Vbox crashes my whole system

[nemam]

After installing Vbox and guest additions on my Windows XP it request reboot of the system. After the reboot my system cant boot up properly. i.e. after the windows boots up the mouse pointers goes to the left bottom corner of the screen and stays there. When i move the mouse the pointer moves for a second and again goes to the left bottom corner.I can't even click the login name on the boot screen. I try to boot the Windows XP in safe mode and againt the same happens, i even tried to boot in Safe mode with Command prompt, and its also the same. This happened to me 3 times till now, even with different versions of Vbox, and i had to format and reinstall Windows XP. This is the 4th time the same problem appears and i dont want to format again because i'll lose some important work. If it means something for u i have Dell Inspiron 1520 Notebook (Intel Core 2 Duo, 2GB RAM, 120GB WD HDD). PLEASE HELP ME WITH THIS ISUE, IT REALLY IMPORTANT FOR ME. This is my mail address: togenx@… Thanks

I HOPE TO HEAR FROM U.

Have you installed guest additions on your _host_ WindowsXP system (that is on the real computer)?

Yes i did :( , and i shouldn't do that right? I think that after installing the guest additions on the XP host it messes up something with the Mouse and/or keyboard. So is there a way to receover my XP instalation witout formating? I have openSuse installed on other partition so i have access to the partition where Windows is installed.

Right, guest additions must be installed inside the guest.

To restore your XP system you could try to boot to Last Known Good Configuration (press F8 when XP starts to boot).

If this does not work, you could try to boot OpenSuse and then delete \WINDOWS\system32\drivers\VBoxGuest.sys as well as VBoxMouse.sys from the WindowsXP partition. After that XP should boot.

When you have XP running again, I'd recommend to save your work and reinstall XP from scratch to get rid of additions.
