    reinstall from Recovery


    Having a strange problem. I want to reinstall windows from my HP Recovery Drive. (I know I can download the Win 10 Media creator Tool, but I don't want to). Since I have no longer have the Recovery manager (and HP doesn't make it available), I used 7Zip to extract the WIM file. It has all the files except the boot files, which I added (boot, EFI, bootmgr, etc). When I start up the laptop and boot into the usb drive, it says that my device isn't recognized. But it is recognized in another laptop. My other option was to reinstall from within Windows and click on setup. Then the error code is 'autorun not found or corrupt'. Any tips or ideas? Thank you in advance for your help.

    I used 7Zip to extract the WIM file
    This will not work, there's symbolic links etc... that 7ZIP won't handle. To extract .wim file to a partition, From Admin command, use:
    dism /Apply-Image /ImageFile:E:\install.wim /index:1 /ApplyDir:C:\
    *** Change the drive letter and file name E:\install.wim appropriately.


    I added (boot, EFI, bootmgr, etc)
    How did you create those ? and also it's wrong:
    boot & bootmgr are not needed, EFI System must be FAT32 format and set to correct ID. Correct partition layout for new Windows install should be: 500MB Recovery partition, 100MB EFI System partition, 16MB MSR Partition and C: Drive.

    In addition, you must set your BIOS to boot from UEFI Firmware

    An HP recovery drive may not work because the OS on your system is later than the one on the recovery drive and won't overwrite the newer one.

    If you make a Windows 10 recovery drive and if, your system was set up for Windows 10, it should restore your system to factory specs. A Windows 10 recovery drive process creates an image on the fly for the current Win 10 version.

    Don't quite follow what you mean. OP wants to wipe clean his C: drive then extract the factory image to it then set up to boot. Of course it will work

    @topgundcp, a Recovery drive will recover to a clean drive and reload OEM software. maybe, depending on how the system was originally set up. If the OP is trying to get back to a prior OS, then of course a Win 10 Recovery Drive will not do that.

    I think you use the Recover from Drive option after booting the USB drive to the repair section for such a situation. I have replaced all my OEM drives and used this method for doing so.

    Well, thanks, topgundcp and saltgrass. Unfortunately I am wrestling with another problem now: my hard disk is crashing. So I am desperateely trying to save my recovery drive by cloning it. That takes time. I did try to use the DISM command, and it seemed to work. Although as I was doing it with the Command prompt (admin), the system went along for up to 1%, then said 'file in use'. Now I am trying to decide whether to buy and new disk (hard or SSD), and even whether it's worth going through the trouble of opening up the laptop for that. But for now, thanks for all your tips and ideas so far.

    Dontunderstand why you want to install an old system which may be very old when you can just install 1803
