After upgrading my power supply, I get the following error message when trying to boot into Windows 7.

DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER

My Windows 7 installation is on a SATA hard drive.

I'm able to fix this problem if I hook up my IDE hard drive, then it boots the SATA hard drive fine.

I don't like this solution though because then that means my IDE hard drive is drawing power even though it isn't being used.

Why would a newer power supply need the IDE hard drive hooked up just to boot into the SATA hard drive? There are no boot files on the IDE hard drive; it is completely empty. My old power supply did not need it hooked up in order to boot the SATA hard drive.
