yeah thanks for all the help i did it in the end. if anyone has got a giga byte ga-k8n pro sli motherboard, or the ga-k8n ultra sli. you have to get the drivers for the sata/raid on the cd that came with the motherboard i know its stupid because how can you install the cd without the o/s. instead you have to get a floppy and install the drivers on the floppy. if you go into the cd open the folder BootDRV and then open the MENU.exe select E and it will extract it to your floppy, and when you install windows again press f6 and install the drivers
