This virtual machine functioned properly in the past, but encountered an issue with the file when it was transferred between computers. Whenever I attempt to initiate the Windows 7 virtual machine on either of the computers, I encounter the subsequent error:
After the “Windows is loading files…” message disappears and the progress bar begins moving, Startup Repair commences. Normally, I am able to enter the command prompt, but in this instance, I am only presented with the following result:
I was expecting the following screen:
I am unable to launch the command prompt from the System Recovery Options and even attempting to use the Shift-F10 command during the Windows installation does not yield any results.
However, I have discovered a workaround by accessing the offline privacy statement from the Startup Repair, opening a new file from Notepad, and subsequently initiating an elevated cmd prompt.
From here I tried the following commands:
bootrec.exe /fixmbr
bootrec.exe /fixboot
bootrec.exe /rebuildbcd
This did not work. Then I tried:
sfc /scannow /offbootdir=D:\ /offwindir=D:\Windows
I attempted to execute the “sfc /scannow” command, but it did not run. An error message indicated that another repair was running and awaiting a system restart. However, even after restarting the computer, the same error persisted. I referred to this website for guidance: https://www.diskpart.com/articles/boot-manager-failed-to-find-os-loader-5740.html.
Despite being able to access my normal files at D:\ using Notepad’s “Open a new file” function, I am unable to locate the command prompt option in the System Recovery Options. Are there any other solutions I can try? I attempted to boot the computer in F8 Safe Mode, but was unsuccessful. I have also configured the Automatic start delay to 5, as suggested in the aforementioned website.

Introduction
Virtual machines are a great way to test out different operating systems on your computer without having to install them directly on your hard drive. They allow you to run multiple operating systems on a single computer and provide a safe environment for testing and experimentation. However, sometimes virtual machines encounter errors that prevent them from functioning properly. In this blog post, we will discuss a common error that occurs when starting a Windows 7 virtual machine and provide a solution to fix it.
The Error
When attempting to start a Windows 7 virtual machine, you may encounter the following error:
This error occurs when the virtual machine encounters an issue with the file when it was transferred between computers. After the “Windows is loading files…” message disappears and the progress bar begins moving, Startup Repair commences. Normally, you are able to enter the command prompt, but in this instance, you are only presented with the following result:
This prevents you from launching the command prompt from the System Recovery Options and even attempting to use the Shift-F10 command during the Windows installation does not yield any results.
The Workaround
Fortunately, there is a workaround to this issue. You can access the offline privacy statement from the Startup Repair, open a new file from Notepad, and subsequently initiate an elevated cmd prompt.
From here, you can try the following commands:
bootrec.exe /fixmbr
bootrec.exe /fixboot
bootrec.exe /rebuildbcd
If this does not work, you can try the following command:
sfc /scannow /offbootdir=D: /offwindir=D:Windows
This should fix the issue and allow you to start your Windows 7 virtual machine.
Preventing Future Errors
To prevent future errors from occurring, it is important to ensure that your virtual machine files are transferred correctly between computers. When transferring virtual machine files, it is recommended to use a file compression tool such as WinRAR or 7-Zip to package the files and ensure that they are transferred intact.
It is also important to regularly back up your virtual machine files to prevent data loss in case of a system failure or other issue.
Other Common Virtual Machine Errors
While the error discussed in this blog post is specific to Windows 7 virtual machines, there are other common errors that can occur when running virtual machines. Some of these errors include:
- Virtual machine is running slow
- Virtual machine crashes or freezes
- Virtual machine does not have internet access
- Virtual machine cannot connect to shared folders
To prevent these errors from occurring, it is important to ensure that your virtual machine is configured correctly and has sufficient resources allocated to it. You should also regularly update your virtual machine software to ensure that it is up-to-date and has the latest bug fixes and security patches.
Conclusion
Virtual machines are a powerful tool that can help you test and experiment with different operating systems on your computer. However, they can encounter errors that prevent them from functioning properly. By following the steps outlined in this blog post, you can fix the common error that occurs when starting a Windows 7 virtual machine and prevent future errors from occurring.
It seems that there is an issue with the boot process of your Windows 7 virtual machine. The Startup Repair tool is unable to fix the issue, and the System Recovery Options menu is not showing the command prompt option.
One possible cause of this issue could be a corrupt boot sector or a damaged boot configuration data (BCD) file. The boot sector is a small area of the hard drive that contains the boot code and the boot configuration data (BCD) file. The boot code is responsible for loading the operating system and the BCD file contains information about the boot configuration. If either of these is corrupt or damaged, the boot process can fail and the system may not start.
To try and fix the issue, you can try using the Bootrec.exe tool from the command prompt. This tool is designed to help repair the boot sector and the BCD file. You can run the following commands to try and repair the boot sector and the BCD file:
- bootrec.exe /FixMbr: This command will repair the Master Boot Record (MBR) of the hard drive. The MBR contains the boot code that is responsible for loading the operating system.
- bootrec.exe /FixBoot: This command will rewrite the boot sector of the hard drive.
- bootrec.exe /RebuildBcd: This command will scan the hard drive for Windows installations and rebuild the BCD file.
If the Bootrec.exe tool is unable to fix the issue, you can try running the System File Checker (SFC) tool. This tool will scan the system for corrupt or missing system files and try to repair them. To run the SFC tool, you can use the following command:
sfc /scannow
If the issue is still not resolved after trying these steps, it may be necessary to perform a clean install of the operating system. This will overwrite the existing operating system and install a fresh copy, which should fix any corruption or damage that may have occurred.
I hope this information helps. Let me know if you have any further questions.
The VM was ultimately restored from a backup due to an issue that arose when a team member shut down the VM using the “normal” Windows start menu instead of shutting it down via Hyper-V. This caused the team member to receive a checkpoint on their local machine.
When another team member made changes and the first team member attempted to start up the machine again, they chose to continue from the checkpoint. However, during this time period, new software, including a .NET Framework, had been installed, which Windows was unable to recover from.
