If you ever have trouble getting into the BIOS of a VM, this will help. Before booting the VM, edit the corresponding .vmx file and modify the following setting.
bios.bootDelay '' boot delay in milliseconds
This will give you more time to press F2 to get into BIOS (usually I just need to get in to set the boot order)
