Windows 10 doesn't boot up after GPT to MBR conversion.

My laptop (Win 10 pro) with GPT SSD packed up, so I want to use it in my other laptop that doesn't support GPT.

I used Easeus Partition Maker to convert it from GPT, however it was done on another PC that has GPT and running another Win 10 home. After completing the conversion I ran fixmbr using the same tool. I also set the partition with the OS active via command prompt.

Plugged in the Ssd to the older laptop, but windows didn't boot up, instead I got a white blank screen with an underline on the top left hand corner. It doesn’t respond (only beeps) to any key press except the off button.

Attached is the picture of partitions on both MBR and converted SSD.

Please help, what do I have to do next to make the converted SSD work, if you have done something similar.

Do I need to create 3 partitions like the original MBR disk: i.e. System Reserved, OS and Recovery? is there any other things I need to do?

I am unable to add the picture unfortunately, no idea why. I am using my mobile phone to post this. I will try adding it later if needed.

Thank you.
