    Recreate ASUS F9 recovery functional partition


    As many did, I upgraded my ASUS G751JY from Windows 8.x to Windows 10, and this destroyed ASUS F9 built-in recovery feature. When I press F9 now it will give me a BSOD with:

    Your PC needs to be repaired
    A required device isn't connected or can't be accessed.
    Error code: 0xc0000225
    [ A text saying I should use recovery tools on my installation media to fix the issue. ]
    Press Enter to try again
    Press F8 for Start-up Settings
    Press Esc for UEFI Firmware Settings


    This happens every time I want to use F9, then every time I have also to repair Windows boot (have no problem, I know how to do this and regenerate a correct BCD), so my idea now is to recreate a generic Windows 10 install partition working with ASUS F9 feature.

    Here is my current situation:

    but Recovery partition was Disabled.
    No problem. I've managed to re-Enable it using the REAgentC command:

    Code: C:\Users\Luca\Desktop>reagentc /info Informazioni di configurazione per Ambiente ripristino Windows e la reimpostazione del sistema: Stato Ambiente ripristino Windows: Enabled Percorso Ambiente ripristino Windows: \\?\GLOBALROOT\device\harddisk0\partition4\Recovery\WindowsRE Identificatore dati di configurazione di avvio (BCD): fc0612d5-20ce-11e6-8adf-9bc77791b978 Percorso immagine di ripristino: Indice immagine di ripristino: 0 Percorso immagine personalizzata: Indice immagine personalizzata: 0 REAGENTC.EXE: operazione riuscita.[/quote] ASUS F9 still not working giving me BSOD Erorr 225.

    Following some guides on the net I've been also able to create a generic "install.wim" starting from MediaCreationTool's Windows 10 ISO file and "<mounted Windows 10 iso>:\sources\install.esd", using the DISM command:
    dism /Export-Image /SourceImageFile:"MY_ESD_FILE" /SourceIndex:1 /DestinationImageFile:install.wim /compress:recovery /CheckIntegrity

    How do I proceed now?
    • Add a new additional 4GB recovery partition with GUID ID: DE94BBA4-06D1-4D40-A16A-BFD50179D6AC
    • copy "install.wim" into this partition (requires a specific dir structure or the root will be enough?)
    • use "REAgentC /setosimage ..." and target to the new partition with the wim file

    Is this correct? Will this make ASUS F9 work again? *sarc

    :)

  2. "Something went wrong" while trying to create account during installation

    Try resetting the laptop to factory state then try again.

    New computers that come preinstalled with Windows often have what is called a recovery partition. This is used to reinstall the operating system in the event of a system crash. To access it, you will need to boot into when you start your computer by pressing
    a function key. This can be either F1, F2, F9, F10, F11, F12 or even DEL or Tab key. Consult the owners manual that came with your PC for instructions about how to reinstall Windows.

    This is how the recovery partition is accessed for the most popular makes..

    For Asus, press F9 as soon as you see the Asus logo.

    Power down the laptop by holding down the power button.

    Start it then boot into the recovery environment, then follow the instructions to perform a factory reset.

    correct - as far as the OS Image Recovery
    Not sure about F9

    as you would have to regenerate the bootkey
     
  5. hexaae Win User
    So I don't need a specific directory structure for the install.wim file?
    Can I put this in the new additional 4GB recovery partition and just use the usual:
    Reagentc /setosimage /path <driveletter>:\<folder-containing-osimage> /index 1 /target C:\Windows ?

    You can use the E: drive
    copy the install.wim into a RecoveryImage folder
    then point to it...

    or you can shrink E: and create a RecoveryImage partition...

    the install wim has to be in a folder - not on the root of the partition...

    ONE MAJOR NOTE...
    If you reset the PC your Data partition E: will be removed... So very important that if you reset - you MUST select keep current partitions...

    that is the problem with having your DATA on the same Drive as the windows OS
     
  7. hexaae Win User
    Yes, my idea was to keep the current 470MB Recovery partition and add the install.wim I created from Windows 10 ISO ESD file into a new partition after E: (I'll label this R: ). Something like R:\Recovery_Win10\install.wim

    Thank you for the "keep current partitions" hint

    You are way better off - not using the Recovery Option at all > with your current disk/partition layout....

    If windows ever went bad - just run the windows 10 setup.exe - from within the current windows 10 OS
    To repair windows and keep your files and programs..

    ...but unfortunately ASUS F9 still doesn't work as expected (here is a working video from YT) and returns the usual BSOD Error 225 mentioned in first msg *Sad
    Mmmh... I start to think F9 simply works by booting from the first Recovery partition it can find, usually put after C: on ASUS G751JY laptops as shown in this example pic coming from an online review:

    Recreate ASUS F9 recovery functional partition [​IMG]


    Probably it expects to find something more than the install.wim file there as it asks for winload.efi pressing F8 after BSOD is displayed:

    EDIT: maybe I could try copying the entire Windows 10 ISO inside the first recovery partition and see what happens pressing F9...

    The factory recovery partition more than likely contained an executable file that F9 ran which would then control the restoration. That's why most people when they talk about leaving the factory recovery in place after an upgrade to Windows 10 are likely to be disappointed to discover they can't really use the recovery partition left behind because, more than likely, manufacturer software is going to be required to actually do a recovery from it.

    I think the only way you will get F9 functionality back would be to restore the original factory recovery partition.

    Let's see if I can find another G751JY user with working F9 so we can discover what's inside the 12GB recovery partition from ASUS...
    Honestly I can't remember if I manually deleted the original partition or was wiped out by Windows 8.1 -> 10 upgrade (more likely).

  12. I Recently got a Asus Desktop with F9 recovery, unforuately was too in a hurry to get it setup with 10, to make backup copy of original config lol, my fault I know, soon doing clean install of 10, so think gonna wipe out the partition then, I got a copy of 8.1 Core on another flash drive, Original system key in uefi saved, plus Windows 10 USB drive, and system repair Disk made as well. So think i'll be ok if something ever goes wrong.

    Recreate ASUS F9 recovery functional partition

    Well, it's never a problem to repair Windows boot or wipe out everything and reinstall a clean image...
    For example I use Macrium Boot Disc that has a handy "Fix Windows boot problems" and quickly fixes BCD to re-enable Windows 10 boot... or you can use an official ISO downloaded with MediaCreationTool if you need...
    The problem though is loosing F9 functionality, which was useful after all, but Windows 10 upgrade didn't like that, I'm afraid *Wink
