Lenovo Thinkstation p700 dual xeons [problem]

[PAOK1926]

hello all,
trying to setup macos on a Lenovo Thinkstation p700 with dual xeons.
i followed the guide, but..

when it boots, i can only see a hard disk with a previous attempt, shutdown/restart options and no option to install os.
i tried tahoma, sonoma, ventura, the same..

can someone take a look why it does not "see" the installer ?
i made the usb in many ways, latest with opencore legacy patcher,with many OSes, latest Tahoe...
