The reboot section of the Select Items to be Installed screen enables you to specify preferred reboot behavior.
To instruct the system to reboot after updates are installed:
If Always is selected, then the system will always be rebooted unless there is a component installation failure. If If Needed is selected, then the system will be rebooted if needed by at least one component unless there is a component installation failure.
To change the delay before reboot or the reboot message, click Reboot Options. The Set Reboot Options screen appears.
NOTE: In Linux, the Reboot Delay time is automatically converted from seconds to minutes. Any value under a full minute, 59 seconds or less, will be rounded to the next minute for Linux.
Make any changes, and click OK.
