In BOIS there is a mode RIAD
an array is built for the system in RAID 0
I load the installation with bootable USB-flash and the installer does not see any disk except for USB storage, how to put Win7?
AMD Ryzen 7 1800X AM4
ASUS PRIME X370-PRO, AM4, AMD X370
DDR4 2x16Gb 3000MHz Corsair
I don't believe that Microsoft supports Ryzen CPU's under Windows 7.
