Very strange situation. I built a new system with new hard drive which turned out to be faulty so I installed Windows 7 on my old 500Gb hard drive. A couple days later I bought a new WD 1TB SATA drive and installed it into my case. I installed Windows 7 on it but forgot to unplug my old hard drive. Now both drives have to be plugged in in order to boot. If I unplug the old hd it get error message "Reboot and select proper boot device or insert boot media in selected Boot device and press a key" when I boot from the new hd. Bios is set properly with the WD 1TB drive as first boot drive and dvd as second and is set as AHCI. What could be the problem? I want the old hd out of the case. Also, upon boot a black screen with white text asks me to select the OS I want to boot and gives 2 options, Windows 7 or Windows 7. One is linked to old drive and 1 to new drive.

Nope, do the clean install with only the new drive with no other HDDs or SSDs attached, select a custom install and as a first step delete all existing partitions, then install to the remaining single unpartitioned space.

Your system reserved partition and bootloader are on the old drive, I would try booting the system with just the new drive and the installation disk inserted in the optical drive to do a system repair, which should solve the problem (if you are lucky, and it seems to work most of the time).

If all else fails, you can always do a clean installation to the new drive with no other HDDs or SSDs attached, which will force the SRP onto the new boot drive.

I've tried that but when it asks to select an operating system to repair there is nothing in the box to select. Is there a way to copy the srp files from the old hard drive and copy to the new one. If not, I'll do a fresh install. (Fingers crossed....I only have one install available. Disk came with 3 installs and I've used 2)
