Can't change the screen resolution in XP Guest
Posted: 10. Oct 2014, 02:14
I can't start the guest OS (XP 32bit). From VirtualBox Manager I select Start (I only have one guest). I see the black Oracle VirtualBox window. I see the first black XP startup screen. It freezes on the next Blue XP windows is starting up screen that is way to large.
This started happening when the guest window was too small. Within the guest I changed the resolution to it's maximum.
Now when I am on the Window is starting up screen, selecting View, The Auto-resize Guest Display is greyed out.
The Adjust Window Size doesn't do anything.
The Machine Session Information says Screen Resolution 1600x1200x32
This PC has a maximum screen resolution of 1366x768.
I have tried running this bat file with the guest off.
VirtualBoxSetScreenResolution.bat
It runs fine with no errors:

XP still doesn't start up.
I have also tried running the command with 1024x768.
I noticed after running the command the XML file in C:\Users\Doug\.VirtualBox\VirtualBox.xml
doesn't show any change in ExtraDataItem.
I have tried to add VBoxGuestAdditions.iso
The settings say it's installed.
I don't think it's installed correctly.
