Here's the deal as a web developer I am total rookie in the hardware stuff, but since we make more money now and tried to experiment some stuff.
I got this Raid1 (4 SAS Drives) and extra 3TB Sata drive (it has some broken windows on it).
I installed my debian on the raid1 while the SATA drive was plugged out. When I plugged it in it took advantage in boot order because the Raid is never displayed in the bios menu.
My question is how to fix the boot order, so the raid would be loaded first and after that the SATA as simple storage device ?
