I have here a DL360 G5 server.
Windows 2003 Server R2 installed. Server has been historically troublefree. Uninstalled AV and rebooted, but it wont come back up!
Server finds and initialises RAID (P400i) as per normal. Finds the logical drive.
At the point at which it normally shows the boot screen it just lists the boot order (CD, USB, HDD, NIC) and tried to then boot from NIC which of course is unsuccessful.
Checked boot controller order - RAID Card is before IDE channels.
Pressed F10 for System Diagnostics (CPU/RAM/Boot Disk) and all pass. Boot disk passes on all 3, including valid OS boot sector.
I had this with my own VMWare Server not booting to a USB Key, which I fixed in the end by powering off completely then restarting.
I have tried several power cycles (power leads out) and still nothing.
This Server is the one and only DC so nothing works with this off!!
