    No boot: Unaccessible boot device


    HP Notebook 2 years old, came with W-10
    When booted, get a BSOD with "Unaccessible Boot Device".Able to enter the HP Diagnostics and the HDD tests OK.
    I also booted from Linux Mint and was able to access the drive and copy all the data off to a USB drive.
    Had customers with Black screen boot after this llast update but this on is different.
    Any help?
    Pete

    Hi Navy,
    I'll try that. I use Hiren's Boot: Hiren Discussion Platform which has almost the same setup but I'm going to try Kyhi's and see if its easier to use.
    Will get back.

    After you return to windows please perform the following steps:
    1) run this log collector and post a zip into this thread
    2) open administrative command prompt and type or copy and paste:
    chkdsk /x /f /r

    C:\Windows\system32>chkdsk /x /f /r
    The type of the file system is NTFS.
    Cannot lock current drive.

    Chkdsk cannot run because the volume is in use by another
    process. Would you like to schedule this volume to be
    checked the next time the system restarts? (Y/N)
    Type: y
    reboot
    This may take many hours so plan to run overnight

    3) Use the information in this link to find the chkdsk report in te event viewer. Copy and paste > notepad > save to desktop > post a share link into the thread using one drive or drop box share link
    Read Chkdsk Log in Event Viewer in Windows 10 Performance Maintenance Tutorials

    4) Run HD Tune: HD Tune website
    Please run these 3 tests and post images of each into the thread using one drive or drop box share links:
    a) Health (SMART)
    b) Benchmark
    c) Full error scan

    Kyhi's boot is the best I've seen.
    Macrium Reflect, boot repair, however did not fix.
    I'm running chkdsk although the HP System Hard Drive analysis found no problem.

    Reset would be an option if all else fails.
    I've had a number of black screen boots recently that I've had to use factory settings. PC still doing chkdsk /f

    Had to do a factory reinstall, the "Reset" feature was unavailable.
    Don't know what happened but at least, it's running and updating.
    One positive out of this is finding out about Kyhi's bootable tool.
    Beats my Hiren's and Spotmau.
    Thanks to everyone for jumping in.
