See: Delay the Boot Sequence in the vSphere Documentation for more information. (Even though the Asker is using Fusion, this Question's visibility is such that solutions for other VMWare implementations seem appropriate.) The version of ESX should be similar to the version of your physical ESXi, access to which must be restored.
NOTE: If your boot device and virtual hardware configuration support it, changing the Firmware setting from BIOS to EFI (requires powering-off the VM first) is advantageous in that it allows for one-time boot device selection, whereas BIOS does not with the BIOS firmware, it's necessary to re-order the boot devices and save the changes, which is in no way ideal because if you forget to disconnect the drive or unmount the media, the VM could boot into the BIOS the next time it restarts unexpectedly, leaving a production machine unreachable until someone intervenes. First, deploy a VM and install ESXi on that VM.
When the BIOS screen comes up, press F2 to enter the BIOS Setup menu. After completing the installation, please unplug the U disk in time to avoid entering the USB boot again.
Select a Windows system and an user, and then click. To change virtual machine options, log into vSphere Web Client. Press F10 to save configuration changes and hit Enter to choose Yes and exit. Changing the VM name doesn’t change the names of the VM directory or the VM files. Select Boot by key and move CD-ROM Drive to the first order by + key as the BIOS Setup Utility interface appears. If the number of hosts is small or manageable, its possible to. Select VM, point at Power and hit Power On to BIOS, as the following screen shot shows. However, any ordering set before the host is moved into the cluster seems to stick. Enabling HA and DRS seems to disable the Virtual Machine Startup and Shutdown options on the host servers.
Your selection will be forgotten the next time you boot up this virtual machine. There doesnt seem to be a clean way to fully manage a cold start of a virtual infrastructure once HA is configured on the individual hosts.
