New BIOS options for new boards are kinda complicated to me. Obviously CSM has to be enabled. 2 additional settings pop when it's enabled: Storage boot options control: - Legacy (I've read if this was chosen, AHCI wouldn't work?) - UEFI (UEFI in CSM? Whaat?) Other PCI Device - Legacy - UEFI Q1: What the hell is going on here? Isn't CSM legacy itself? Can I have CSM on and still have UEFI enabled for these? Also, If CSM is enabled then there will be 2 boot options for THE SAME drive, like: - DVD-RW - UEFI: DVD-RW Q2: You must boot from NON-UEFI option according to Daz Loader's Readme. Is that right? The loader doesn't work when the systems using GPT. The workaround is to pre-format your hard drive so that it uses MBR instead. From your BIOS select to boot the Windows DVD without UEFI, press and hold SHIFT and then press F10 and then enter this: diskpart list disk select disk 0 clean convert mbr create partition primary select partition 1 format fs=ntfs quick Boot the Windows DVD the same way you did the first time.
