Hi, thanks for answer.
Then i think or SSD have a damaged block on a special sector like GPT instruction or like boot instruction, or boot fail after meltdown patch with Lenovo Bios Win10 driver and SSD firmware not upgrade, or i do not know what happen.
I found a solution.
I have erased all SSD partition with computer manager and after with Diskpart from prompt create a new GPT boot record for the SSD.
Use SSD like this have everytime UEFI bug (inside InsydeH20 Bios with UEFI option SSD not appear, appear only with legacy).
Install WIN10 on GPT SSD with Legacy cant be maked for an unknow error of WIN10 setup (with Legacy boot on Bios can be make only with MBR SSD) that cant be installed with GPT.
Then i make a MBR SSD and installed win10, entry on it, download with media tool WIN10 into ISO file (download to make an USB pen setup do not work).
After use WinToUsb to make with my WIN10.ISO a UEFI bootable USB pen that make win10 setup.
Erase SSD partition, also cached, make GPT with Diskpart.
At restart in Bios i have changed boot from SSD Sandisk to my USB Pen with UEFI WIn10 setup (my USB pen is a 8GB Sandisk ^_^‘’), the with UEFI make by WinToUSB software is bootable also with UEFI option and AHCI on my Bios.
Then is start the WIN10 setup and with UEFI and AHCI set on Bios, WIN10 can be installed into Sandisk SSD with GPT partition.
After this i can upgrade Bios and SSD firmware…
