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 Web 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.
