Hello and good day,
I’m currently running Windows 8 enterprise and I encountered an issue with the Windows 7 Ultimate x64 (vhdx) Hyper-V image I created. Once the image was created and configured I ran SysPrep to create an OOBE and mount the VHDX image to the
student laptops. I encountered the following issue:
Due to .vhdx been a new extension recognized by Windows 8 and Server 2012, when I tried to mount the vhdx to an actual machine it gave a “not able to recognize image” error massage.
I converted the vhdx to vhd using the converter provided by Hyper-V. I tried to mount the vhdx to an actual machine it gave me the same error message.
I did the following steps to mound the vhd to a student laptop:
1. Created a folder called vhd [c:\vhd]
2. Copy ‘StudentOOBE.vhd’ to the vhd folder
3. Rename ‘StudentOOBE.vhd’ to PWStudent.vhd
4. Ran CMD (Admin) and typed the following commands:
bcdedit /copy {current} /d ”PWStudent”
5. There is a GUID that is created. Right click the quid in the command prompt and select ‘Mark’. Highlight the GUID including
the brackets and press enter.
6. Then I typed the following commands:
bcdedit /set { paste guid here } device vhd=[C:]\vhd\PWStudent.vhd
bcdedit /set { paste guid here } osdevice vhd=[C:]\vhd\ PWStudent.vhd
bcdedit /set { paste guid here } detecthal on
7. Press Windows Key + R and type ‘msconfig’ in the run box. Press enter.
8. Click on the ‘Boot’ tab.
9. Click on the Student### thus making it the default OS.
10. Change time out to 5 seconds and click ‘Apply’ and then ‘Ok’.
11. Restart the laptop and run through the OOBE, unfortunately once I restart the laptop it does not recognized the image and I get the “unrecognizable
image” error
Please advice
Thank you
