I had to work all day to get Windows 10.  Started out , VGA monitor would start flickering making it impossible to work.Tech Support was unavailable on Sunday but called me on Monday. By then i had it running. Bought it to run Ubuntu and if possible dual boot with Win10 Pro.  Having trouble installing Ubuntu because Win10 Pro has a twist that makes partitioning tricky. I think something to do with UEFI.  Got help on Ubuntu website.
