I have Windows XP Pro SP2+ running on an HP Pavillion 510w. I started getting "operating System Not Found" occasionally. I decide to use Norton Ghost to Ghost a new Maxtor drive. It worked fine, but I screwed up somehow on the bootup and nor my ghosted drive is assigned to F: and is the boot drive. The Maxtor is in master and the old seagate is the slave. They both show when I boot up, but neither will boot up without the other. I went to Disk management under Manage My Computer and thought about changing the drive letters but it won't let me. It says C: seagate is a "Page File" and the Maxtor is the "system" drive. All kinds of weird things are happening. How do I get the new Maxtor to be assigned to C: ??
