SN68SG2

Q. Why can't I install the Windows OS when use SATA optical disk drive with SN68 series?

This is a known issue of Nvidia chipset, if you want to install windows OS with SATA ODD, please change the SATA setting form IDE to AHCI in BIOS->Intergrated Peripherals->MCP Storage Config->SATA Operation Mode, then install windows.
