If the server is able to boot normally u can restart using "shutdown /r /o" to access boot menu on next boot.

This is applicable on Windows 2012 and above

This....this needs to be addressed! There are issues with some versions of the VertIO drivers that really seem to host a migrated guest. Really hard to try and get into safe mode when it hangs on boot and your only option is to magically time it just right and manage an F8.

A dated (now) article, but so far I've not seen the option in AHV to boot into BIOS:

As of AHV 20170830.184, don't see the option (yet):

vm.update_boot_device boot_device_order=k
kCdrom kDisk kNetwork

I have just been looking into the same issue and managed to find a work around. The scrrenshot attached it the server booting into Safe Mode with networking as a Sophos patch borked it from booting. Just follow these steps: -

  1. Launch console to the VM in a separate window
  2. Power cycle the VM (you will get a small window with an error)
  3. Press F5 to refresh the window and you should see the BIOS/UEFI screen (as you would if you delayed bootup in VMWare)
  4. Press F8 to get the Windows boot options screen
Let me know if this works, Simon.
