I've tried many things but my computer will still not boot. I just built my new computer with a Gigabyte DS4 Motherboard, Intel Core 2 Duo E6420 Processor, 2GB RAM, 8800GTS, and a 320GB Seagate drive. When I first booted my computer I had my old 80GB IDE drive in it so I could transfer the files I needed onto my new hard drive. My problem is that once I removed the old drive, my computer now says "DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER." It POSTs fine but will not boot to Windows.
