Enter Bios Settings and Boot From CDROM With VMware Fusion

| Comments

Today I encountered some problems when I wanted to boot from a pmagic ISO (CDROM) with VMware Fusion: How do you enforce to enter BIOS settings on next boot?

There seems to be no option to do that from the GUI, but this web site helped me to get back on the track: http://raamdev.com/accessing-the-vmware-fusion-bios

For those settings you need to edit the .vmx file of your virtual machine directly.

  • Locate your virtual machine’s location (i.e. ~/Documents/Virtual\ Machines/WinXP/Windows XP Professional.vmwarevm)
  • Right click the .vmwarevm fiel and “show package content”
  • Open the .vmx file in a text editor (i.e. mate¬†Windows XP Professional.vmx)
  • Add the setting bios.forceSetupOnce = “TRUE” at the end of the file


bios.forceSetupOnce = “TRUE” helped to enter the BIOS settings at boot time but strange enough the boot order options settings within the BIOS where locked. I ended up adding the setting bios.bootOrder = “CDROM”, which sets the CDROM as the first boot option within the .vmx file.
