Just installed win 7 64 bit on XPS 420 quad core 2.4 gh, 8 gigs ram, 1tb hdd. I went to add the old hdd as a 2nd hdd. win 7 won't see old hdd with vista 32 bit. I went into bios, drives are set up for raid, when I turn raid off and re-boot, it won't boot and restarts. Read that I have to reinstall and setup win 7 again. Is this true? No way to reconfigure to use 2nd hdd as storage drive, I don't need the vista for dual boot. Any help would be appreciated. Thank you in advance.
