So I need to add a extra hard disk for RAID array and try to install ubuntu server again. The hard disk is already detected and the installation was successful. It didnt, but I enabled it by adding acpiosi to boot options like Joerg had done (see the comment above). These instructions are suitable if you wish to keep the Win7 install running alongside Ubuntu.
