Windows Server 2008 R2 as Guest, Problem with resolution

[shailwx]

Hello All,
I have just installed VB 4.0.0 on Windows 7 Ultimate x64 edition. My machine is HP EliteBook 8530w with NVIDIA Quadro graphic card. I want to use it for SharePoint 2010. Now I have installed Windows Server 2008 R2 as Guest OS.

I am facing two problems.
1. I am getting resolution 1600 X 1200 which is not covering all my screen. And because of that I have two black margins when I am working in guest OS. I have checked the device manager and it says that I have standard VGA adapter. How I can update driver, I tried to find one for NVIDIA driver for Windows server 2008 R2, but there is no as such driver.
My Windows 7 native OS has a resolution of 1920 X 1200.

2. Mouse pointer behaves like it is drunk. And some strange jumps. I tried to change its settings but no relief.

Can anybody help for any of these points ?

Install the guest additions (in the guest)

Sorry I am very new to it

Thanks
I figured it out. Now resolution and mouse are both OK.

Thank you so much. I wish that I will have a great experience from VB

For future reference, you have a users manual that was included when you install VirtualBox. Pressing F1 in the main VBox program or while in the guest clicking help will show you everything you need to know/learn.
