Over the weekend someone attempted to upgrade Windows Server 2003 to 2008 on one of our machines. Not sure what happened, but it didn't work and now when booting up after the little green bars, the screen goes black, there is a white cursor, and nothing ever happens. If I start in SafeMode, I get some kind of "Cannot complete installation in SafeMode, please restart" error, so nothing doing there.
I figured I'd try a fresh install, but I cannot get either a CD with the ISO or a bootable USB flashdrive to work. I have tested both the CD & flashdrive on another machine and they work fine. On this machine, if I try to boot it from the boot order it says no bootable media found, if I try to directly boot from a boot menu, the USB drive method gets stuck with a blinking cursor and nothing happens, while the CD will take me to a 'Start Windows in SafeMode` prompt. I tried to boot a linux disc to rule out the CD drive and that worked fine. Any ideas?
