Here`s a tip for anyone that is failing to get fullscreen mode in your guest OS ie win 7, win 10 etc. I have just installed Win 10 preview, having a 17" laptop and a 1600x900 res I wanted full screen for purebasic.
I came across these solutions for window and linux to add required screen modes
No Virtual Machines Should Be Running and VirtualBox Manager Should Not Be Running!!!!!
Windows: at the Cli
Linux: at the Terminal cd into the users VirtualBox\ VMs/ folder. So vboxmange can find the VM`s Name%ProgramFiles%\Oracle\VirtualBox\VBoxManage” setextradata “Name_Of_Your_VM” CustomVideoMode1 New_Screen_Resolution
/usr/bin/vboxmanage setextradata "Name_Of_Your_VM" CustomVideoMode1 New_Screen_Resolution
Where Name_Of_Your_VM = "Window 10 x64" or "Windows 7 x32" etc Make Sure You Use QuoteMarks for the VM`s Name
Where New_Screen_Resolution = 1600x900x32 or 1920x1280x32 etc
