Hello,

I tried to turn the CSM support off and boot the official Win10 installation flash drive. The official win10 flash drive should be UEFI compatible and is formated by the FAT32 system. But I am not able to boot it.

If I try to install it in CSM mode, it works, but it seems that the OS is also installed in the old BIOS mode, because whenever, after the installation, I try to turn the CSM off, the OS is unable to boot.

I am a bit confused. Do you have any advices?

Thank you.
