i got nvme0n1 working!!!
first, i did new flash boot usb drive in windows, because i messed around too much somewhere…
then i used the method with 2 usb sticks, as before,
but nvme0n1 got stuck in legacy mode, then i went into volumio as (usb) -reflashed Volumio to nvme from the settings, at the end it did say that it failed, but when shutdown, took the usb out, went to bios, nvm0n1 was now there as uefi mode, started it and its now in nvme0n1 Volumio!!
radio music is playing
i did disable dsp, wlan and Bluetooth again, cause i dont use them.
it literally took like 5-6 sec, and volumio is up and running…
