On the Guest Operating system / VM (Virtual machine) in VMWare Workstation , if you want to go to BIOS setting menu or want to set boot priority, etc, by pressing ESC key, F2 key, etc, usually you will not be able to reach it, because the process is too fast.
To be able to enter Bios setting,You can do by setting delay time before the system launch the operating system
You must set the Configuration file (vmx file) of the Virtual Machine.
Open VMX file using Notepad then add the following code:
bios.bootdelay = "5000" and then Save it.
Example below, adding bios.bootdelay = "5000" to the Windows 7 VM.
Run Notepad, and open the Vmx file of the VM (browse to the VM Location Folder)
|Open VMX file of the VM Guest using Notepad|
bios.bootdelay = "5000"
Save the file and run the VM.
