In another forum someone speculated whether that might do a clean install. Then they tried it, said it did not, it did the same thing as the manufacturer recovery media, brought the computer back to the state it came from the factory, bloatware and all. It occurs to me though--what if one deleted the manufacturer recovery partition, and then did this Reset Windows thing. The system would not have the manufacturer recovery, so could not set it back to factory. Might it then do a clean install? Anyone tried that?
    You would still need the Install.wim or the DVD.

    For reset windows?

    It looks like a standard recovery option, that one can access from the built-in Windows recovery partition (which looks like two partitions on my computer), or the recovery boot media one can create from Win8.

    As said, some have reported doing that and getting a factory reset, which is not a clean install. Therefore, I was wondering if one deletes the manufacturer's recovery partition (in my case a 10GB one from Lenovo), while keeping the two much smaller Windows recovery partitions, then does that reset, it could not reset to factory without the manufacturer partition, so I wondered if then it would do a clean install?

    It is possible that install.wim is on one of the Windows recovery partitions. Then it should be there, on any Win8 computer. (As said though, I did the recoverydrive command to create a recovery USB flash drive, and did not see any file named install.wim on that.)

    I will guess that one is only asked for an installation disc when one does reset, if one has deleted the Windows recovery partition (again, in my case it seems to be on two partitions).

    Install.WIM and now?


    Hi,

    I got the install.wim from the hidden recovery partition using Paragon Software (free Edition --> advanced mode --> extract from hidden partition to local hdd --> so no need to use the discpart tool).

    But now I don't know, how to create a bootable DVD or USB just from this one file.
    All the tutorials I found here Forum need an ISO-file that I don't have.

    Does the oscdimg.exe create also an ISO just from the install.wim ?? (not tried as the parameter tells something from boot files)

    I need the bootable device as I want a fresh install from my preinstalled Win8 OEM to a new SSD Drive. (and ASUS doesn't provide any install medias *grrr )

    regards

    information   Information

    We always assume you have made your Recovery Disks using the OEM manufacturer's Recovery Media Creator app the first day you had your new PC.

    You can use the ASUS version of

    or you can clone the HDD to the SSD.

    You can use dism.exe to apply a .wim image to a formatted volume (partition or disk or mounted virtual hard disk) which has been assigned a drive letter and made the active partition.


    It is possible to apply the Windows install.wim image using dism.exe - which is found in your c:\Windows\system32 folder.


    The command (elevated command prompt) is


    dism /apply-image /imagefile:d:\sources\install.wim /index:1 /applydir:t:\


    (this is absolutely equivalent to: imagex /apply d:\sources\install.wim 1 t: but without the large download needed for imagex.exe), where d:\sources is the path to the install.wim file and t: is the target volume drive letter.


    Both methods take a similar time to apply the image. ~20 min

    Then the boot files can be installed using bcdboot

    bcdboot t:\windows /s t: /f ALL

    On first bootup you should be taken to the OOBE to setup location, user network and activation.

    I already read that topic but I'm afraid of the different alignment of the SSD after cloning it.... so there is a link to a check-tool... but what if the alignment is not correct... could this get fixed after cloning withour reformating the SSD?

    It's my first SSD ... so sorry for those "newbie" questions.

    Unknown with that free tool, as I use Paragon alignment tool, which paid for software.

    A general question: There are many reasons why one might want to do a clean install on a system that came pre-installed from the OEM. However, if the *sole* purpose of doing a reinstall is to get rid of bloatware, then I do not understand why users don't simply uninstall the bloatware, this can be done in 3-15 minutes depending on manufacturer. Isn't this the fastest and best way?
