I have 2 western digital hard drives, a 20GB hard drive with Windows 2000 installed and an 80GB hard drive with windows 2000 installed. When I try to boot the 80GB, it gives the message "ntldr is missing". I've had this problem before, but I don't really remember how I fixed it. Last time, I re-installed Windows 2000 on the 20GB and for some reason, when I tried to boot the 80GB, it worked. I can't figure out why. Sometimes the computer detects the 20GB as bootable and sometimes it detects the 80GB as bootable, depending on the jumper settings, but the 80GB ALWAYS gives the "ntldr is missing" error. I don't know what to do. Both hard drives are detected in BIOS, but they're never both detected as bootable devices when I go to the boot menu. Help..??
