I recently purchased a new dell xps 8900. My old unit a Dell Dimension 4700C runs on the discontinued Windows XP. I ran the Windows 7 Upgrade Advisor on the 4700c and the advisor says the machine will run Windows 7. I purchased a WIN PRO 7 SP1 X32 EN OEI NO CN DVD LCP from Dell online - $140 or so. I put the cd into the dvd/cd-rw drive (D). Nothing happens. The little indicator light on the drive door lights for a second and then it goes out. I have an external LG brand drive, dvd-ram drive (E) connected. When I attempt to run the disk from this drive, the indicator light flashes for 30 seconds or so but nothing happens. When I double click the drive, the error message says Please insert a disk into the drive E:. ??
Additionally, when setting up the xps 8900, I had to create the installation media on a thumb drive. I was fixing the windows 10 which Dell had said was included with that purchase. That installation was eventually successful. Again, I downloaded installation media for Windows 7 to a removable drive. It is an .iso file about 2.5 g. It too unfortunately does nothing when I attempt to run it from any usb port.
Any advice you can give is greatly appreciated.
Thank you.
