Our guess is that at some point the process of mounting the WIM for driver adds had an issue and did not commit and seal correctly, leaving it in this unstable state this was the source of our first headache. While troubleshooting we happened to look into the folder where the boot WIM resides and saw that there were two boot WIMs in this location with odd names. We had already added the Win 8.1 Driver to the WinPE boot image, which is usually all that is needed when you have a newer version of WinPE and are deploying an older OS. We verified, using the drvload method, that the driver we were attempting to load was the correct version for the network adapater. On an earlier project, also with Optiplex 7040s, we found that the deployment kept getting stuck in a reboot loop once WinPE was loaded. That was not the first time we had an issue deploying Windows 7 to more advanced hardware. Most of Dell’s newer Desktops have these processors. However, the new processor also means that certain drivers and hotfixes have to be installed into the ISO for Windows 7 before it can be deployed.ĭell’s implementation of the Skylake Chipsets into its new desktops may be its first attempt to move on from Windows 7 for good. The Skylake processor is a follow-up to the Broadwell and provides increased CPU and GPU performance while reducing power consumption. It turned out to be much less straightforward than your typical deployment.Īfter encountering issues using our standard methods, we tried creating multiple bootable USBs, spent hours troubleshooting, and finally uncovered that the new Optiplex 7040s have Skylake chipsets. New hardware-which is better, faster, and stronger-is not able to support Windows 7 without customizations.įor instance, recently we (Danny Russell and Sulabh Upadhyaya) were tasked with downgrading a Dell Optiplex 7040 with preloaded Windows 10 to Windows 7, the operating system the firm still ran. We have discovered yet another reason to leave Windows 7 behind.
