Install will not detect hard disk in that mode . If it is feasible , modify BIOS drive setting to AHCI ( or IDE ? ) , otherwise installation is NOT possible in that mode . Another suggestion may be : If it is possible , use an external hard disk . is displaying sd0 as available disk when an external USB HDD is attached just like an internal HDD . This point is very much confusing . I think a warning about specifying - the detected situation about RAID mode - internal HDD(s) is (are) ignored , - external USB HDD detected as ... ( a name different than internal HDD name ) . It is not possible to understand which HDD is detected from the installation message : It is internal HDD or external USB HDD . Assume that external HDD is accidentally connected and contains very valuable data without backup ( NOT a good practice but assume it is like that ) . It will be destroyed without noticing that it is the detected hard disk . Thank you very much . Mehmet Erol Sanliturk
