i tried boot repair and this is what i get http://paste.ubuntu.com/p/pGvXFt2gkx/

after trying booting into windows, windows recovery starts, in cmd i renamed volumes c to volume with windows installed on and i executed bcdBoot C:/Windows. After that i could boot into windows, but after that grub loader didnt show up and i executed bcdedit /set {bootmgr} path \EFI\ubuntu\grubx64.efi. After that i couldn´t again boot in Windows, becasue windows recovery starts and it seems so that i´am again in place where i started.

i have windows 10 and ubuntu installed on Samsung SSD 970 EVO 250GB


Did you disable secure boot? When I was installing ubuntu alongside windows I followed this tutorial. This article also explains how to disable secure boot.

  • i did disable secure boot, look to my edited post. – Zzzz Dec 11 '19 at 22:49

I often recommend that you install grub to the partition and not the drive. This allows Windows Boot manager to continue existing on it's own without issues. This will solve your Boot Repair problems.

Once Grub is installed to another partition, go to your EFI settings in the BIOS and add an entry for the new EFI file for grub.

I made a blog post about this on my site a couple of years ago, have a look:
