Hello Steve Klein1 and welcome to the Microsoft Community!

Based on your feedback that you are experiencing problems cleaning and recovering Diskpart from MBR/VBR/GPT

First of all, I noticed that the hard disk is infected with a virus.

Therefore, I would recommend that you format it if possible.

If you have a lot of files to keep and don't want to format it

I recommend you to run a full disk scan with antivirus software or windows defender first

to avoid virus infection on your whole computer

Then when it comes to cleaning and recovering MBR (Master Boot Record), VBR (Volume Boot Record) and GPT (GUID Partition Table)

please follow the steps and instructions below.

This process will erase all data on the disk, so make sure you have backed up your important data.

1）Steps to Clean and Recover MBR/VBR/GPT

intend：
- Using Windows 10 installation media (USB or DVD), you can download and create a boot disk from Microsoft's website.
- download link：Download Windows 10
- Navigate to the installation media and select “Repair Computer”.
Enter the command prompt：
- In the Recovery menu, select Troubleshooting > Advanced Options > Command Prompt.
Use Diskpart to clean up the disk:
- Once at the command prompt, enter the following command to start Diskpart：

cmd

diskpart

  4.Then select the destination disk (assuming disk 0)：

cmd

select disk 0

   5.Clean up the disk:

cmd

clean

   6.这将删除所有分区和数据，并清除 MBR/GPT。

   **2）Rebuild MBR/VBR/GPT:**

Click on the windows key + R key, click on CMD, and enter the following command

For MBR:

Enter the following command to rebuild the MBR:

convert mbr

For GPT:

Enter the following command to rebuild the GPT:

convert gpt

Creating partitions and formatting:

After cleanup and conversion, you need to create new partitions:

create partition primary

Then format the partition (assuming the newly created partition is the first):

format fs=ntfs quick

Assign drive letters to partitions:

assign letter=C

Recovering VBR (Volume Boot Record):

VBRs are automatically cleaned up when the disk is cleaned up, and after rebuilding a partition, formatting the partition creates an appropriate VBR.

7.Loading Windows:

If you already have Windows installed, you can use the following command to install the boot manager:

bcdboot C:\Windows /l en-us /s C: /f ALL

Reboot your computer:

Type exit to exit the command prompt, reboot the computer, and check that the new operating system boots properly.

take note of

When doing so, make sure you understand the risk of data loss that may result.
After recovering MBR/VBR/GPT, make sure you reinstall the operating system to prevent any remaining viruses.

If you encounter any problems while executing these commands, please feel free to ask and I'll be happy to help you!

We hope you find the above information helpful
