I checked the specs of your MB and it does have a UEFI BIOS. I would make sure you have it set it UEFI mode.
It looks like you have the OS already installed on the drive. Technically it's best to do a clean install on a GPT disk after deleting all partitions and initializing the disk as GPT.
See page 2-8 of your manual. Make sure Windows 8 feature under settings is enabled. This is UEFI mode. Changing this may keep your system from booting. I would also disable both fastboot settings until after the OS is installed.
Are you willing to reinstall the OS? If so then I would do the following after backing up all your personal data and software licenses.
Boot your Windows 10 install media. At the screen that asks for language.press Shift + F10 to open a command prompt. Type the following commands.
select disk X X will be 0 if you have only one drive
clean deletes all current partitions.
convert GPT Initializes the disk as GPT
exit exit out of diskpart
exit exit out of command prompt
continue with the install
