Cannot upgrade the Hyper V windows 10 VM to Windows 11

Question

I have a physical desktop converted to virtual machine. Now I am not able to upgrade to latest OS. I have 4 partitions in the disk. So, whenever I am trying to convert the MBR to GPT, it is getting failed. Disk validation is also getting failed. I am also getting the error "Windows re image was not found"

***Move from Windows / Windows 10 / Install and upgrade***

Hi,

Thank you for reaching out to Microsoft support. I understand that you are having issues upgrading your Hyper-V Windows 10 VM to Windows 11 and encountering errors when trying to convert the MBR to GPT.

To resolve this issue, please try the following steps:

1. Ensure that your Hyper-V host is running Windows 10 version 1903 or later and has the latest updates installed.
2. Check if your VM meets the minimum system requirements for Windows 11. You can refer to this link for the system requirements: https://www.microsoft.com/en-us/windows/windows-11-specifications
3. If your VM meets the system requirements, try creating a new VM with a GPT partition scheme and install Windows 11 on it. You can then migrate your data and applications from the old VM to the new one.
4. If you still want to convert the MBR to GPT, you can try using the MBR2GPT tool provided by Microsoft. You can refer to this link for more information on how to use the tool: https://docs.microsoft.com/en-us/windows/deployment/mbr-to-gpt
5. If the disk validation is failing, you can try running the chkdsk command on the disk to check for any errors. You can open Command Prompt as an administrator and run the command "chkdsk /f /r" to scan and fix any errors on the disk.
