I built a new box with the bare essentials. MB with onboard video, CPU, RAM Single IDE harddrive, SATA DVDRW drive. Put in my Win7 install DVD and started installation. Win7 could not find the hard drive. I then tried an old WinXP installation CD. That got me a BSOD. Then I tried "MaxBlast" since it was a Maxtor drive. The program said the Hard Drive was failing. So I switched to another Hard drive(partitioned and formatted on another PC). Now all I get when I boot is "NTLDR is missing....press Ctrl-Alt-Del to Restart" I never get to my CDROM drive and the installation disk. Checked bios and priority is set to CDROM first, second & third. If I disconnect the Hard Drive, the CD installation starts but no hard drive to install to. Tried a 3rd drive that was cleaned and formatted with the same results. How do I get around this error and install an OS? There is nothing on the drive so I should not need NTLDR yet. I am at a lost on how to solve this error.
