Use Bootrec.exe in the Windows RE to troubleshoot startup issues or BSOD. This Error is attempting to read the boot configuration data.

bootrec /fixmbr

bootrec /fixboot

To do this, type the following commands at the Windows RE command prompt:

    So after you install windows 10 on a flash drive, you just plug it into the problem pc? But then which option do you select from F1-9 ?

  2. Do we need to insert the USB to the computer which we want to repair??
    And if we need do this what after inserting that USB??

    Actually NOTHING worked from this video, there was error about acces denied and not finding right path for C: and other type of stuff. But I simply just tried to install new windows and windows said that i have to set username and password and I tried to name it like my old account, but windows said i can't so that is when i knew something is wrong… Then i just added 1 to my previous name and i logged to windows on brand new account and then just logged on old account and it works ! I had to download some drivers and etc. and now in fact I with my own hands resolved this error πŸ™‚
