Windows Boot Manager Loop

Hi Deng Majok

Welcome to Microsoft Community.

Based on your description, I understand that you have a Lenovo T-470, but when you turn on the computer, it automatically goes to startup management and you can't get into Windows, and I understand very well how you feel!

As far as the situation is concerned, it could be due to corrupted system files, hard disk boot error, incorrect BIOS settings, hardware problems, etc.

I will give you some solutions and hopefully solve your problem successfully! However, the first reply may not be able to solve your problem due to the lack of information and the fact that the problem requires different aspects of troubleshooting, so please understand and provide more information in your reply (pictures would be great!). Thank you very much!

Option 1: First some suggestions for types of checks so we can narrow down the problem.

(1) Please go into your BIOS and check if the hard disk where the system is installed can be detected.

(2) Check to see if the first place in the boot sequence is the hard disk where you installed the system.

(3) If you have multiple memory sticks in your laptop, try unplugging one and booting. Repeat this until all memory sticks have been individually tested by us and are working properly.

Option 2: After troubleshooting some hardware issues, we tried to repair the system from the command line. This step requires us to enter the “WinRE” environment first.

Please follow the steps below to enter WinRE:

(1) Press and hold the power button for 10 seconds to turn off your device.

(2) Press the power button again to turn on your device.

(3) Immediately after seeing Windows start up (e.g., some devices display the manufacturer's logo on reboot), press and hold 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 reboots, press and hold the Power button for 10 seconds to turn off your device.

(6) Press the Power button again to turn on your device.

(7) This time, allow the device to fully boot up.

(8) Select Troubleshooting.

(9) Select Advanced Options.

In “Advanced Options”, select “Command Prompt” -> Please execute the following commands in sequence

(1) Execute the command to scan and repair the system first

DISM /Online /Cleanup-Image /ScanHealth

DISM /Online /Cleanup-Image /CheckHealth

DISM /Online /Cleanup-Image /RestoreHealth

SFC /Scannow

Please note: The above scanning commands need to be executed 5-6 times to ensure the completeness of the scanning!

(2) Repair Windows boot from the command line again

bootrec /fixmbr

bootrec /fixboot

bootrec /scanos

bootrec /rebuildbcd

Option 3: Please try to make an external Windows installation media for repairing Windows system.

Please note: Please choose an external storage device that does not store important data, such as USB flash drive, removable hard disk, etc., to avoid losing your data!

To make a Windows installation media you can refer to: Create installation media for Windows - Microsoft Support

The system repair steps are:

(1) First, create Windows installation media

(2) Connect the created installation media to the computer

(3) Start the computer and set the Windows installation media as the first place in the BIOS.

(4) Save and enter, the computer will enter the Windows installation program

(5) Click Next, and then click “Repair Computer” in the lower left corner.

(6) On the “Choose an option page”, click “Troubleshooting”.

(7) “Advanced Options”

(8) “Start Repair”

I sincerely hope that the above solution will solve your problem. Please feel free to contact me if you have any problems or still can't solve them. (Photos related to the question would be great!).

I look forward to hearing back from you. 

Best Regards

I have a photo (a video if it would allow me)

That's just a regular legacy boot selection. Does at least one of the entries take you to Windows?

Thank you for your response.

But unfortunately this is just a screen of the startup options and it is not possible to derive more information from this photo. It is also consistent with what Dear Volume Z expressed.

(1) May I ask what results did you get or what problems did you encounter after trying the solution?

Especially Option 2 and Option 3 in the first reply, because Option 2 can scan and repair the system and the system's boot startup from the command line. Option 3 is more effective in repairing the system by comparing the image with the external Windows installation media.

(2) If you can record a full video, you can upload the video to Youtube or cloud drive, and then attach the sharing link in your reply, thank you very much!

For now though, I'd like to know the results of your attempt at the solution in your first reply so we can narrow down the problem.

Whenever I click the ESC key, it just keeps taking me back to that screen.

Thank you for your reply.

Thank you again for the detailed video.

Allow me to explain to you that the screen you are currently on is a Windows boot startup screen. Currently it is asking you to pick one of the two Windows 10 and click enter as the choice.

If you click ESC, it is to cancel the boot. After canceling the boot, the computer will automatically reboot and come back to this Windows Boot Manager page over and over again.

So please try selecting the first Windows 10 and then the second Windows 10 to see if both are able to enter the system, one is available and one is not, or neither is able to enter the system.

If it is convenient for you, you can try to record a video of entering the system to see if you can enter the system successfully or you will be forced to enter WinRE.

Please note: In general, one of the two Windows 10 options will allow you to enter the system without any problems. You can subsequently just boot into the system by selecting this Windows 10 that can enter the system.

Sincerely hope that my statement above is clear enough!

Looking forward to your reply!

Best Regards

Thanks as always for the video info, I really appreciate it!

The feedback from the video seems to confirm what I suspected in my first reply.

Because there are several scenarios (including the one guessed in the first reply) where we select the system to enter from the Boot Manage screen, but repeatedly return to this screen:

1, the system boot corruption, because when the Windows boot corruption, we enter Windows every time due to the inability to boot into the eventual return to the selection interface

2, memory corruption, which is why there is a memory detection option in the selection interface.

Please allow me to explain to you that the principle of memory detection is to access the data repeatedly to see if there is a bad point situation.

If the memory is corrupted or there are bad dots, it will also cause us to load the system to a certain situation, and then suddenly can not be loaded, and finally back to this interface.

3, system file corruption, system file corruption can also lead to the system loaded to a certain extent can not load the situation occurs.

Have you tried some of the solutions in my first reply? The solutions in my first reply can perform troubleshooting, detection or repair for these situations.

(1) Windows boot and Windows system files, I gave you some command lines to try to fix.

(2) The reason for making an external Windows media is that we can't repair the Windows boot and system files from the command line anymore. At this point, we perform a comparison repair through the Windows image file eventually enabling us to complete the repair successfully.

(3) For the memory stick detection, you can go through what I suggested in my first reply as our current laptop will have multiple memory sticks. In this case, assuming that the memory sticks are damaged, it is unlikely that all of them will be damaged, so we can try to remove the other memory sticks and keep only one to see if we can get into the system without any problems. And so on, eventually testing all the memory sticks.

Personally, I would recommend that you try Option 2 and Option 3 first to rule out a system-caused cause, and then finally try Option 1 to troubleshoot a hardware cause.

In addition to testing all memory sticks by removing them from the hardware, you can also perform the Memory Test in the Options screen. But you need to wait for some time, which may be longer. A report will be presented for clarification after complete detection.

Looking forward to your good news! You can be assured that you will follow the steps I have given you, and I have tested these options through one of my own personal Asus computers!

Could you possibly make a tutorial on how to do all 3 steps?
