Problem with Raid on asus Board

[STIGABONZAA]

Yesterday i tried out a raid 0 setup for the first time. took some effort but finally it worked and a problem has occurred.

I have 2 Samsung SSD's. One 830 Pro(128gb) and a 840 pro (120gb) (not ideal i know but suited my needs and cost). That is in a raid zero array from the ASUS motherboard controller and works perfectly after a bit of tinkering. The problem is that now my HDD with games, music, university work are now not being recognized in the BIOS.or disc manager. I think that this is because the BIOS is set to read raid arrays but if i switch the BIOS to IDE the system will not boot.

Might be a simple error on my part. it may not be-able be run a RAID and non raid setup of the ASUS controller . Any help is greatly appreciated and apologies if this is in the wrong section.

Many thanks
