I'm working on a Dell PowerEdge 2850. The primary partition was on the F drive and needs to be on the C drive. I used regedit.exe to change it and now the computer won't boot. When I type in my user name and password it shuts down. I tried repairing and reinstalling Server 2003 but it does not see any HDD's. Their is nothing that needs to be saved on it. What can I do?
