Have tried 3 times. Message on update page says it did not install and I may try again. This is not a new install. Have been using for couple of years.

    I have tried countless times to install the 20H2 update to no avail.  I have even gone so far as to create a bootable USB drive with the 20H2 on it.  Got a message that I needed to start windows regularly and then click on the install.exe file on the USB drive. Got to 31% and then it froze.  Most of the other times I tried to do the update, it got to 61% before freezing.  Once it got to 91%.  I'm going to try one more time after uninstalling my antivirus software to see what happens.  Looks like I'm going to have to do a fresh install and then re-install all my software.  How depressing.  This is like a throwback to Windows XP.  You would think that Microsoft with all its brain power would be able to solve this problem with 20H2 that so many people are having.  I have tried to delete the $Windows.~BT folder that was created with the initial upgrade attempt but it requires special authorization other than administrative authorization to delete it.

    Sorry to hear that flashing BIOS didn’t help. 

    I’ve tried every step described in this thread + various YouTube videos and blog posts and nothing helped. 

    What did the trick for me is indeed flashing my BIOS and disconnecting all unnecessary usb dongles. The update has been then successfully installed, without issues.

    Same Issue. Dell Latitude E7420 from May 2021. Update constantly fails and it says will try again later. All latest BIOS updates are installed. COME ON Microsoft!!!!

    The BIOS update and driver update helped my computer not irreversibly crash (where I had to reload windows from scratch). I did another BIOS update today and windows 20H2 install attempt, but no luck for the ~10th time.

    Good Morning,  Thankyou for the advice on the Bios update.  I will check if Asus have a Bios update for the two netbooks ( same models ) that I'm trying to update. 

    Yes like you I have been talking about why MS have not realized that people want a simple OS without the Bloatwear. 

    I will keep this updated , especially if there is a Bios update.

    Thanks Again for taking the time to help.
