Windows 10 Spare drive with second operating system. Is this OK?


New Member
I have an old portfolio management program on my PC. I have upgraded to a new PC and tried to migrate the program to the new PC using Easeus Todo. The program migrated OK but will not run on the new PC and I get an error message that " The registration has been tampered with. The serial number does not match this hard disk". The program was a software download and I am unable to buy a new license for the new PC. I know I can clone the hard drive from the old PC to the new PC and the program will probably work. However I do not want to do this as the old operating system (Windows 10 home) is bloated from years of updates etc. and my new PC has a fresh install of Windows 10 pro. I have already migrated all the files and folders I want to keep. Can I transfer the old hard drive to the new PC and use it solely to run my accounting program as well as have some extra storage? Or will the old OS cause conflicts with the new one? Thanks in advance for any help. P.S. I do know how to use the bios to set the boot priority.
Transferring your old hard drive to your new PC and using it solely to run your accounting program while also having extra storage is definitely a viable option. However, there are a few factors to consider regarding compatibility and potential conflicts.

1. Hardware Compatibility: Ensure that the old hard drive is physically compatible with the new PC. Check the connector type (e.g., SATA, IDE) and the available connections on your new motherboard.

2. Operating System Compatibility: Booting from the old drive could potentially cause conflicts if the old drive's operating system is not compatible with the new hardware. Your old operating system, Windows 10 Home, may have drivers and configurations tied specifically to your old PC's hardware. This could lead to instability or issues with driver conflicts when running on the new PC. While it is possible for the old OS to work on the new PC, it may require additional troubleshooting and potential driver updates.

3. Licensing: If you continue using the old hard drive, the Windows license tied to that OS may not be valid for your new PC. Windows licenses are generally tied to specific hardware configurations, so you may need to purchase a new license for Windows 10 Pro on your new PC.

Given these considerations, I would suggest an alternative approach:

1. Clean Install: Install a fresh copy of Windows 10 Pro on your new PC. This will ensure that your new operating system is clean and optimized for the new hardware.

2. Virtual Machine: Set up a virtual machine on your new PC using virtualization software such as VMware or VirtualBox. You can then install Windows 10 Home on the virtual machine, allowing you to run your old portfolio management program within that virtualized environment. This isolates the old operating system from your new one, reducing the risk of conflicts and allowing you to use your program without affecting the new PC's stability.

By using a virtual machine, you can preserve the functionality of your old portfolio management program while enjoying the benefits of a clean and updated Windows 10 Pro installation on your new PC.

Please note that using a virtual machine does require some technical knowledge, and there may be performance implications depending on your system's hardware specifications.
Thanks GPT for the quick reply. And thanks also for suggesting a virtual machine as a possible solution. After some reading I am hoping it may be possible for me to use Hyper V with a cloned image of my old PC's hard drive to run my portfolio manager. Do you think that is a viable solution? And if so could you suggest a tutorial on how to effectively install my old PC complete into the virtual machine on my new PC? Thanks.
Thanks to all responders. I spent a whole day yesterday configuring a Virtual machine on my new PC. After many fails I finally stumbled on the right configuration steps and now have a VM clone of my old PC up and running perfectly on my new computer. A lot of effort but worthwhile in the end. So happy. Thanks again.
