connection and power cables are securely connected to the hard drive. On this

of this guide for connection details.

drive connector damage on the drive or in the chassis.
Reseat the hard drive and its carrier in the chassis to be sure that there is
a proper connection. (See the Hard drive section of this guide for

Boot Order Incorrect Run Computer Setup (F10) Utility and set the correct order in Advanced >
Boot Options > UEFI Boot Order and Legacy Boot Order. If drives are
removed and the system rebooted, the boot order may be changed by the
BIOS and would need to be reset to the desired order. The F9 Boot Order
menu can be used to check and choose the right drive for boot.
Verify that the drive is listed in the Computer Setup (F10) Utility
(Advanced > Boot Options > UEFI Boot Order or Legacy Boot
Order). NOTE: Drives only appear in UEFI Boot Order if they contain a
folder named EFI at the root of the drive. If it is listed, the probable
cause is a driver problem. If it is not listed, the probable cause is a
hardware problem.
