    You need to be connected to the internet and setup your Symbol File Path in windbg:
    Mine is set to:
    Code:
    SRV*D:\Symbols*https://msdl.microsoft.com/download/symbols
    so downloaded symbols are stored in D:\Symbols the first time they are downloaded, but you need the connection to the symbol server.

    Ive reinstalled windbg, set it up as per the instructions but its still giving me:

    Unable to open image file: C:\Symbols\ntoskrnl.exe\521EA0355e5000\ntoskrnl.exe
    The system cannot find the path specified.

    many times, then when its finished it says:

    *** doesn't have full symbol information. Unqualified symbol ***

    Zip up the dump you are working with and upload here so I can try it.

    Actually, why don't you run the Beta log collector and upload the zip file it produces. That may yield some additional info to help. Is the dump you are trying to look at in C:\Windows\Minidump? If so it will be included in the dump. If not zip and upload it separ4ately.

    Its about 400mb and its not mine so I wouldn't feel comfortable uploading it. It was on an SD card, I booted into a different partition (win 7) and checked eventvwr which reported one of the drives had NTFS issues and needed to be scanned. I'd had this error in win 10 on all drives before I flashed the BIOS. With it still reporting the issue I've decided to bin the motherboard and start again. I would like to getiwindbg running properly though for future problem solving.

    Try running WinDBG as Administrator to set the Symbol path. ZTruker has his set to create the Symbols folder to D:/Symbols.

    Windbg can be run with a database on the computer or using the live Microsoft database.
    The later method is slower but more up to date.

    See if you can download and install Windbg 1.0.1812.12001

    I've been having a problem looking at any dump so I reloaded the most recent developer kit. Followed the instructions carefully but still I'm not getting the full expected output listed in Golden tutorial when you run the test dump.

    The box with the initial bugcheck is missing.

    When I run against a dump in forum I get this


    ************* Symbol Loading Error Summary **************

    ntoskrnl The system cannot find the file specified

    You can troubleshoot most symbol related issues by turning on symbol loading diagnostics (!sym noisy) and repeating the command that caused symbols to be loaded.
    You should also verify that your symbol search path (.sympath) is correct.
    For analysis of this file, run !analyze -v





    This is what I was getting before the reload. I checked tutorial again but I can't see the trees for the forest.

    Thanks

    Open another dump and results were better but still did not get what I will call the quick analysis box. Copied from tutorial so people will understand what I'm referencing.

    There are two main options for symbols:
    a) store on the computer
    b) use the live Microsoft database

    Windbg preview is not in the tutorial.

    See if you can download and install: Windbg preview

    If the dump came from a zip file, look at it in the zip file, don't extract it first. For some strange reason, this works.

    Double click on the zip file or right click on it, slide down to 7-zip then select Open archive.
    Navigate like you would if in File Explorer, to Crash Dumps folder.
    Double click on any dump. it should launch in windbg like it normally does, only symbol resolution works.

    If you have a dump and symbol files won't resolve, zip it then look at the dump in the zip file, Works correctly now and symbol file resolution works as it should.
