I'm using VirtualBox to create two virtual windows side-by-side on a single 1920x1080 monitor. Each window is thus 960x1080 minus the VirtualBox window borders.
During Windows bootup, the VirtualBox gets resized to 1024x768. It readjusts to the proper size once Windows is fully booted and waiting for login. Because 1024 is greater than 960, the window on the right half of the screen is shifted left a little bit and I have to manually drag it back into its proper position after every boot.
Is there a way to get Windows to boot at a lower resolution?
