Hi all,I have a Dell Precision 7520.This laptop is running Windows 10 Professional 21H2 and Dell Hardware diagnostic did not alert me about any trouble. I tried to execute BIOS upgrade without success today, in fact every time BIOS .exe package restart the system,but it never flashing the new BIOS release. Windows 10 started after a few seconds after Dell logo. In this moment my laptop is running BIOS 1.17.0 and I would upgrade it to the latest release  (1.26.0) I already tried the following steps today without success: I always runned software update "As Administrator".In my case BIOS has got Admin password and I disabled it, however the issue persist.What can I do? Thanks for your help! Federico
