Win7 pro SP1

I am trying to install Win10 from the ISO disk of August15, on top of
my existing system, but the upgrade seems to have stalled on the
"Getting Updates", "Checking for updates" window, with the little
balls going round & round & round & round...
So far this has been going on for 20 minutes; should I backstep and
skip this "get Updates" option?

What I've noticed here, is the installer logic may
be trying to acquire a video card driver, before the
installation starts.

If your system didn't have a Windows 10 video driver,
that might be a gating item.

Too bad the installer didn't admit to what it
was doing, as status messages help users a lot
when they are provided.

Also, to acquire updates, you might need a
working BITS subsystem. If your Windows Update
was previously 100% functional, then you know
the rails are greased for acquiring downloads.

Using MediaCreationTool today, *freshly downloaded*,
should cause a later version of the OS to be downloaded
for you to make a DVD or whatever. So perhaps
one copy of MediaCreationTool will fetch 10240,
while one you downloaded today will fetch 10586
or 11082 or whatever Microsoft wants you to have.

That won't, though, solve the video card driver
problem. The installer should still make preparatory
"driver fetches" before it starts. I don't get the
impression they want to install the OS using just
the VESA fallback driver. I think in Windows 8
you could do that (that's how I got some Win8
Preview to install on my FX5200 card that didn't
have a driver - card runs 1024x768 with no
acceleration to speak of).
