I was referred to this item on Amazon by Carey Holzman a computer tech I know. So I bought one for my kids and grand kids. It arrived on time and in good condition. How ever when i first turn it on it would not boot, said no OS installed. It was to have win 10 pro on it. Check hard drive found win 7 only. Got it to boot with win 7 and did a win 10 update from Micro soft and all ok after update of OS and drivers. So the info on Amazon is not always correct. Let  the tech support know of problem they responded promptly and offered to help but i had already corrected to problem. Thanks Amazon and the tech support dept.
