Not recognized in Vista

Just rebuilt my machine with an AMD 5000 Black Edition and ASUS M2R32-MVP. I have two Hds, a WD 74GB Raptor and a WD 160GB set-up as JBOD (same as my last config). When I boot, the system tries to load Vista(from my previous install), then restarts. I tried to repair it, but it still doesn't work. I may have screwed up the MBR. The drives show up in the BIOS, but when I try to install Vista(and XP), they are not recognized. When I load the drivers in set-up, it then tells me there are no hard drives installed, so, I can not install a new copy of Windows on my drives. I used my Western Digital disc to try to do something, but it doesn't recognize the drives either. Any suggestions? Thanks

OK, I have an update. I went into the BIOS and changed from SATA to IDE. That allowed me to load VISTA onto my first drive. But.... now VISTA won't recognize my second (SATA) drive. I can make it appear, but it says it is RAW and needs to be formatted. I have all of my old data on that drive. I did access it in DOS, but cannot in VISTA. Any help?
