    Stuck at windows Hello!


    Hello, I'm new here, so I apologize in advance if this thread is misplaced.

    I just had a weird problem, but before I continue, I'd like to mention what happened before it occured to give you some context:

    My system has two partitions: the System one (C), and a recovery one created automatically when I installed windows 10.

    I made the recovery partition hidden.
    And I created a new partition from the free space in C using "Aomei partition assistant pro"
    Since the process included using the System partition, it required rebooting the PC (for the software to work in "preOS mode"), so I did that, and after the operation finished, I was in my login screen, everything was fine up until this point, but then I realized I couldn't login.

    when I'm in the lockscreen I can press any key, and the display sort of slide up to reveal what's supposed to be the login screen, except there is no input box for Me to enter my password!
    I can use my mouse and keyboard to select anything on the screen (change language, bring up on-screen keyboard, shutdown/reboot..etc) but I just can't enter my password.

    Panicked, I started regretting doing what I just did to my disk, so (after a lot of trouble) I managed to wipe the newly-created partition, merge it back with C and unhide the recovery one, and then rebooted, but nothing!

    Now I have no clue how to solve this problem since that's literally the only thing that I can think of that could potentially cause a problem to the system.

    Note: there is one other thing: this last week I've had a few BSODs with the "driver power state failure" error code but I'm not sure if that's related.

    Any help would be appreciated...

    Thanks in advance

    Have you tried any of the steps in this thread?

    No login prompt at login screen

    Your build of 10 seems original from, from system specs, like even before the 1511 or Anniversary update. Are you preventing the updates?

    When you install Windows, it should create a Hidden 100-500MB System Reserved Partition with no drive letter that has the boot information in it, as well as a Hidden 500MB Recovery Partition also with no drive letter. These partitions should not be tampered with.
    If you want to a new partition, then in Windows, go to Disk Management and Right click the C: drive and Shrink Volume. Leaving enough Unallocated Space to create the partition you want, then Right click the Unallocated Space and choose to create a New Simple Volume.
    As for where you are at now, Do you have Windows 10 install media?
    If you just installed Windows, then I would start over, and this time, choose to make a Secondary partition in the Drive Options under Custom Install.
    If you want to try to salvage the install, Boot off of the Windows install media, choose your language and then choose Repair Your Computer.
    Or press Shift+F10 to go directly to the Command Prompt, at the X:\Sources prompt, type C: and press enter. Type DIR, see if there is a Windows directory (it may not be the OS drive) If not, type D: etc. At the OS drive type
    bcdedit /fixboot, try to boot normally, if that fails, type
    bcdedit /fixmbr try to boot normally, if that fails type
    bcdedit /rebuildbcd

    @sprunk thank you for your reply, but it didn't work for me,
    By bcdedit I'm assuming you mean sfc? Either way it didn't change anything (I did try fixmbr before posting)
    Bcdedit itself is not useable (the boot configuration data store could not be opened.the requested system device cannot be found)
    Some more info: I'm on windows 10 anniversary update with the latest updates installed.I don't have a windows installation media ready but I do have a recovery drive created on my desktop, and that's what I used to enter the troubleshooting screen.
    The pc that I created the drive on has a different build of windows 10 and has UEFI as a bios mode unlike the laptop in which I have the problem, does that matter?

    I do not mean SFC /scannow. BCEdit commands are not available in the Windows Command Prompt, you must boot off of the Windows Install media and get to the Command Prompt in the RE (Recovery Environment) from there.

    Sorry I meant bootrec not sfc!
    now I'm booting from the install media and bcdedit is recognized (on all drives) but the arguments fixboot, fixmbr and rebuildbcd are not correct
    (That's why I asked whether or not you're talking about bootrec)

    Yes, go ahead with bootrec and with an additional of bootsect.

    @spunk @Private Thank you for your replies.

    Bootrec and bootsect ultimately didn't do anything so I eliminated the possibility of it being a boot problem (it WAS technically booting anyway)
    So I added the safeboot entry to bcdedit, logged in into my account, rebooted (in normal mode), and BAM! There it was, my password prompt in all its glory!

    I'm guessing the system component responsible for the prompt was having an issue and when I entered safe mode, it was reset.

    Thank you again for your assist.
    But for discussion's sake I want to share a few more details:

    When I said I had 2 partitions, that was excluding the reserved one (350Mb) which was always hidden and inaccessible.
    The recovery partition that I hid initially was deliberately left unhidden by the installer, and that's why I thought it was safe to hide it in the first place.

    But now I noticed that there is no longer a "reserved partition" and the recovery partition is now hidden by the system...

    Not that I complain, I have everything working better than I was hoping but, it's still curious, Any thoughts on this?

    that is the way it should look by default.
