    Can稚 reset MBR in command prompt


    I知 running windows 10 on macbook pro bootcamp and I知 trying to salvage my system without losing anything

    i知 getting BSOD but before, i used to try to reboot a few times and eventually i would be able to get in, not anymore all of a sudden. i知 trying to reset my mbr

    attrib c:\boot\bcd -h -r -s
    gives me
    c:\boot not found


    Bootrec /RebuildBcd
    gives me
    Total identified Windows installations: 1

    but then when i get to
    C:\Windows Add installation to boot list? Yes<Y>/No<N>/All<A>
    i choose yes which leads to
    the requested system device cannot be found

    i知 not experienced enough here to know what i知 doing so any help is useful

    Why are you trying to change the MBR?

    Many search results point to MBR resetting, but it only works for a small number of people as MBR issues is rarely the cause.

    Run startup repair, it probably will fail but it will create a file srttrails.txt which may provide more insight. Grab a USB device to plugin to your computer.

    Go to command prompt in the recovery environment, enter the following commands. After each command press enter
    Code:
    diskpart
    list volume
    Take note of the letter of the volume where the size matches the size of the USB.

    Next, enter the following commands, after each command press enter
    Code:
    exit
    copy "C:\Windows\system32\logfiles\srt\srttrails.txt" "X:\"
    Replace X with the letter of the USB that you just took note of. Now the srttrails.txt file should be on the USB, connect the USB to another device that you can use to upload srttrails.txt.
