What you are trying to accomplish is a dual boot, usually Windows needs to be installed first before Linux, creating a NTFS partition when formatting.
Our recommendation is contacting the Linux authorized support groups for further information and instructions on how to create a dual boot system using these two Operating System (OS).
both systems are installed an running very well.
Windows on P0 and
Linux on P1.
What settings do I need in BIOS to always boot from P1?
When UEFI is activated, the mainboard always boots from P0!!! WTF #fail
