No Bootable Device error

By Susan C on April 22, 2018

The “no bootable device” error is like a nightmare for Windows users. Many users who get this error find themselves helpless and unable to understand what is wrong with their computer that worked well until yesterday.

With that said, you don’t have to worry about this error anymore. On this page, you’ll find easy-to-do solutions for no bootable device error.

Note: The 2^nd, 3^rd, and 4^th solution given in the list would require Windows installation media such as DVD or USB drive with Windows installation files.

BIOS Drivers – Common Errors and Fixes

Solution One- Check the boot order in BIOS

Every time you start windows computer, it checks the BIOS for the boot order. It looks for files like NTLDR and other boot files in the volume boot record before it can start Windows OS. If it does not find files in the first boot device or the second, it throws up an error, like no bootable device.

To resolve the error, you need to ensure the hard drive is the first bootable device in the BIOS.

Here are the steps to check the boot order in BIOS and make changes if necessary.

When your computer starts, the BIOS flash screen/POST screen shows the keys that allow access to BIOS and other features.

Here are the steps to follow to fix the issue.

Depending on your device or motherboard make and model, press the right key to access BIOS Setup
Once you enter the BIOS Setup, look for Boot or Advanced options and press the right key to access that tab. (Note- the navigation keys are shown at the bottom of the BIOS screen)

Check the first boot device. If you see first boot device as USB CD-ROM, Flash drive or any other option other than hard drive, you need to change it

Select the first boot device using the suggested navigation keys and select Hard Drive as the first boot device.

Press F10 or any other key as suggested in BIOS setup to save the changes and exit BIOS setup

The Windows system should reboot normally which indicates the “no bootable device” error is resolved. If you still get the error, perform the steps in Solution two

Solution Two – Rebuild boot information

If the Master Boot Record (MBR) or BCD (Boot Configuration Data) is corrupted, your Windows system can throw up an error like “no bootable device”. The solution to this problem is rebuilding boot information.

However, you will need Windows installation disc to perform steps given below.

Insert the installation media (USB/CD) in your computer and boot from it. You need to check the BIOS Flash/POST screen to know the right key to access Boot menu
Select the right bootable device (USB/CD-ROM) depending on the type of windows installation you have.
When the Windows 10 boot media loads, you will see a screen with the option to Repair your computer, click it

In the next screen, select Troubleshoot

In the next screen, select Advanced options

In the Advanced options screen, select Command prompt

If you are using Windows 7 computer, follow the steps given below
When the Windows 7 boot media loads, you will get a window with system recovery options
Select the option –Use recovery tools that can help fix problems starting Windows

Select the drive where Windows 7 is installed and click Next
In the next screen, select Command Prompt

The steps given below are the same for Windows 7 and Windows 10 users

In the command prompt window, type the following commands one after another and press Enter after each command. If you are prompted to add a new installation to boot list, press Y on the keyboard

bootrec /fixmbr
bootrec /fixboot
bootrec /scanos
bootrec /rebuildbcd
Type Exit in command prompt window and restart your computer

The no bootable device error should be gone and the computer should boot normally.

If the no bootable device error persists, try the steps in Solution Three.

Solution Three – Set the primary partition as active

For the windows to boot normally, the primary partition in which installation files are stored should be set as active. It is quite possible you made some accidental changes when making new partitions or modifying partitions on your computer. This can lead to no bootable device error.

The solution to this problem is set the primary partition as active.

Here are the steps to follow.

Refer the steps given in Solution Two to boot from installation media and perform steps until you get access to the command prompt
In the command prompt window, type the following commands in the given order and press Enter after typing each command

diskpart
list disk
In the list of disks, you need to select the disk where Windows is installed. If you have only one hard drive, you will only see one disk in the list which is labeled as 0(zero)
Type select disk 0 and press Enter
Type list partition and press Enter
You should see all partitions on your hard drive. You need to select the partition that has Windows installed that is your system partition
Type select partition 1 or whatever is applicable in your case and press Enter

Type active and press Enter
Type Exit in command prompt
Restart the computer

The system partition is now set active which would resolve the “no bootable device” error. If the error is still not resolved, the last option is to Reset the PC which would fix the issue.

DNS Server not responding Error

By Susan C on April 20, 2018

Are you getting an error “The DNS server isn’t responding”?

Do you frequently get an error message which says “your computer appears to be correctly configured, but the device or resource (DNS server) is not responding”?

We know it can be difficult when you get such errors because they prevent you from accessing the Internet.

But don’t worry; we offer some easy solutions to solve such errors.

However, let’s first learn more about this issue and its impact.

Why DNS server not responding error doesn’t let you from accessing the Internet?

The username and password provided by ISP to connect to the Internet are only part of the process of Internet connectivity.

There are a host of other things working in the backdrop that make internet connectivity possible, and DNS server is one of the more important part of the whole process.

DNS stands for Domain Name Server. The DNS server translates the web address you type in the browser to IP address and help your browser to connect to that website.

For example, when you type drivers.com in your Chrome address bar, the DNS server translates it to the public IP address of 192.XXX.XXX.18 and connects your browser to drivers.com website.

So, if the DNS server is not functioning properly, you won’t be able to visit sites like you normally do.

In this post, we have provided you with four solutions to fix this error.

How to fix DNS server not responding issue?

The solutions given below are based on different causes that lead to DNS server not responding issue.

Unless you know the exact cause, it would be hard to predict which solution would work for you. Hence we suggest you try the first solution and then the next and so on until the DNS server issue is resolved.

Solution One – Select right settings for DNS server address

One of the reasons behind the DNS server not responding could be wrong DNS server address.

The simplest solution to this problem is to select right settings for DNS server addresses.

Press Windows key and R simultaneously on the keyboard to invoke Run command
Type control in the Run command box and hit Enter
Set the View by Large Icons and select Network and Sharing center

In the left-hand pane, click Change adapter settings

Right-click on Wi-Fi or Ethernet as per your Internet connection and click Properties

In the Wi-Fi properties window, select Internet Protocol Version 4(TCP/IPv4)

Select Obtain an IP address automatically and Obtain DNS server address automatically options
Click OK

Now go to Wi-Fi properties window again, select Internet Protocol Version 6(TCP/IPv6) this time and click Properties

Select Obtain an IP address automatically and Obtain DNS server address automatically options

Click OK
Close all windows
Try accessing some websites and see if the DNS server not responding issue is resolved.

Solution Two – Clear DNS Cache and Reset IP

By default, Windows stores DNS cache for 1 day for all websites you visit. It also includes negative DNS responses which are stored for around 5 minutes.

Clearing DNS cache forces the Windows to retrieve fresh IP addresses for websites you want to visit.

Here are the steps to clear DNS cache.

Go to Desktop
Type cmd in the search box
In the list of results, right-click Command Prompt and select Run as administrator

In the User Account Control window, click Yes
In the command prompt window, type the following command and press Enter on the keyboard after every command

ipconfig /flushdns
ipconfig /registerdns
ipconfig /release
ipconfig /renew

Close the command prompt window
Try to access some websites and see if the DNS server not responding issue is resolved

Windows Modules Installer Worker High CPU Usage issue

By Susan C on April 19, 2018

Are you troubled by high CPU usage by the Windows Modules Installer Worker process?

Does your task manager shows you a picture like the one below?

If yes, it means your PC performance has been compromised by the Windows Modules Installer Worker process. It is notorious for hogging CPU power leaving very little CPU processing power for other Windows components and critical services.

Many Windows 10 users have complained about this issue. Thankfully there are some easy fixes available to resolve the issue.

In this post, we will show you two ways to solve the Windows Modules Installer Worker high CPU usage issue.

Task Manager Disk 100% Usage on Windows 10 (Solved)

Information about Windows Modules Installer Worker

Also known as Tiworker.exe, Windows Modules Installer Worker is not a malware or virus as thought by many users. In fact, it is an important Windows update service that looks for new updates and installs them in your Windows 10 system.

If you have been checking for updates, it is more likely you will see the Windows Modules Installer Worker in the processes column in Task Manager. The process is related to Windows update process and it is started automatically.

How to fix the Windows Modules Installer Worker high CPU usage issue?

Here, we have provided you with two solutions. You need not try both of them. You can start with the Solution One and if it doesn’t work, go ahead and perform the steps in Solution Two.

Solution One – Change Windows update process to manual mode

This solution has worked for many users and it might also work for you. In most cases, Windows 10 is set to update automatically and this results in activation of the Windows Modules Installer Worker service.

By changing the windows update process to manual mode, you prevent activation of the Windows Modules Installer Worker service and the high CPU usage issue is fixed. Here are the steps to follow.

Press Windows key and R on the keyboard at the same time to bring up the Run command
In the Run command box, type services.msc and click OK

In Services window, look for windows modular installer service and double-click on it

In the windows modular installer properties window, go to Startup Type section and select Manual from the drop-down list

Click Apply followed by OK
Go to the Services window again and this time double-click windows update

In the windows update properties window, go to Startup Type section and select Manual from drop-down list

Now open Task Manager and go to the Processes tab, you should see the CPU usage return to normal now. If you still see high CPU usage in the Processes window, you need to try Solution Two.

If you see the CPU usage is normal, it indicates high CPU usage of windows modules installer worker has been resolved. But to prevent Windows 10 to download updates automatically, you need to perform some additional steps.

Case 1 -Using Wi-Fi

If you are using Wi-Fi, perform the steps given below

Click Start and click Settings
In Settings window, click Network & Internet
In the Network & Internet window, click Wi-Fi -> Advanced Options

Click Set as metered connection toggle switch to On position

Case 2 – Using Ethernet connection

If you are using Ethernet (cable) connection, perform the steps given below

Press Windows key and R on the keyboard together to bring up the Run command
In the Run command box, type regedit and click OK
In user account control pop-up, click Yes
In the registry editor window navigate to the following path
HKEY_LOCAL_MACHINE > SOFTWARE > Microsoft > Windows NT > CurrentVersion > NetworkList > DefaultMediaCost
In the left-hand pane, right-click DefaultMediaCost and select Permissions

Click Add

Type your username in Enter the object names box
Click Check names
Click OK
In the Group or user names, select the username you just added
In the Permissions for < username>, tick the box Allow for Full control

Click Apply and then click OK
Now double-click Ethernet in the right-hand pane

Change the data value to 2
Click Ok
Reboot computer

Now Windows 10 would not download updates automatically which will ensure the Windows Modules installer worker does not hog CPU power and degrade the performance of your system.

Solution Two – Update Drivers

Most of the Windows 10 problems are related to incompatible or corrupt drivers. To keep the windows system optimized for performance, you need to update all drivers for your Windows system. You can update drivers manually or automatically.

Manually updating drivers requires some technical knowledge. To update the driver manually, you need to visit device or hardware manufacturer website to download drivers. You also need to have information about the Windows version and the architecture (32-bit or 64-bit). In manual drivers update, there is always a hidden risk of downloading wrong drivers that might cause problems with your computer.
