Mouse and keyboard both work in BIOS, but not when booting Windows 7 setup.
New CPUs like Intel Skylake or Braswell do not have USB 2.0 support included. Windows 7 does not have USB 3.0 support included (at least not at setup boot time by default), so this combination cannot work.
For default Windows 7 installation e.g. via boot stick, Zotac recommends:
- Use the Win7 boot stick in the USB 2.0 slot, mouse and keyboard in USB 3.0 (not USB 3.1!). Use an up-to-date Windows image.
- Update BIOS to latest version
- Use the Intel Creator Utilty to make your Windows 7 setup ready for USB 3.0 (it integrates the necessary drivers)
- BIOS: Legacy boot mode
If you use PXE boot services like Microsoft WDS:
- Create a driver package from the drivers subfolder(s) which are delivered with the Intel Creator Utility.
- Modify option of the WDS driver package: “Applicable: All driver packages in this group”
- Assign the package to your WDS Win7 boot image
