I have clonecd installed aswell which gives me the elbycdio interface so I can try that. The raid is not turned on in the bios, but probably I used the wrong ms drivers.
Since Lightning said something about AHCI, I tried the AHCI raid drivers from MS... but I should probably look further to which drivers I should use instead of the nvidia ones.
Offcourse I could start with a clean install and see what happens then.
