    BSOD at bootup, error code 0xc000000f


    My daughter tried to start her laptop this morning to be confronted by a blue Recovery screen. It looks decidedly like a BSOD but I could not follow the posting instructions for this forum because the laptop won't boot. The message reads:
    ----------------------------------------------
    Your PC/Device needs to be repaired.
    The operating system couldn't be loaded because a critical system driver is missing or contains errors.

    File: \WINDOWS\system32\drivers\N360x64\1607000.04C\SymELAM.sys
    Error code: 0xc000000f

    You'll need to use recovery tools. If you don't have any installation media (like a disc or USB device), contact your PC administrator or PC/Device manufacturer

    Press Enter to try again
    Press F8 for Startup Settings
    Press Esc for UEFI Firmware Settings
    ----------------------------------------------
    Pressing Esc does nothing.
    Pressing F8 or Enter brings up the Startup Settings screen with options 1 through to 9 ranging from Enable debugging through to the various safe modes including with command prompt, etc. I have tried each of the 9 options and they all take me back to the Recovery screen.

    Now a bit about this laptop. It is an ACER Aspire R3 series, Model N15WS. It was purchased new in March this year. It did not come with any start-up or recovery software. It does not have a CD drive and only USB3.0 and USB2.0 ports for input.

    My daughter needs it for school every day and although this laptop is pretty slow and keeps wanting to update on her, it has been working properly until this morning. She has not installed any software within the last few months. The only changes to the system have been made by Windows with its incessant behind-the-scenes updating. It has Norton 360 Premier installed.

    It is a brick at the moment. If you could give me some direction to head I would be grateful.

    Can you boot it in safe mode?

    Thanks for your prompt response. No I cannot boot into safe mode. I cannot progress any options on the Startup Setting screen. With any of the options 1 to 9 it keeps returning to the Recovery screen.

    I fear I may have to download some recovery tools. I would then have to change the boot order in DOS to access the USB drive. Does this sound right?

    If you have a windows boot disk, you can boot into that. From there I would run scans such as SFC. SFC Command - Run in Windows 10 - Windows 10 Forums

    I created a bootable USB using rufus 2.10 and a Windows 10 ISO image I downloaded. The problem is I cannot get the laptop to boot to it. I don't have a CD drive, but two USB ports. I have tried both ports as well as mashing the F8 key and shift-F8 key combination. Whatever I do it still takes me to the blue recovery screen.

    As noted above, from the recovery screen pressing Esc does nothing.
    Pressing F8 or Enter brings up this Startup Settings screen:

    I have tried each of the 9 options and they all take me back to the Recovery screen above.

    Rather frustrating.

    Now that I have the bootable USB sorted, how do I boot to it?

    PS. Am I posting in the correct forum?

    Have you tried booting into the BIOS and selecting the USB as default boot? It could be F8, F2, F6, and you need to press the keys while it does the POST test. So before you see the windows logo you need to press the keys to be able to boot into the BIOS. Once you are in there you can chose the new boot option.

    Edit: Yes you are posting in the right forum.

    Thank you. It was F2 that did the trick. I changed the order pushing Windows Boot Manager and internal HDD down the list and placing the USB options as 1 and 2.

    First I tried USB HDD and then USB FDD. Both took a little longer but again brought up the recovery screen above. It got me thinking perhaps I am using the incorrect version of Windows 32Bit vs 64Bit. I have 64Bit on the USB drive but should this really matter if it is simply for booting? I've searched everywhere and I now know this laptop was issued in both 32 and 64bit. I'm not sure which one I have.

    Now I am in the BIOS I thought the information tab might tell me but it doesn't, well not obviously so. Is there any way of finding this out?

    Also, there are other settings under the Boot tab like UEFI, which is enabled. Not sure what this is but thought I would mention it.

    Did you try USB CDROM?
