I recently built a new PC with the following specs: 790i Ultra SLI mobo Intel Core 2 Q6700 2GB OCZ DDR3 2000mhz memory 2 x GeForce 8800 GS GPUs and have been getting a black screen after I load the windows vista installation CD. I have pulled my memory to check if thats the issue as well as tried to install Windows XP pro and I replaced the HDD to no avail. Currend BIOS settings are on default so im not sure what the issue could be. Occasionally when I load the Windows XP disk after the setup files are installed the system will restart and instead of going to a blank black screen it will give me a "NTLDR is missing" error. Any advice?
Motherboard should be fine, NTLDR means the OS is missing some necessary boot files, you can fix the the master boot record but I doubt that is your problem. Are your hd connected correctly?? Is your bios detecting the hard drive?? Is hard drive boot order set correctly??
