Troubleshooting system startup failure
If you boot the system to the BIOS boot mode after installing an operating system from the UEFI 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.
