Okay, so I got an old Windows XP system that has an MB800V-R Motherboard. It only has IDE ports and no newer SATA ports. I need a backup drive in case the original was to fail, so I tried cloning the IDE to a SATA and am unable to boot from the SATA. This is the adapter that I have for converting from SATA to IDE going into the MB800V-R. The PC is able to recognize the SATA drive with the adapter during normal operations, but when I remove the old drive and try to boot from the SATA it just doesn't work. I have tried changing the boot order to USB, didn't work. Plugging the IDE cable into the adapter that goes into the SATA is fruitless as well. Any help or insight would be greatly appreciated!
