[SOLVED] Build 18890 Fails to install. 20H1
solution:
I've been using this method for the past few fast ring insider builds and it never fails. the procedure is to make an ISO file for each build but of course it's all done automatically and downloaded Officially from Microsoft servers, this is just an automation script.
use this website: https://uupdump.ml/known.php
select your build number
select language and click next
select the right edition and click next
then click on "download using aria2 and convert"
after that extract files to a folder and run the "aria2_download_windows.cmd" file.
wait for it to finish, once it's done it will create a complete and official ISO files which you can use to install your next Windows insider build without any problems.
HotCakeX Mine fails too but it does not show any errors. It downloads the update 18890.1000 (rs_prerelease) and when done it 'prepares' the update for installation, goes on to install counting up to 100%, it restarts and shows a blue screen where the update seems to be installing in full also then it restarts and shows the logon screen. When I log in it still sits in build 18362.1, and it re-downloads the entire update again (also tried deleting the SoftwareDistribution folder contents etc), prompts to restart and installs again and again as above... but nothing changes after that, build remains unchanged. This went on till my data bundle was all consumed... I hope Microsoft fixes this.
Why are you jumping from 18362 straight to the 18890?
between all those builds that you're skipping, Microsoft released some fixes, one of them was needed to come from 19H1 to 20H1, so chances are you are getting that different error due to something else.
but it could be also from the 18890 itself. i just hope Insider team actually confirm that this problem exists and don't go on and ignore it. because that's what they have been doing so far on Twitter.
HotCakeXIt all began with a crash in Windows that rendered it almost unsable, It had the famous spinning circle of death (had a power failure at my home while PC was running). I had to restore it's core using DISM … (restorehealth). All other repair attempts would not work, except for DISM that worked to fix the underlying core functionality and cleared most of the issues while introducing an update nightmare. When it came up I could tell it was broken from the "Some setting are managed by your organisation..." message in the Win Update and Insider settings were now disabled too. So I tried to fiddle with gpedit and the registry concerning what is published about controlling updates and Insider options... nothing really worked well. I had to go to these lengths because I had to either do a fresh install and reinstall close to 200+ applications and games, or choose the lesser evil and have it work with its dents and scratches. While trying to fix the SCOD I tried to update to the same version using 'media creation tool' but that would come up with 'Keep apps and personal files' albeit grayed out, only fresh install was available... In general after SCOD, the only fix is to fresh install, or live with a crippled OS that wont even update to patch the problems but at least get to keep your apps and files.
that's really unfortunate. I have few suggestions for you since i've experienced all that too but you might already know these too
consider using a SSD for your OS drive, that way even in case of power failures and such, you won't lose data or get corrupt files in OS.
another, you better install games on other drives than the one OS is installed on. if you're using Steam then it's Super easy to move game files. if you're using Uplay client it's also easy since they both have built in options. if your games are from Windows Store, you can choose a different drive before starting to download the game.
doing these will hopefully lessen your problems ༼ つ ◕_◕ ༽つ
HotCakeX I agree, but I'm a nerd and I work hard and need quite a large drive C:\ at least 1TB, but ideally 2TB... so you see my pockets would need a needle and thread after paying for such a large SSD... am already saving every penny to do this, after spending quite a lot to get my server upgraded from 8GB RAM to 32GB RAM just recently. FYI, I will pretend I don't also need a GTX 1080 and 27" LED HD second monitor as well... At least I've managed to get a mechanical keyboard and high DPI mouse, I just need to figure out which bank to bust and how fast to run from the cops to afford that 'Hah...' refreshing moment when I sit at my desk to work... LOL
