I set up two VMs with win8.1 as guest in LL2.4 host:ġst one: guest installed in normal Legacy mode, USB 3.0 connectivity works fine (using v.5 of VBox), so extension pack installed, and file sharing with host, and guest takes up full-screen, so guest additions installed too. A few more details about what I did exactly just to clarify - sorry I was a bit sketchy with initial details of the Oracle VirtualBox set-ups I'd created. Many thanks for your interest and comments Wirezfree. Open the VM settings, select System, and on the Motherboard tab, select Enable EFI (special OSes only). However, if you'd still like to test or use EFI with other operating systems, enabling EFI support is easy. It supports EFI too, but unfortunately does not support booting UEFI-based system volumes, which includes Windows 8 in UEFI mode. VirtualBoxVirtualBox by default uses the BIOS firmware for virtual machines.

While Mac OS X and Linux guests are known to work fine, Windows guests are currently unable to boot with the VirtualBox EFI implementation. Note that the VirtualBox EFI support is experimental and will be enhanced as EFI matures and becomes more widespread. Googling xxx finds lots of stuff even pre VBox 5.0, like
Oracle vm virtualbox extension pack 5.0 install#
I'm going to return to a standard VM install of win8.1 on LL host for now, which seems to tick all the boxes for my present needs. My curiosity was piqued by a UEFI VM, but is now satisfied. So it seems early days for UEFI for windows in VBox, at least for me.
Subsequent reboots just resulted in the VM freezing. I went through the procedure recommended by a win8.1, specifically for installation of this patch, using windows command line, but to no avail. This meant I avoided the UEFI Interactive Shell entirely.Īll went very well, following this, until one of the security patches (around 700MB) refused to install. It's during the subsequent reboot that I got stuck at the UEFI Interactive Shell screen.įollowing this, I reinstalled win8.1 as a VM in UEFI mode but, this time before I shut it down following installation, I installed the guest additions right away. The mistake I made when I first installed win8.1 in VirtualBox was to shut the shut the machine down, following installation, and then trying to install the guest additions in the subsequent reboot. Thanks Wirezfree - I haven't looked at the links you gave me just yet - to update you.
