Windows 11 Insider Preview 10.0.26200.5516 (ge_release_upr) installing Failure

 



After searching, I found that we should have around 30 GB of free storage, 
but after deleting things and leaving what's necessary, I still cannot install it.
The installation stops at 35% and displays the above.

Please help me out !!

    Try these all the standard fixes (freeing up space, troubleshooting updates, using the ISO, disabling antivirus, resetting Windows Update components), and it's still failing at 35%, here's what we can try next:

    1)

    Do a Clean Installation of the Insider Build (Recommended)
    At this point, the most stable way forward is to do a clean install of the latest Insider Preview.

    This wipes your current system, so back up important files first.

    2) 

    Use Media Creation Tool + Offline Upgrade (Hybrid Method)
    -> Use UUP Dump to create a custom ISO for build 26200.5516

    This often succeeds where the regular update or insider ISO fails.

     

    Hope this would fix your issue :)

    Regards,

    Try Windows Key +X > Terminal (Admin) 

    Powercfg -h 

     

    This disables hibernation and should free up good amount of space. 

     

    Otherwise in the same Terminal session use winget to search and install treesizeview.free

    Often it's Apple phone Backups eating up disk space. 

    Using OneDrive? You can setup folders with large rarely used files to be on demand only. Check your OneDrive sync settings and file Explorer settings. 

    Please mark as solution if this helped, otherwise reply and tag me.

    Usually the 120 GB can serve well enough.

      Thanks for suggestion.  Normally I would consider larger drive install.  Considering the 'overhead' that  Ai must take today it would seem to make some sense to have more space.  That said, I don't understand why Windows seems not to take advantage of my 64gb memory and two GTX980 boards to speed some things up.  Updates, etc. are slow.  Back in the 'good ol' days' a large ram drive made things seem instantaneous....  .   I know, buy a new machine...

        That is not much todo with AI. Windows 11 is most modular. 

         

        If you need a very compact version then consider GitHub Tiny11.ps1.

        You can also upgrade your rig with a larger SSD, they are not expensive. 

        NVMe (via sabrent PCI-E to NVMe Adapter) would be an option but since you have two 980, the PCI-E slots are blocked. Is there a specific reason why using the Insider version? It has more experimental features and eventually debug code.
