Restore Uefi

Every time windows 10 installs a service pack, grub is removed as the default boot option.. In this page you can read how to resolve it.

Ubuntu

If Grub is managed by Ubuntu.

Open a CMD as admin and run:

bcdedit /set {bootmgr} path \EFI\ubuntu\grubx64.efi

This will replace the Windows boot entry in UEFI, with one that boots into GRUB. Assuming your GRUB menu then includes a working entry for Windows, you now have working dual-boot

Fedora

If Grub is managed by Fedora use the following:

bcdedit /set {bootmgr} path \EFI\fedora\shim.efi
