    Unable to reinstall Windows 8!


    Hi,
    I recently installed Windows 10 technical Preview on my Samsung SmartPC XE500.
    Today i wanted to set it back to factory mode, but it only reinstalled Windows 10. =/

    So I put in my recovery USB flash drive. Booted with Volume up + Power, and it finally booted the flash drive.
    No i wanted to reinstall everything, but it does not work.

    All i got is 'Unable to rest your pc. A required drive partition is missing'. I guess this is because Windows 10 deleted the original recovery partition.

    BTW the recovery medium i've made does not contain the $PBR_Diskpart files. Maybe this is the problem?

    Is there a way to fix this? I really need to reinstall Windows 8.

    The right partition structure is here somewhere. I get lost in all the threads. Will search the forum or internet.

    EDIT: I hope this helps: Configure UEFI/GPT-Based Hard Drive Partitions

    Try this method: Need help reinstalling Windonws 8 from USB

    Copy CreatePartitions.txt and ApplyImage.bat into the root directory of your recovery USB flash drive. Then run the Diskpart script and ApplyImage.bat batch file.

    Please take note of this:

    The recovery image partition size is 20480 MB (20 GB). NOTE: You can decrease the recovery image partition size.

    Thank you @genet.

    Unfortunately the 'ApplyImage.bat' didn't work the way it supposed to. It only copied the install.swm files over to the right partition.

    I now applying the image via dism manually and then also try to copy winre.wim. I hope it'll work.

    md T:\Recovery\WindowsRE
    xcopy /h W:\Windows\System32\Recovery\Winre.wim T:\Recovery\WindowsRE\
    Click image for larger version

    For some reason, the command does not work with all OEM computers.

    W:\windows\system32\recovery\winre.wim does not exist.

    Does anyone know of a solution to the problem?

    I got the same message. But that's not the problem. W:\windows is the new main partition and this is the path where the install.wim image is applied to.

    The problem i got was, that the tool copied the install.swm into the right folder, but didn't even try to apply the image to W:\. That's why the tool goes straight to coping Winre, but it's not there yet.

    dism /Apply-Image /ImageFile:R:\RecoveryImage\install.swm /SWMFile:R:\RecoveryImage\install*.swm /Index:1 /ApplyDir:W:\

    this is what i did manually. After that i loaded the ApplyImage.bat again and after that it copied and registered the WinRE.wim.

    I can now boot correctly in windows again, with the recovery image from samsung. The only problem i've got left is, i can't set it back to factory settings via the control panel. I always get an error.
