I'm thinking about migrating from Windows 7 Ultimate 64 bit to Windows 10 Pro 64 bit.

I believe I have 2 options available to me.

  • Do a clean install of Windows 7 Ultimate 64 bit with retail key, then do an upgrade to Windows 10 Pro 64 bit.

  • Do a Windows 10 Pro 64 bit install using the above retail key.

Between the two options above: which process would be the better option of the two or does it not make any difference?

Before a decision is made to give an answer to the question above take into consideration the following:

I plan to wipe my hard drive completely meaning that I do not intend to just delete the partition or format the drive. I plan on using a boot-able disk image partition program to erase the drive fully (write all 0s). Then I want to install Windows 10. I plan on shifting from the standard bios of Windows NTSC to EUFI type bios and partition types if possible.

Once my hard drive is wiped clean and I begin to install Windows 10 I want to know which of the above approaches is better for a good solid clean build of Windows 10. Install Windows 7 first then upgrade? Or Install Windows 10 directly using the Windows 7 retail key? Or what is the correct procedure before I decide to begin the process of wiping my drive?

If you need more information about my current hardware do not hesitate to ask and I will provide it if needed.

Neither option can be used to upgrade to Windows 10 unless you previously installed Windows 10 on the machine. The original free upgrade offer expired back in July 2016 and was extended to users who were using assistance programs until December 2017.

You will need to purchase a Windows 10 license key in order to accomplish what you want.

If you had previously activated Windows 10 on the machine, then either approach would have worked exactly the same, but neither approach is a viable option at this current time.

There isn't an incorrect procedure. If you use the first method, you will have to change the product key, in order to activate Windows 10. The second method is the simplest provided you already have a Windows 10 license. The resulting outcome of either method will be exactly the same.

Given that your comment indicates that you aren't interested in any licensing issues, but purely about the effects of upgrading vs new install here's my answer.

When you upgrade, you keep your files in tact, but you refresh the windows 10 subsystem. Given that Windows 10 is a new OS, it will be like a fresh install, then add all your programs to it.

If you use every single program you have currently installed, and a fresh install will have all these programs installed afterwards, upgrading is definitely the way to go.

If you have many programs installed that you don't use anymore, you can consider to uninstall those before upgrading, or do a completely new, fresh install.

Device drivers will in most cases not be moved over to the new installation, but installed fresh, unless the drivers come with specific software. In some cases, the software is copied, in other cases, its completely gone and needs to be installed. In either case, drivers should not be the reason to choose between upgrading or doing a clean install.
