Honestly I feel like crying hear. I've just sat hear and asked Google all night a load of questions and I'm dammed if I can get Virtual Box to Install or run a Guest OS.
I'm trying to make a bootable image file to boot VB off the DVD and I'm still no further forward.
I've tried downloading various .ISO files. Disk image files. Creating, deleting ISO's downloading 32 and 64 Bit Os's and mounting and mounting and enabling PAE.
I been in my BIOS looking at VT-x and Hyperthreading. Been to about a dozen web sites looking for information and I'm just stumped on how to progress.
Am really getting sick hear.
Are you trying to run VirtualBox without an OS? ie boot into it like you would an operating system? Or am I misunderstanding this?
If you want something free and relatively easy to use, ProxMox is a great (free and open source) hypervisor.
