Upgrading to Win 8 should not be an issue. I am sure Dell's recommendation is based on driver (provided by them) support, or the lack thereof. This is a fairly "generic" system, so Win 8 will likely have driver support built-in for nearly all of your devices.
Have you run the Win 8 Upgrade Assistant on your system?http://windows.microsoft.com/en-US/windows-8/upgrade-to-windows-8
Yes, and I read everything on this thread so I realize that it could be one of a hundred items causing windows 8 to fail to install. I tried Dell and all I got from them was that if I paid $129.00 they would install it for me. I called MS tech support and they said that I would need to buy the Win 8 CD and do a clean install. I suppose they will not refund the money that I paid for the download?
Thanks for the quick reply to my question.
