XPS 8900 - There was a problem resetting your PC -- Windows 10 install

Hello

This is my first post -- I'm not even close to being expert, but I have been able to try some things from watching Youtube, etc - I am having trouble installing Windows 10 -- I don't mind if I wipe out everything -- a factory reset is fine, (I backed up my files to external drive)

I have a Dell XPS 8900 desktop -- 

I purchased the PC in 2016 with Windows 7 pre-installed. A Windows 7 Pro SP1 64 bit Reinstallation DVD and Windows 10 Pro 64 bit DVD was provided with the purchase, and I still have both discs.

I am able to re-install Windows 7 Pro SP1 successfully, booting from the DVD drive and installing, etc.  And after that, Windows 7 will load normally from normal boot. But, when trying to clean install an upgrade of Windows 10 using the same steps, with the Windows 10 disc, I run into trouble. 

Description of steps:

Boot with Windows 10 re-install DVD 

Choose English, US, etc

Click the options:

          Troubleshoot

          Reset this PC

          Remove everything

Option then says to choose a target operating system

Only option on screen is Windows 7 -- So I click that

Then the options are

          Only the drive where windows is installed

          All drives -- (I choose this)

Then I choose -- Fully clean the drive

Then I click Reset button

It starts the process: 

         Resetting this PC 46%

The process will reach as far as 46% complete or so before it is interrupted by a blue screen with an error message

            There was a problem resetting your PC.                 Cancel

So I just click Cancel and go back to re-install Windows 7. I tried a handful of times to clean install with the Windows 10 DVD and it seems to consistently stop the process around 45%. Wondering what that could be a sign of?

Would it make a difference if I did not use the Windows 10 re-installation DVD that was supplied by Dell when I purchased the PC, and instead, should I try downloading a copy of Windows 10 from the internet and boot with a thumb drive?

Is there a step that I'm missing? Do I maybe have to install some drivers before I attempt to install Windows 10?

Some info from Disk management screen (which I can get when Windows 7 is installed)

Disk 0 (an SSD drive)

  29.82 GB NTFS -- Healthy (Primary Partition)

 (I think Dell initially meant for the SSD to be a cache drive, but maybe it was never setup properly. I just treated it as a place to drag miscellaneous files into.)

Disk 1

System Reserved 100 MB NTFS -- Healthy (System Active

C: 1862.92 GB NTFS Healthy (Boot, Page File, Crash Dump, Primary Partition)

Some notes in case it matters:

The fresh install of Windows 7 knocked out my internet capability.

Does Windows 10 need the internet to complete the install process? 

When installing Windows 7, I was never asked to enter the product key code -- Will this prevent it from working properly? I do have the keys for both Windows 7 and 10 

The Legacy option is chosen in boot menu, if that matters?

I have run the diagnostics test from the boot menu -- it passes all tests. 

Any advice and help would be greatly appreciated
