"Reboot and select proper boot device or insert boot media in selected boot device"
I installed the hard drive and it was recognized by the BIOS at start up but not by windows. I have already installed Windows XP SP2. I disconnected the hdd and attempted to boot from a CD drive but still got the same message. Also same with the floppy drive.
Motherboard: ASUS P5Q Pro
HDD - WD400EB 40GB (Master); WD1600JB 160GB (Slave)
