VirtualBox will configure your VM to the settings you chose in the Wizard. Now it’s time to customize the VM to make it compatible with Windows 8.
Start by Selecting your Windows 8 VM and Clicking Settings.
Click the System tab on the left then the Motherboard Tab. Check the box Enable IO APIC and Enable absolute pointing device. It should look jus like my screenshot below when done.
Click the Processor Tab and Check the box Enable PAE/NX.
Click the Acceleration Tab and Check the box Enable VT-x/AMD-V if not already selected. If these boxes are greyed out… You’re in trouble. Your CPU does not support hardware virtualization which means you might as well stop.
Click the Display Tab on the left and under the Video tab, I recommend you increase the Video Memory to a minimum of 32MB and Check the box Enable 3D Acceleration.
Click the Storage tab on the left, Click the Empty drive under the IDE Controller and Click the Disk Icon.
Note: If your not installing your Windows 8 VM from an ISO but instead using a DVD, Skip this Step and Click OK to save your config. Then Start your VM shown several screenshots below.
Click Choose a virtual CD/DVD disk file…
Navigate to where you saved the Windows 8 .ISO file. Select it then Click Open
All done! Click OK to save all your config changes.
Now it’s time to Start your VM. Click the VM and Click Start
A warning might pop, telling you about Auto capture keyboard etc… All this means is while the VM is running, you will need to press the Right-Ctrl key to release the keyboard and mouse for your host PC. blah blah blah…
By default, a few screens will pop letting you know things are working.
