18.04 – Windows 10 not booting after dual boot

I am not very familiar with Linux so please bear with me.

I have tried to dual boot my Windows 10 machine with Ubuntu 18.04. After succesfully installing Ubuntu using the “install alongside windows” option, I can no longer boot into Windows. In Grub there is still a windows boot manager option, however, when I select that option, it takes me to the windows recovery. There it shows me error code 0xc0000001. As an additional note, Ubuntu works fine and I can still see my windows files in the file explorer in Ubuntu.

I have tried the following thing without succces:

  • bootrec /fixmbr and bootrec /fixboot on windows installation media
  • boot-repair in Ubuntu
  • sudo update-grub

Any advice would be appreciated!
