Unable to install Win7 from USB on Lenovo Z70-80 (Broadwell-U)

[jakson]

I can't install Win7 x64 SP1 on notebook Lenovo Z70-80 from USB 2.0 pendrive.

I was trying USB 2.0 ports and USB 3.0 port with no success.

Than I integrated latest intel USB 3.0 and storage drivers into boot.wim and install.wim using DISM tool and there is still no success - the installer can't find Windows 7 installation pendrive. There are disk partitions and mounted boot.wim in drop-down list, but even USB mouse doesn't work.

PS I'm sure that it is USB issue - not storage. I added storage drivers "just in case".
PS2 I'm sure that USB 3.0 and storage drivers are correct.

It looks like Windows 7 can't even see USB 2.0 ports.
Any ideas?

Hi Jakson,
from what ive found that Lappy came with W8, you will have to change the Bios settings to boot W7.

Have a read of this tutorial.
