Windows 10: Unable perform clean installation, Windows 10, Error message: Drive Locked.

I want to do a "clean install" of W10 from disk on my new T5820.



1. I tried to do so after setting the firmware to "Legacy" and selecting SATA AHCI. The install seemed to be going normally until I got to the "100%" indication and got a message about "TPM". It said something like this, "...You've changed from the preferred install. (AHCI instead of UEFI, I presume). If you want to keep those changes, hit "esc". If you want to revert those changes, hit F12". (Queries could be reversed, I don't remember.) I did one of them first, and the installation program began again on its own. When it got to the same TPM message again, I did the other. The machine once again began the installation program all over again on its own and then stopped with the same TPM question. Attempted the install 2 times each way. IOW... regardless of which option I chose, it would not continue the install.



2. I tried again from "UEFI with legacy ROM enabled". But first....

I tried to run a Low Level Format on a drive from W10 and got an error message, "Unable to continue. Unable to lock the drive." So.. I ran the LLF utility from my W7 machine and it appeared to function normally.



After the LLF, I tried to again do a clean install of W10 from the disk. I got an error message, "Drive on which Windows is installed is locked. Unlock and try again". (Nothing nor Windows was installed on that drive.)



So... LLF on one utility says "unable to lock the drive". On the other, it says, "drive locked". Which is it? Can't be both at the same time...



3. I tried doing a clean install by overwriting a functioning drive with W10 on it. Once again, I got the message, "drive locked".



4. I tried again with a new drive... one which had never been partitioned or formatted. Same message... "drive locked".



I searched online and found this problem. Most of suggested solutions said to get into the "UEFI settings", I guess to verify or change some setting... but I am unable to do that. I don't have that as a choice. I only have the choice of "UEFI" or "Legacy". I can "reset UEFI settings to be as the manufactured shipped"... but nothing else. I cannot see the actual settings.



So, here's where I am...



1. Does Dell have a fix to correct this "drive locked" issue?



2. Is there some UEFI setting I've got wrong? If so, what are the proper settings and how do I get into the UEFI settings page to correct?



3. Or... has Dell made it impossible to install W10 from a disk?? Am I forced to install W10 "Dell's way"... from flash drive only... after downloading from Dell's website?
