I have a z77 motherboard and there isn't a working version of the RST software for windows 10.
So, can you create a RAID1 from a disk with existing Data by dos gui(CTRL+I) or not?
It is possible to create a RAID 1 from the control-I menu; however, it is necessary to re-install OS from scratch. It is necessary to back your information first. DOS GUI is not available.
