Not able to select VMware worksation bios set up. The delay at boot is too little to select the bios To increase the delay edit the .vmx file and add an entry like bios.bootDelay = "10000" . This will make system wait 10 seconds 

This method describes doing it in Linux guest virtual machine, there is another method from host using vmware-vdiskmanager. In the guest where you are trying to shrink, make sure VMware Tools is already installed. To get vmware toolbox (which has many options including shrink) run vmware-toolbox ex: vmware-toolbox          or /usr/bin/vmware-toolbox run this command as root otherwise shrink option will not be enabled. this will open a new window with shrink option, you can select the partitions you want to shrink and click on shrink.
