Hey guys im running a completley fine version of Vista 64 but i want to upgrade to Windows 7 64 since i tried it out on my laptop and i preferred it to Vista. Anyway I have 1 Hard Drive split into 2 partitions, one been 70gb - 10gb free space (Windows Vista) and the other is 300gb - 60gb free space (Windows XP) so if needed i can move around some files to create some extra space. I want to upgrade to Windows 7, because i have alot of important software which would take too long to re-install, but whenever i run the setup.exe and select upgrade it runs for a few seconds and the i get the error message: "Windows could not retrieve information about the disks on this computer" and the setup ends, is there a way round this? I checked the Windows 7 Upgrade Advisor and everything was normal in there, however i'll upload the report, to see if you can find any faults. P.S. I've tried 3 different releases now and all of them get the same error. Also tried burning at different speeds, different DVDs and tried installing from a virtual drive, and i still receive the same error. I also tried upgrading from booting the CD, it told me to restart the PC, let it boot into Vista and run setup.exe, which brings me back to my original problem =[ Any suggestions would be great!
