Troubleshooting appliance startup failure
If you boot the appliance to the BIOS boot mode after installing an operating system from the UEFI Boot Manager, the appliance 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
: By default, set this appliance to BIOS boot mode.
