[SOLVED] Windows 11 beta build 22000.100 fails to install at 35% with error code 0x80070002

Hello,

I've been trying to install the new beta on my computer (currently on W10 insider build 21390.2025), but every time I try to start the update process, it fails after hanging on "installing 35%" for about a minute, simply giving the error code 0x80070002 as an explanation. I've tried the usual fixes for that problem:

  • Purging the C:\WINDOWS\SoftwareDistribution folder
  • Running sfc /scannow
  • Using the troubleshooter
  • Deleting catroot2
  • Looking through the Panther logs (I did find that the XPS and Print to PDF services were blocking the upgrade but after stopping them and repeating the aforementioned steps, the update still fails at 35% and the log files now don't point to anything in particular)
  • I even tried manually downloading and extracting the UUP files and running Setup.exe but it keeps failing on the "Making sure you're ready to install" step, simply saying "We can't tell if your PC is ready to continue installing Windows 11. Try restarting setup." without any googlable error code.

I don't know if this is related but I did have an internet connection issue during the first time I tried installing the update (router problems), which I initially thought was the reason for the failure. However, it's since come back, and since I've made sure to purge any cached files, I don't see how that could have been the cause.

If anyone has an idea of what could be the source of the issue, or if there's another way to update that involves neither the Settings app OTA, nor the Setup.exe method, I'd be very grateful.

Thank you in advance.

    Try 1 of these solutions:

    https://www.microsoft.com/en-gb/software-download/windows11

    I've already tried, the only one i did'nt tried yet was a fresh install with a installation media. I was trying to update preserving my files.

    If you already tried an in place update using the

    Media Creation Tool and it failed then the only other

    choice might be a clean install.

    Alright, I managed to get it to work. It seems the problem was that my SSD was still in MBR mode despite the motherboard being set to UEFI mode.

    To check if you have the same problem as I do:

    1. open the start menu and type "msinfo" then look at the "BIOS mode" section of the app that will open, like this:Image
    2. open a command prompt as administrator, type "diskpart", then when it's loaded type "list disk". Identify the disk that corresponds to your C: drive and see if it has an asterisk in the GPT column:
    3. if BIOS mode is set to UEFI AND the disk does NOT have an asterisk (mine does have one but that's because I took the screenshot after fixing it), then chance are you're having the same problem. What you need to do is to change your disk partition mode.
    4. In order to do that, you'll first need to backup everything important on your C: drive, cause you never know, and then I recommend you create a Windows 10 installation USB so you can fix things if something goes wrong
    5. Then, follow this guide to upgrade to GPT mode
    6. It is possible that Windows may have trouble booting up after doing that. If that's the case, don't panic, that's what the installation USB is for. Follow this guide and you should be able to fix it

    This is quite technical. If you have no idea what those words and commands mean, I'd recommend you wait for the official release, when Microsoft may have automated that process.

    Hopefully this is helpful to others!

    Hi,

    Thank you for writing to Microsoft Community Forums.

    In order to get clarity and to assist you accordingly, please reply with the answers to the questions below:

    • What is the make and model of the PC?
    • What is the make and generation of the processor?
    • Did you perform a PC health check earlier?
    • Does it meet all the specified system requirements?
    • Do you have any non-Microsoft Antivirus/security program installed?

    We would recommend you to download Windows 10 21H1 version installation media (ISO) using the media creation tool on the desktop of the PC and then refer this article by PaulSey to run an in-place upgrade. This Procedure will repair the corrupted or broken files on your PC, to make it a core edition and it will not remove your data or settings.

    Note: Please backup your important data that are saved in C drive to any other local drive or external drive before performing In-place upgrade.

    Regards,

    Aditya Roy
