I again turn to the Techspot community to save my ***. I am currently running a two drive IDE set up, not RAID. I have my OS and a few programs on my 100 GB primary drive, and a secondary 250 GB drive that has a few more programs and storage on it. I only have two bays for hard drives, so I removed my secondary drive and put my SATA in. I have a modular power supply, so I plugged in the cord for SATA power and off we went. When I turned on my computer, I was taken to set up because the Mobo didn't recognize a primary drive, only the SATA drive. Of course, I can't boot because the mobo won't recognize my IDE 100 GB. I unplugged everything and plugged it back in, only to have the same problem. Does the mobo not like my secondary drive being gone? I've been looking for answers online and can't come up with any advice. Should I just ghost my IDEs to an external, put in SATA, then recover my 100 GB OS drive? I'd be happy to provide any more info if needed..
