I just got Windows XP home edition (upgrade). I currently have windows 98 se. I put the XP cd in and ran setup. At one point I got a message saying "Setup cannot continue. Contact microsoft technical support. (Error: 5C9FF58h)"
You should not need to do that.. simply boot into 98 and run the install process and when it asks if you would like to leave the current file system intact or whether you would like to run a clean install choose clean install.
Yeah, I did that. It begins copying installation files and then reboots. In the middle of the reboot I get a menu asking me to "please choose operating system to start:
Microsoft Windows XP Setup"
If I choose windows it loads 98 and then nothing happens. If I choose windows xp setup I get a blue screen which starts copying more files. After that I get a C prompt in some recovery thing which says I can type exit to exit and reboot. If I do that the system reboots and I end up back at the choose operating system to start screen.
