I installed Windows 10 on my laptop a few weeks ago, only to discover that the laptop in question is not compatible with Windows 10 which unfortunately Microsoft forgot to mention when I was offered the free upgrade. I have now done a factory reset to return the computer to Windows 7, but I now have two new issues. First, when I switch it on I get a screen asking if I'd rather boot up using Windows 7 or Windows 10. Can anyone advise as to how I can get rid of all traces of Windows 10 from the computer? I just want it to automatically load Windows 7, as it did before I did the upgrade. Second, when I go into windows 7 I am getting lots of "low memory" error messages due to the recovery disk partition which has been imposed on the hardrive. When I look in "My Computer" I see "C: Recovery" with no memory left, and "D: OS" with loads of unused memory. This partition was not present before I did the factory reset, and I'd like to get rid of it and go back to how the computer was set up before. Can anyone advise me on how to solve these two problems? Thanks very much.
