IIUC you can't do a clean install the first time. You have to "upgrade" first, because MS checks your Win 7 license info. Then after Win 10 is first installed you can THEN perform a second, clean install.
Amazingly enough I just now downloaded a new Win 10 update which patches core Sandy Bridge processors.

My Dell Latitude e6420 laptop runs Windows 10 just fine. But it has an i5 Sandy Bridge processor, not a i3 Sandy Bridge like yours. Original ship date December 2012. I added another 4 GB of RAM to give it 8 GB total. Win 10 ran better with the increased RAM.
Sandy Bridge is a 2nd gen. core...
