After working with Dell Support offline, the solution to this problem was to reset the BIOS to Factory Defaults.
Hello I'm trying to clean install windows 10 in an Inspiron 3593. I have downloaded the latest Dell Windows 10 ISO (USB option) using the Dell OS Recovery Tool and tried a clean install following the instructions shown in the How to install Windows 10 from the Dell ISO  (e.g. exactly as the video in this page). When installation reaches @ Getting devices ready (and @ random completion % each time), the whole procedure freezes, that is, the dotted circle freezes and does not proceed further even when the laptop is left in this state for several hours. See below photo as well...  Any ideas are welcomed. [IMAGE]   Since everything is deleted from the HD (??), when I tried to download the SupportAssist OS Recovery option in the USB, it does not work and it also freezes when SupportAssist starts (after selecting with F12 the USB). The procedure I follow is  Thank you
