VBox Windows7 SP1 question

I have Vbox 4.0.4_OSE installed on my 11.4/KDE4.7 Laptop with Win7 and WinXP VMs installed.
Generally runs well, although the Win7 VM seems to lock up on occasion if I ignore it for too long.
Compared to having to reboot to Win7 to do the few things still stuck on Windoze, it is a GREAT solution.

Question: I have seen several forum items related to difficulty with dual boot systems and the installation of Win7SP1, regarding SP1s checking the MBR for the Win7 boot loader. Has anyone done a SP1 update to a VM on Vbox? It is sort of unclear what SP1 might see in the VM disk container associated with the VM.

Since the initial load process for a new VM is time consuming, I thought I would ask first before blowing up my otherwise working Vbox system and then having to reload from scratch.

Thanks in advance for comments.

If you installed Windows 7 from scratch (not from an image already created) without a problem, surely the Service Pack would also install properly in the same session. Windows seems to want to have a standard MBR and to be the active partition. In this simulated disk world, it should think everything is OK. Normally, it does not hurt to try and install the Service Pack. If it starts, but then does not like what it sees, it will just abort with no harm. Any time a Service Pack loads, I suppose there is a chance it might mess up your Windows install, but that is a different issue and not very normal to occur.

Thank You,

Thanks for the encouragement.
The first attempt hung, I killed and restarted the VM, Windows recovered itself and second attempt was successful.
