So I recently put together a new HTPC and have had trouble from the start. I recieved a bad motherboard from ASUS. After getting a new motherboard everything seemed to be working great until I get to loading a new O.S. Everything post fine, but when I load my O.S disc I get this message. "Reboot and select proper boot device or insert boot media in selected boot device and press a key". I know that my disc is good because I have installed it in my other cpu and it loads fine. Here are my system specs. I have the Asus P6T mother board, Intel I7 920 processor, Corsair Memory TX 850 Watt ATX 12V Power Supply, PNY Technologies XLR8 GeForce GTX 275 896MB GDDR3 PCIe 2.0 Graphics Card, Seagate Technology Barracuda 1.5TB 7,200RPM SATA 3.0Gb/s Hard Drive, Corsair Memory XMS3 6GB DDR3-1600 (PC-12800) CL8 Memory Kit (Three 2GB Memory Modules), Optiarc 2x Blu-Ray DVD-ROM SATA Drive OEM, and a thermaltake DH101 HTPC case. When I go into the Bios it shows both the BluRay drive and the Hard drive as being recognized. I have the boot sequence set to Dvd then to the Hard drive. Any suggestions would be greatly appreciated. Thanks for looking!
