    Unable to Factory Restore - Win 8.1-Asus N550jv (oem)


    I want to set my system back to factory restore. with every try of Refreshing or Recovery, system is giving error of locked or missing partition. i have searched for this issue and found that its all about microsoft blunder(upgrading win 8.1 from windows app store).
    all of my recovery partitions are there in healthy state. i have made factory image backup by using Asus BackTraker.
    but still i am confused will it work fine with all steps or not, as i dont want want to be stuck in between the procedure resulting in sending laptop to company with expired warranty.
    please help me in describing step by step. also let me know what i have to do before running factory image backup from usb(other than saving win 8 product id).Click image for larger version

    Go to this ASUS support page. It has everything you need to know in the FAQ. The asus recovery software is usually really good(I have a X54C with windows 7 HP) if one makes his recovery media after first time installation. I have many system images plus a clean install copy of win 7 and my 5 DVD I made using another program like backtracker that put the recovery partition on DVDs and the worked perfect, just that the crapware(30 day Trend Micro trial) will be reinstalled too.

    Thanks Cliff. i have done this step yesterday. but i am bit scared of crashing system with any unexpected error (as on different forums people mentioning about win 8 cd and errors or sticking windows in between the process). thats y i posted this thread to re confirm if these steps will go smoothly or should i need to perform some extra steps before messing up the things.

    As long as you made the backtrack recovery image before you switched your partitions around (to me it looks like you switch your OEM recovery partition 350MB around with your C: partition). But as always before you do any major changes, back-up your data.

    i have not touched partitions. this is the first time with this system i am gonna restore. i just upgraded win 8 to 8.1 from app store. in your personal opinion, what you think.... should i proceed to with usb restore? else the only option is to take laptop out of city to company with a handsome amount of money.

    Personally I would try it, but maybe if you can wait see if someone else in the forum that has used Backtrack comes to word. I thought may you had moved the partitions around because that 350MB recovery is definitely in the wrong place between C: and D.

    IF I MAY -

    Right click start flag - command prompt (admin)
    type diskpart
    type list volume

    you will see volumes without drive letters assigned to them (thus the # sign below)

    type select volume #
    type assign letter=@

    (@ being a drive letter that has not been assigned already G H I J K etc.)

    the 20GB partition has your factory recovery image "install.wim or Install*.swm(s)

    tell us the drive letter you assigned that 20GB recovery partition and the folder you found the install.* is in

    Windows 8.1 update did that, it kept his existing partitions and created its own 5th recovery tools partition that it needed without overwriting the existing windows 8 winre tools partition..

    we now need to tell windows 8.1 to use the windows 8 winre tools and factory recovery image

    Uh huh...good thing most new pc's come with 1TB drives or lager. If that happened on an old 350GB drive, I'd be ripped. Reading stuff like this reminds me why I started making the recovery media that windows and/or computer manufacturer "recommend in desktop pop-ups right after installation, and system images after completed set-up(stored on disconnected small usb HDD in closet with date & os tagged on, and monthly systems images(screw back-ups I want the whole 9 yards) and now with windows 8.1 update daily file history to second internal drive. Of course in the Artillery using the Battery Computer System the could crash because of sudden power loss any time it was drilled in BACK-UP BACK-UP BACK-UP! We even had to back-up the alternate computing system(BUCS).
