I was running windows on an IDE hard drive and bought a new SATA and installed a fresh copy of windows on it, now having a dual boot with the old installation on the IDE. I've been running on the SATA drive for a few months now and I want to remove the IDE drive from my system but when I disconnect it and reboot I get a message that tells me NTLDR is missing so I am assuming that the boot record is on the IDE drive. How can I make the SATA drive my main boot drive?
