Hello everyone!
2 days ago I bought Lenovo y700 laptop without cd/dvd drive thus I was forced to install Win7 via bootable USB stick. I've encountered some issues but now I'm stuck at this common problem of "driver missing". Just to say, as for now nothing has worked, changing USB ports, configuring BIOS...
Win7 works fine on friend's PC
changing USB ports does not work - after getting the error I press cancel, go back to the first 'install' screen and after I switch to another port the flash drive is not working (the light is not flashing) until i restart the laptop
also there is not many available options for configuring BIOS (I don't have any disabling USB 3.0, changing to IDE, AHCI whatever
I've downloaded f6flpy-x86 file which I thought may do the job but the main issue here is that when I click browse for selecting the driver from directory I only see this: http://imgur.com/GRBvvmr
Even though the flash drive is working I can't see it there to install those damn drivers. I'm sitting here like an idiot for two straight days and can't find the solution for this shieet. I'm asking for your help, hope someone knows how to solve this :(
 
Solution
if this helps any ?? [gets same error warning as you ]

Microsoft is removing support for the EHCI host controller (USB 2.0 spec) and keeping only the xHCI host controller spec (also known as the universal USB 3.0 specification). While the USB 3.0 spec is backward compatible with most USB 2.0 and 1.0 functions, installing windows 7 via USB will not be one of them (source: EXPReview).

I thought it was just for skylake but it may be any usb install now ??

theres a tool some manufactures got to insert the removed driver during install to got over the as a work around

[click on the 100 series tab and see ??]...

i don't read russian so i can't translate your error image.

but, it appears you may need the OEM version of Windows specifically for this device.
formatting the HD and doing a fresh install should boot fine using Microsoft's default drivers unless Lenovo is using some custom Windows package.
maybe try Windows 10 install via USB instead of 7 for updated drivers.

sorry it's in polish, but it basically says "A required CD/DVD drive device driver is missing", and when i click "browse" to select a file directory for this driver it can't read my flash drive although it is working properly. Unfortunately I don't have any other copy of Windows and I need to make this thing work til the end of this week so I am forced to find a solution with what I got :(

there are downloadable versions of Windows 10 iso from MS specifically for USB install. use this system your typing on to download and create the install media.

https://www.microsoft.com/en-us/software-download/windows10

could be worth a shot
