Installing Ubuntu 9.10 on an encrypted disk

Installing Ubuntu 9.10 on an encrypted disk

Is it possible to install Ubuntu on a laptop running Windows XP on an encrypted disk? My company encrypts all laptops before distributing them. When I try to install Ubuntu the installer reports that there is no OS on the system, since it cannot see the data on the HD. I cannot of course choose the whole disk for installation nor partition it since it will possibly screw up my XP installation. Is there any way around this?
