    Windows could not complete the installation


    I am reformatting a Acer One 10 2-in-1 laptop with Windows 10 Home 32-bit, and after the first reboot (after copying files and such) Windows fails to continue the installation with this error
    Windows could not complete the installation. To install windows on this computer restart Windows

    And I can't proceed further.

    I am usign the official Microsoft tool to download and create a USB drive.

    Does anyone know what's up?

    Thanks

    Hi, for someone to assist could you advise:
    a. Did you completely reformat the disk before you started?
    b. Did you check the disk?
    c. Was the PC running Win 10 beforehand? If so which version (build/home/pro) and 32 bit or 64 bit?
    d. Which build of Windows are you installing now?

    And could you advise the processor in the PC as these came with an Intel Atom, I think.

    What was the reason for reinstalling- was Win 10 not running properly if that was what was installed?

    To check the disk now, you can use Kyhi's boot DVD / flash drive from the top of the Software and Apps section and e.g. run HDTune.

    Once confident in your disk, have a look at this:

    A yes I also redid all partitioning
    B yes and no errors

    C Windows 10 home 32 bit

    D the same


    I reinstalled it because it sometimes froze and see if fixes after reinstall
    I tried several USB drives several ISOs.I can read from your link that is something related to secure boot but in my case, unlike that user's UEFI is much more basic with those options and no CSM not Other OS not PK

    Windows could not complete the installation-img_0308.jpg

    And I tried every option specially the restore to factory but that error still pops I am starting to fear my computer is somewhat bricked or something.

    Thank you for your reply

    Please try:

    as I don't know how you checked your disk previously.

    Then reformat the disk- do not create any partitions, using the appropriate disk format for your PC.

    Then try reinstalling Win 10.

    Many thanks
    I scanned it using chkdsk and came OK.
    The computer has 32GB internal drive

    Doesn't have any S.M.A.R.T data

    It's using GPT (this machine is UEFI-only)

    I reformatted and repartitioned several times but always came the same error.

    I scanned using error scan and the entire window is red with 100% damaged blocks obviously it's not scanning correctly.

    Is there a log file or something to see where does it fail? Maybe that could clarify something

    panther commands


    When windows upgrade fails you can run the panther command to create an error code and log files. The log files can then be analyzed using the error code. I just had a failed windows 10 1607 to 1703 upgrade that failed with error code 0xc1900800. The log files displayed that it needed more free space in the partition. Files were removed from the partition. The 1607 was then upgraded to 1703. There were other problems after the upgrade though. A windows 10 1703 bootable iso was created. A clean install was then performed.

    This is the panther command:

    C:\$Windows.~BT\Sources\Panther

    It's easiest to use control c and control v and enter it into administrative command prompt.
    Then search for these log files:

    setupact.log
    setuperr.log

    What source are you trying to install Windows 10 from? Are you sure it is a good Windows 10 source? If it is a USB flash drive, you might want to try downloading a fresh ISO file and making a new one.

    Understood! I will post the latest lines of both files that may help!

    I got Windows 10 from the Microsoft download utility from another computer. Then I tried various USB drives, including an external hard disk, in all cases ended with the same error. The installation in all cases worked on a virtual machine used for testing

    You should not be doing any reformatting or repartitioning of the drive before installing Windows. You should let windows handle that.

    Boot from the Windows 10 installation USB flash drive or DVD. At the first install screen, press Shift+F10 to open a command prompt. In the command prompt run:

    diskpart
    select disk 0
    clean
    convert gpt
    exit
    exit

    The above commands initialize the drive for GPT partitioning, but they neither create partitions nor reformat partitions. Then when you get to the screen with the custom install option, select custom install. The next screen should show drive 0 with nothing but unallocated space. Hightlight the unallocated space and click Next to let Windows set it up.

    After trying your command and the same issue persisted *facepalm* I finally get it up and running by doing this:
    • On another computer, use a virtual machine on Virtualbox on UEFI Mode and install Windows 10, and cloning its HDD to a external hard drive using Macrium inside the VM.
    • Plug the keyboard base to the tablet to transform it into a laptop as the touchscreen doesn't work in bios nor in recovery mode and to have the USB port. Throughout the process, the screen will be SIDEWAYS as shown in the above image.
    • After that, plug the external HDD to the tablet and enter UEFI with esc key and boot from the USB
    • Windows 10 will boot successfully from the external HDD
    • Install all drivers from Acer
    • then using the same Macrium as used in the VM, I had to clone it to the tablet internal eMMC drive
    • Unplug the HDD and restart
    • Windows 10 will fail to boot and restart until it enters into recovery.
    • Reset it to a clean state and remove all files.
    • After that, the usual first-time setup will appear and the problem should be fixed.


    It's so easy, right?
    I still don't know why I can't install WIndows 10 normally like in the rest of my computers
