Upgrading to Win10 from Win7; fails every time with 0xc1900101-0x30018

Hi All.

I am a Mac user, but bought a PC on craigslist, that had windows Windows 7 on it. I am trying to upgrade it to Windows 10 and it is failing every time. I have downloaded the update package and installed that way and it fails at 32% of total install, approx 12% of installing drivers and features. I have done quite a bit of reading on the subject so i have tried the following:

-removed all unnecessary hardware
-rolled back drivers
-update to newest drivers
-removed antivirus
-removed all aftermarket software
-attempted upgrade by installing via flash drive and by disc

there are probably others that i cannot recall in my frustration.

i have read about a video card causing issues. The mobo does not have onboard video and this machine has a GeForce 8600 GTS SLI, without the 2nd card installed.

not sure if it is worth buying a cheap card to install to see if that is the issue...

i am sure i will recall other specifics once we start some conversation here, but i would greatly appreciate your help. My intent is to donate this machine so i want to ensure it is working properly so i do not have to offer free tech advice in the future that i am not qualified to give.

Thanks in advance and Happy Holidays

System File Checker indicates that there are some corrupt system files, but this is way above my head so i wouldn't know how to correct them.

i will post the log here when i can.

I ran SFC as Admin and tried to open the log and it opens notepad and says Access Denied. Never had that issue before...

I copied the final to another location and managed to move it to my mac and post it here.

Since it is 21 pages of text, what is the best way to share it here?
