Installing 10?

Just make sure the boot manager (bios) is set to boot from an EFI device - MBR boot will not work on an EFI HDD

You have selected the correct EFI CD/DVD Boot Option.
When booting Windows install DVD select the EFI option if given.

You need one of the latest AHCI SATA drivers. The OnChip SATA Type [Native IDE] is incorrect option for your large hard drive. Native IDE operating systems are Windows XP/2000. You nee to select [AHCI].

You probably should add the latest AMD AHCI driver for Windows 10. I do not know if the Windows 10 library already has the driver.

AMD Chipset Drivers
Supports Windows 10/8.1/7 (64​-bit)
Package Includes:
AMD Chipset Drivers
AMD AHCI Driver
http://support.amd.com/en-us/download/chipset?os=Windows+10+-+64

After downloading the package, click on the file and extract it to a New Folder. Cancel any Installer that pops up.
Then go thru the folders in package and find the "Windows 10 64-bit AHCI Folder" and direct your Windows 10 installer to that folder at the beginning of the installation when you have a chance to add drivers. The installer is looking for a FOLDER not a file. You can put the folder on a little USB 2.0 flash drive in advance.
