Grub problem with windows 10, boot-repair and manual reinstall not working

So I've been having problems with my grub now and at this point I've read all the previous posts I could find.

after installing ubuntu 18 my grub can't find Windows 10, this is usually resolved by a simple update grub. but this time this did not help at all. next I tried installing grub-customizer which did not help. then I installed boot-repair and ran into this problem. it asks me to run a command to uninstall the grub but the output on terminal would print




no matches found: grub*-common




and I could not go to the next level on boot-repair. I tried manually reinstalling the grub by running sudo grub-install /dev/sda --root-directory=/mnt
but I got




grub-install: error: cannot find EFI directory.




can anyone point me to a direction on how can I fix my grub?

thanks in advance and any help appreciated.

  • @oldfred I tried doing boot repair according to the link you provided. there is still no difference. and the repair never finishes so there is no repair.

  • Do not run repair, just run report, or are you not able to run report? Are you connected to Internet?

  • @oldfred I can't seem to only run report. I should mention that I'm running this from a working install (I can access my linux, I can't access my windows). should I try this with a live usb?
