    Windows 10 not starting after installing Ubuntu 18.04


    Hi,

    I recently installed Ubuntu 18.04 on my Lenovo laptop, hoping to be able to access both Ubuntu and Windows according to my needs. During the Ubuntu installation I created a new partition on my HD and since then Windows entered on Automatic Repair mode. Ubuntu is currently working well and I do not want to uninstall it when trying to recover Windows, if possible.

    I have searched extensively for other threads in here, but all of them refer to Ubuntu being installed on a different drive. On this thread, Avocado explains several options for restoring windows boot (post #24). I have tried running bcdboot D:\windows but after that I get an error code 0xc000000d (screenshot below) when booting Windows.

    Would there be anyway to get Windows working again without having to uninstall any OS?

    From what I understood, I could delete and recreate the EFI system partition, but I imagine that would erase the Ubuntu system files as well, which I am trying to avoid.

    I am attaching below the screenshots of my disk volumes and partitions, in case this is helpful.

    For reference, I have a Lenovo that came with Windows 8, but I recently upgraded it to Windows 10 (which was working fine before I installed Ubuntu and created the new partition).

    Thank you very much!

    Installing Windows 10 alongside Ubuntu?

    Ubuntu comes as an ISO file, that has it's own "Installer" that automatically can adjust partitions for running two Operating Systems along each other. My suggestion is to go ahead and make a bootable drive (USB, CD, etc), or buy one. Try to install Windows
    10, and if you fail, you can use the bootable drive to re-install ubuntu along with Windows 10.
