I am having an issue upgrading a server from Windows 2000 Server to Windows 2003 Server. The issue is that when trying the upgrade we get as far as installing devices then it blue screens to a "driver mismanages PTE" error. Okay then we tried to do a fresh install and after the reboot before setup begins we get another blue screen "unmountable boot drive" error. The server has a 3 - 160 GB raid 5 stripe configuration. All updates are in place and drivers have been updated. We have been fighting this for 3 days and I don't know what else to do. I need suggestions.
