I have built a new Windows Server 2008 R2 X64 server on an HP Proliant DL380 G4 server. When I tried to install a Sata Raid controller for an external HDD, I got a system halt. I removed the Sata Controller, but now when Windows boots, it gives me a System Recovery Option dialog box and wants a recovery disk. This is a brand new server and I don't have a recovery disk made yet. At one point I was able to get the server to boot using Last Know Good. I removed the offending driver and rebooted, but got the System Recovery option again. This time it won't let me past it with a Last know good or safe mode. Is it doomed to just have to be rebuilt from scratch?
