    Inaccessible boot device after updating from April 2018 to May 2019 update


    Currently running a dual-boot system on a Lenovo Yoga 730 with manjaro and windows 10.

    Upon restarting and allowing Windows Update to upgrade to the May 2019 update, I get a stop error with INACCESSIBLE_BOOT_DEVICE.


    Initially, GRUB menu wouldn't appear, but has now appears but will not boot linux.


    How do I go about fixing this?

    :)

    Windows 10 April 2018 Update(SCU) Partially Breaks MKV File Support?

    I updated to main computer to the April 2018 Update, AKA Spring Creators Update, and it seems like they've taken a step backward with MKV file support. When I go into the properties of an MKV file on the Fall Creators Update, if I go to the details tab it gives me a bunch of detail about he media file, like resolution, framerate, audio information and bitrate. However, if I go into the same file's properties on the April 2018 Update, almost all of the information is blank, it only gives me a runtime and bitrate.

    I really just want to confirm that this isn't just my computer and other's are experiencing the same thing.

    INACCESSIBLE BOOT DEVICE after Win10 Update


    1) Find a flash drive that you can format ( > or = 8 GB)
    2) Create a bootable windows 10 iso:
    Download Windows 10
    4) Insert the flash drive into any USB port
    5) Open the BIOS and temporarily change boot order so that you can boot using the flash drive.
    6) When the iso loads choose language, time, currency, and keyboard, or click next
    7) In the left lower corner click "repair your computer"
    8) Click troubleshoot
    9) Click command prompt
    This should open: Administrator: X:\Windows\system32\cmd.exe > X:\Sources>

    For all of the steps please use a camera or smart phone camera to take pictures and post images into the thread.

    10) type: bcdedit | find "osdevice"
    11) This may display osdevice partition=C:
    12) type: diskpart
    13) type: list disk
    14) type: list volume
    15) look under the column heading Fs for any volume that displayed RAW instead of NTFS
    16) type: chkdsk /f /r G: (change G to the drive letter of the volume displaying RAW)
    It may display "The first NTFS boot sector is unreadable or corrupt."
    This may then convert the RAW volume to NTFS.
    17) Type: exit
    18) reboot to open the Windows advanced troubleshooting menu > command prompt > Administrator: X:\windows\system32\cmd.exe > X:\Sources>
    19) type: bootrec /rebuildbcd
    It may display:
    Scanning all disks for Windows installations.
    Please wait, since this may take a while...
    Successfully scanned Windows installations.
    Total identified Windows installations: 1
    [1] D:\Windows
    Add installation to boot list? Yes(Y)/No(N)/ALL(A):
    20) Type: Y
    The operation completed successfully.
    X:\Windows>
    21) Type: exit
    22) reboot
    See if the inaccessible boot device problem was fixed.

    If the above did not fix the inaccessible boot device the next step is to remove the recent update:
    23) Open command prompt > Administrator: X:\Windows\system32\cmd.exe > X:\Sources>
    24) From the first command displaying the partition if the drive letter is different than C: please use the displayed drive letter for the next step
    25) type: DISM /image:G:\ /cleanup-image /revertpendingactions (change G to the applicable drive letter)
    26) This should remove the latest update and fix the inaccessible boot device.
    27) If this does not fix the inaccessible boot device plan a registry repair.

    Report into the thread your progress with images of the above steps.
