Dell Inspiron 5488/5558/5758 System BIOS Update Issue

I am writing to let folks know of two hidden Dialogue Boxes behind the install screen for Dell's BIOS Update. I tried to install  the Dell Inspiron 5458/5558/5758 HSW/BDW System BIOS update 2 days ago on my Dell Inspiron 5558 laptop. It is only a 5 Mb file, but after waiting for over 1/2 hour for it to download and install (with no error messages presented; only "installing..." visible), I minimized the installation screen. When I did, I found 2 Dialogue Boxes present: one acknowledging that one was going to change the BIOS, and the second one giving a "Yes" or "No"  to restart the computer. Once I did that, the installation finished without any problems. I just wanted to let everyone know that if your update is not showing any progress in a reasonable amount of time, minimize the Install screen and look for any hidden dialogue boxes behind it. Dell: you could improve this installation experience by coding those 2 pop up screens to appear in front of, rather than behind, the installation screen.
