I'm a student and my university has a subscription to Dreamspark, so I got a Win10 key, along with an ISO-file from there. I'm using a Lenovo G700 and trying to perform a clean install from a bootable USB-stick.
I have tried creating this USB-stick with the "Win7 USB DVD Download Tool", using different guides from the internet with NTFS and Fat32 filesystem, launching the setup normally and through UEFI, using the "Media Creation Tool" (http://www.microsoft.com/en-us/software-download/windows10) to create the USB-stick directly and downloading the ISO file first and creating a bootable USB-stick from that with all the methods above, but no matter which of these methods I use, I get the following error during installation:
"A media driver your computer needs is missing." (http://oi60.tinypic.com/2n1weuq.jpg)
Unfortunatley, I am currently running Win7 Pro x64 on my laptop and the following page says, that the upgrade to Win10 only works from Win8.1, not Win7: https://support.lenovo.com/sg/en/documents/ht103535#lenovonotebook
When I try to use the "Media Creation Tool" to instantly perform an upgrade, I get the following error:
"Something happened... 0x80070422 - 0x90016"
What drivers could the installation possibly be missing? I don't have any external devices plugged in, except for the bootable USB-stick, of course. I tried downloading all drivers for Win7 x64 and Win10 x64 from the Lenovo page (http://support.lenovo.com/sg/en/products/laptops-and-netbooks/lenovo-g-series-laptops/lenovo-g700-no... and pointing the setup to them, but none of them help.

I used Windows Update to install all available updates, but I am not getting the little icon in the system tray. I am guessing that this is because the Lenovo G700 can't upgrade from Win7 to Win10 directly, as it clearly says so on this page: https://support.lenovo.com/sg/en/documents/ht103535#lenovonotebook
I don't really want to perform an upgrade, I want to perform a clean install, but neither works right now.

It may involve some drivers neccessary for the system to operate, but they are not available for Windows 10 yet and thus the media failure message.
I can not pull up your system online from the US of A - says the URL is blocked. Not sure about this, but will try to view a local G700 for more information.
In the mean time - I would suggest calling Lenovo support directly and speak with a rep about this issue. They may have a work around in place that we can not see on the support page.

But all the drivers are available for download from the linked Lenovo page from the OP and the upgrade works fine from Win8.1 (at least the Lenovo page says so), so I don't think that any drivers necessary for the system to operate under Win10 are not yet available^^.
