Default Boot Device Missing fix?

Hello Rumen, sorry about your problems. My name is Marco and I will do my best to help you.

The error messages you are seeing suggest that the laptop is unable to find a bootable device, which could be due to a misconfiguration in the BIOS/UEFI or a hardware issue with the storage device.

Turn off your laptop completely.

Press the power button to turn on the laptop.

Immediately start pressing the F2 key repeatedly to enter the BIOS setup.

Once you are in the BIOS/UEFI settings:

-Check the boot order to ensure that the internal hard drive or SSD is listed as the first boot device.

-Look for any settings related to storage or SATA configuration and make sure they are set correctly.

-If you see an option to load default settings (often F9), you might want to try that to reset the BIOS settings to their defaults, which can sometimes resolve boot issues.

If the storage device is not listed or if these steps do not resolve the issue, the storage device may have failed or become disconnected. In this case, you may need to contact Lenovo support or consider returning the laptop for service.

 

Unable to boot the PC stuck in WinRE mode

Hi,

Thank you for writing to Microsoft Community Forums.

I understand how difficult it can be when the PC doesn’t work the way it is supposed to. I appreciate your effort in trying to resolve the issue by performing troubleshooting steps. For better understanding of the issue, please
respond to the questions below:

1. Are you aware of any changes being made to the PC?
   
2. Do you receive any error code when you try to boot the PC normally?
   
3. What are the troubleshooting steps you have tried?
   
4. What is the error you receive while performing reset?
   
5. What was the result of automatic repair?
   

Meanwhile, you can try removing any external devices connected to the PC and check if you are able to boot the PC.

However, I would suggest you to follow the steps mentioned below and check if that helps.

Method 1:

I would suggest you to try booting the PC to safe mode and check if that helps.
Refer the article
Start your PC in safe mode in Windows 10. If the PC is working fine in safe mode, perform a clean boot being in safe mode environment check.

Performing a clean boot will start the computer with minimal set of drivers and programs, to determine whether a background program is causing the issue. Some of the Startup programs will not load after performing a clean boot
on the computer. However, that functionality will return when you reset the computer to start normally after finishing the troubleshooting.

To perform a clean boot on the computer refer to the article

How to perform a clean boot in Windows.

Note:
Please refer the section Reset the computer to start normally after clean boot troubleshooting
to boot the computer in to normal mode after troubleshooting.

Method 2:

Try troubleshooting startup issues. You can refer the article on

troubleshooting common startup issues and see if that helps.

Note: While performing chkdsk on the hard drive, if any bad sectors are found on the hard drive then chkdsk tries to repair that sector if any data available on that might be
lost.

If you have an external hard drive, you can take the backup of the data by following the steps mentioned below.

1. Open command prompt window by following the article
   
   troubleshooting common startup issues.
   
2. On the command prompt window type,
   notepad.exe and hit enter.
   
3. Now click on File
   and click Open…
   
4. On the Open file window, click on
   This PC
   
5. Now navigate to the location
   C:\Users\UserName\ select the folder that you want to backup to the external drive.
   
   Note:
   To see all the files on the Open dialog box, change the
   files of type to All files.
   
6. Right click on the file/folder
   and select Send to and select the external hard drive.
   

If the issue persist, please get back to us with the result of troubleshooting steps to assist you further with the issue.
