I purchased the GPT Loader, downloaded and installed the GPT Disk Manager. Rebooted and put the GPT as my secondary drive. When I have started windows xp back up GPT Disk Manager takes me to the screen to convert HD, partitioning, etc but in my computer or computer management I see no drive. In command prompt before I installed this tool I could run disk part and list the disks and see the GPT but now it does not show up when listing the disks.
