovery Environment.
    Troubleshoot screen in the Windows Recovery Environment.
    Advanced options screen in the Windows Recovery Environment.
    Startup Settings screen in the Windows Recovery Environment.
  3. After your PC restarts, you’ll see a list of options. Select 4 or F4 to start your PC in safe mode. Or if you’ll need to use the Internet, select 5 or F5 for Safe Mode with Networking.

From a black or blank screen

Before you enter safe mode, you need to enter the Windows Recovery Environment (winRE). To do this, you will repeatedly turn your device off, then on:

  1. Hold down the power button for 10 seconds to turn off your device.
  2. Press the power button again to turn on your device.
  3. On the first sign that Windows has started (for example, some devices show the manufacturer’s logo when restarting) hold down the power button for 10 seconds to turn off your device.
  4. Press the power button again to turn on your device.
  5. When Windows restarts, hold down the power button for 10 seconds to turn off your device.
  6. Press the power button again to turn on your device.
  7. Allow your device to fully restart. You will enter winRE.

Now that you are in winRE, you will follow these steps to take you to safe mode:

  1. On the Choose an option screen, select Troubleshoot > Advanced options > Startup Settings > Restart.
    Choose an option screen in the Windows Recovery Environment.
    Troubleshoot screen in the Windows Recovery Environment.
    Advanced options screen in the Windows Recovery Environment.
    Startup Settings screen in the Windows Recovery Environment.
  2. After your device restarts, you’ll see a list of options. Select option 5 from the list or press F5 for Safe Mode with Networking.

If you need more info on a black or blank screen error, see Troubleshoot black or blank screen errors.

Note: no matter which you choose, your some data might be deleted during the refresh or reset process. It is recommended to backup your important files before taking this step. You can check this tutorial to know how to recover data when the PC won’t boot quickly and effectively.

Using Systems Restore:

System Restore

If you have enabled System Protection before and created a restore point, you can perform System Restore to fix Windows 10 /8 automatic repair loop.

Step 1 When you see Advanced Startup Options screen, click Troubleshoot > Advanced options > System Restore.

Step 2 Select a restore point that created before the automatic repair loop. Windows will restore your computer to the original status.

These are personal notes I have collected from various websites and my own personal experiences in the field.  They focus on using the built-in tools Microsoft built into Windows 8 and 10.

You should not need to buy someones third-party applications to fix your PC, and Use should using both Windows System Restore and Windows Backup utilities.  I will write and separate article on using Windows System Restore and Windows Backup to protect your PC. if you a google account the Google cloud backup is another great backup tool to protect your data.
