    ASUS Laptop to factory, "some files are missing" thing


    Hello all!

    So, before creating a thread, I searched everywhere and found people with almost the same problem as me, but not equal. So I thought it would be better to request specific assistance before messing something up.

    Here's what's happening:

    I have this asus laptop for like 7 months, he came with w 8.1 oem, during that time I did 4 or maybe 5 full restores (back to factory settings) and it all went smooth. But today, I tried to do it again (system is slow) but I've got a big surprise:

    "Some files are missing. The installation or recovery cd from your windows copy will supply this files", a free translation since my OS is not in english.

    I don't have this recovery media thing and as said, I already succed in the past restoring this PC. So I have no idea of what is happening...

    I follow these instructions
    :
    - Open CMD
    - Type diskpart
    - Type list disk
    - Select the disk with the recovery partition, using select disk # (mine was select disk 0)
    - Type list partition

    I found that everything is maybe as it should be, I have 2 recovery partitions out of 6 partitions in total (1 sized 900mb and anoither 20gb)



    What should I do?

    command prompt(admin)
    Type> diskpart

    type> select disk 0
    type> list partition
    type> list volume
    (post a pic)

    you will see a lot of volumes without drive letters assigned..
    Now find the 10-20GB volume #
    type> select volume # (# being the volume number without a drive letter)

    type> assign letter=r
    you can now Browse thru R and find Install.wim or Install.swm(s) - those are your Factory recovery Images..

    type> exit (to exit diskpart)
    type> reagentc /disable

    now, assuming the install* file(s) are on "R" and in a folder called "RecoveryImage"
    Note: Change "drive letter" and "folder name" below to suit your system setup

    type> Reagentc /Setosimage /Path R:\RecoveryImage /Target C:\Windows /Index 1


    type> reagentc /enable
    reboot PC

    Thanks a lot for your help KYHI, I'll give it a try later. I was also thinking about doing a clean windows 8.1 install (to get rid of those crap programs that usually come on an OEM installation).

    Using this tutorial: Need help formatted genuine windows 8 in lenovo

    Do you think it should work or it is possible that this might mess something?

    following the guide you linked - it will remove the factory recovery and the factory bloatware..

    Thus you'll be doing a CLEAN install.. Many Prefer a clean install over factory bloatware..

    if you follow my steps - you can then create a factory recovery drive ( control panel > recovery > create a recovery drive )
    save the usb for later use if you ever wish to return to factory settings,,,

    once you have the factory recovery on usb - follow the guide and clean install windows 8.1

    The 'ASUS Backtracker' programm does the same thing (Back up the factory recovery image option) or it is more reliable to do the way you said?

    I am thinking that since he already had 8.1 OEM installed and that reset worked several times before..

    The factory recovery image is missing or he created another partition..

    Usually 8 to 8.1 upgrade knocks out the recovery option by adding a second recovery tools partition - Asus backtracker fixes that..

    Thus the needed suggestion for posting a pic of diskpart and searching for install.**m

    I used the backtracker but on the usb flash there is no such thing as setup.exe, is something messed up?

    As far as I can tell it is all normal (the folders), expect for the setup.exe that is not in there.

    To correct the missing Registry sources try the following.

    Open Action Centre, Recovery, System Restore, tick Show More Restore Points and look for the following Auto System Restore. highlighted on the System Restore attachment.

    After you have re signed in you must restart the computer for the update to take place.
