Delaying the boot operation is useful when you change BIOS or EFI settings such as the boot order. For example, you can change the BIOS or EFI settings to force a virtual machine to boot from a CD-ROM.
- Verify that vSphere Client is logged in to a vCenter Server.
- Verify that you have access to at least one virtual machine in the inventory.
- Verify that you have privileges to edit boot options for the virtual machine.
- Right-click a virtual machine in the inventory and select Edit Settings.
- Click VM Options tab and expand Boot Options.
- In the Boot Delay section, select the time in milliseconds to delay the boot operation.
- (Optional) In the Force setup section, select whether to force entry into the BIOS or EFI setup screen the next time the virtual machine boots.
- (Optional) In the Failed Boot Recovery section, select whether the virtual machine should reboot after a boot failure and enter the time in seconds.
- Click OK.
