Troubleshooting system startup failure
If you boot the system to the UEFI boot mode after installing an operating system from the BIOS Boot Manager, the system stops
responding. To avoid this issue, you must boot to the same boot mode in which you installed the operating system.
For all other startup issues, note the system messages that appear on the screen.
NOTE: Dell Storage NX430 NAS system supports BIOS boot mode only
