When you run a virtual machine (VM) on VMware Player, the default boot sequence of the VM is
removable devices →
hard drive →
CD-ROM drive. If you want to boot a VM from an ISO image instead, you need to change the boot sequence of the VM, so that it starts with CD-ROM drive.
In this article, I will describe how to change the boot sequence of a guest VM on VMware Player.
As a demonstration, I will set up a guest VM to boot from an ISO image, which requires booting from CD/DVD.
The first step is to edit the CD/DVD setting of a VM. Open up the virtual machine settings of a VM, and edit the CD/DVD setting to connect to the ISO image that you want to boot from.
There are several ways to change the boot sequence of a guest VM on VMware Player.
Simply, power on the guest VM. Right after the VM is powered on, and before power-on self test (POST) starts, click into the VM's console screen, and then press
<F2> button. That will lead you to the guest VM's BIOS settings as shown below.
Boot tab, and press
<down> key to highlight
CD-ROM drive. Press
<+> keys to move
CD-ROM drive up on top.
Save the change, and exit the BIOS settings.
Upon exit, the guest VM will boot from the ISO image loaded on CD-ROM drive.
If you cannot press
<F2> button quickly enough to enter BIOS settings, add the following entry to the
*.vmx file of the guest VM.
bios.bootDelay = "<number_of_milliseconds>"
This will delay POST procedure. Note that the unit of numbers is milliseconds. So if you want to delay POST screen by 5 seconds, it should be:
bios.bootDelay = "5000". The maximum allowable boot delay is
10000 milliseconds or 10 seconds. With additional boot delay, you will have more time before booting, during which you can press
<F2> key to enter the BIOS setup menu.
Alternatively, you can add the following entry in the
*.vmx file of the guest VM. This will force the guest VM to automatically enter the BIOS settings upon power-on.
bios.forceSetupOnce = "TRUE"
bios.forceSetupOnce will automatically be reset to
.vmx file after successful booting. So the next time you power on the VM, it will not re-enter the BIOS setting. If you want to re-enter the BIOS setting, you will have to edit
.vmx file, and set
"TRUE" manually again.
