SOLVED Windows 10 Install from an OEM disk

[RecumbentTim]

I have had no success in installing Windows 10 as an upgrade to Windows 7 on my newly built system. What I intend to do tomorrow is to install from the OEM disk which I just purchased for $117.14 from A...... I may return the Windows 7 disc ($61) for refund if it is successful. If not the Windows 10 disc goes back for refund and I will keep Windows 7. Yes, they will issue full refund and free return shipping no questions asked. That is an additional $56.14 to acquire Windows 10 (including a disc) but worth it to me
I'd cross my fingers but those from my planet only have one digit per limb. Good when irritated but no help here.

I'd cross my fingers but those from my planet only have one digit per limb

With one on each limb, I think that would still work, maybe an unconventional finger crossing but I think it still counts.

Yes, that works. I just installed Windows 10 with the disk and it was very fast and uneventful. I have customized the installation and it looks and acts perfectly. I will dual boot with Windows 7 later when I get a bigger hard drive but this is perfect.
It is unclear why I could not upgrade to Windows 10 from Windows 7 but I got here the old fashioned way. Finally!
