I am trying to upgrade to Windows 7 64 bit from Vista 64 bit. When I put in the Windows 7 installation disk into the DVD drive and click "Install Now", it goes to a full-screen setup page, which reads: - Setup is copying temporary files... - Setup is starting... - Then an error message pops up which states "Windows could not retrieve information about the disks on this computer." I have tried the to start the Virtual Disk on my computer by going into Services and get the following error: "Windows could not start the virtual disk on Local Computer: Error 3 The system could not find the path specified. Then I started playing around with the Vista Device Manager. I went to my hard drive and clicked on properties and then to the Volumes tab. No data was populated so I clicked the populate button and received the following error: "Volume information for this disk could not be found." I have updated the disk drive to the most recent driver and still have the same error. Any information or help would be greatly appreciated.
