Drive not found (identied).
Cause Solution
Cable could be loose. Check cable connections.
The system may not have automatically recognized a newly
installed device.
See reconguration directions in the Solving hardware installation
problems on page 56 section. If the system still does not
recognize the new device, check to see if the device is listed within
Computer Setup. If it is listed, the probable cause is a driver
problem. If it is not listed, the probable cause is a hardware
problem.
If this is a newly installed drive, run the Computer Setup utility
and try adding a POST delay under Advanced > Boot Options.
The device is attached to a SATA port that has been hidden in
Computer Setup.
Run the Computer Setup utility and ensure Device Available is
selected for the device's SATA port in Advanced > Port Options.
Drive responds slowly immediately after power-up. Run Computer Setup and increase the POST Delay in Advanced >
Boot Options.
Nonsystem disk/NTLDR missing message.
Cause Solution
The system is trying to start from the hard drive but the hard
drive may have been damaged.
▲ Perform Drive Protection System (DPS) testing in system
ROM.
System les missing or not properly installed. 1. Insert bootable media and restart the computer.
2. Boot to the windows installation media and select
the recovery option. If only a restore kit is available, then
select the File Backup Program option, and then restore
the system.
