Windows 7: New custom built computer, getting missing driver warning during insta

New custom built computer, getting missing driver warning during insta

I put together a custom build last Thursday, tried to get it to work with Ubuntu however the hardware is too new for it at the moment (it couldn't even pick up the sound chip on my motherboard) so I have purchased windows 7 professional 64bit in the interim. I have used Microsoft's usb tool for installing the operating system as I do not have an optical drive, just USB ports.

this is the hardware, the only thing that has changed is the cpu cooler and power supply: Intel Core i7-6700K, MSI GeForce GTX 750 Ti, Fractal Design Define S w/Window - System Build - PCPartPicker United Kingdom

unfortunately when I try and install the OS from the usb drive, the "select the driver to be installed" section comes up blank and throws up a "load driver" error message exactly like the person in:"A required CD/DVD drive device driver is missing..."

much help is appreciated! i'm at my wits end with this thing now.

This is a known issue and likely affects any attempt at installing Windows 7 on any Z170 motherboard, using USB ports rather than PS/2.

Look through the first page of these Google hits.

The short story is that USB ports won't work during the Windows 7 install, so you don't have a mouse and keyboard.

How to get around it?

Use a PS2 mouse and keyboard.

Or don't use Win 7.

Or use a workaround provided by your motherboard maker, which is likely a BIOS/UEFI setting.

Asrock, for instance, has a UEFI setting called "PS/2 simulator". When enabled, this will allow you to use USB mouse and keyboard as if they were PS/2. This is what you'd do if you were installing from DVD.

If you are using a USB flash drive, I think Asrock wants you to slipstream some drivers into an ISO and then get the ISO on a bootable flash drive.

I don't know how well it works.

Here's some Asrock related links that may give you some insight even though you have Asus:

I don't know what workarounds other board manufacturers have.

All I can suggest is to pound on Google, forums, and your board manufacturer's support sites.

Report back on what you learn, particularly from Asus.

I think this will become a significant issue and I'm surprised I haven't heard more complaining so far. Maybe most Z170 users are not on Win 7?
