following your suggestion, the error has changed, now i see error on disk (1). Thank you for your support

Mine has 5 Sata Port, and i will use 4 of them. Sorry, but i can't try the way to edit the grub.cfg file. The tiny micro core, is a weird linux for me

Unfortunately i can't find any similar option My HW is an HP Prodesk 800 G1 with the latest bios avaliable. I have also an internal gumstick ssd, with this adapter https://www.ebay.it/itm/143267697290. Thanks a lot
