I've been through the answers to similar questions, but they all require USB or CDROM booting. I've installed EFI - it might be that I've not done that correctly, but it boots in EFI, but doesn't find the CD or a USB stick.
I have got Ubuntu running under VirtualBox on the mac mini. It's just horribly slow.
Is there not some way that I can install bootable Ubuntu onto another partition on the same physical drive, so I can dual boot from the same disc, using Ubuntu on VirtualBox?
I've been hunting, but I can't find any instructions to do this.
I'd be grateful for any pointers.
