Hi I just updated the latest bios and it seems like secure boot is enabled by default, it was not in 3102. Additionally there is CSM stuff that has had also different default settings, additionally the new updated added 3 new sub-settings below CSM. I will start researching what to set to proceed to install win7 in uefi mode. In the meantime thank you for suggestions, especially how to disable secure boot, doesn't seem to be able to do it from that screen. So for boot from disk should i choose UEFI only or Both ?
