So... as the title implies I am Trying to Install Win 7 Pro (32bit) over Win XP on a Toshiba Satellite P200-RT1 Laptop. When I begin the install it eventually pops up " Windows could not retrieve information about disks on this computer" . Most people suggest ..."This error usually can occur because the VDS is set to disabled. To resolve it, you need to enable the “Virtual Disk” service." The problem is when I run SERVICES.MSC Virtual Disk Service isn't listed anywhere, so then people suggest to run devmgmt.msc, expand the drives, go to Properties, Volumes Tab & click "Populate" then Insert the Windows 7 installation disc and launch Setup.exe. Still I get the same error (Even when I dont click ok in the volumes Tab and leave it up)... Is there something I'm Missing or is there another possibility for this issue? Thanks in advance to anyone who can help shed some light here!
