Fix UEFI bootloader when Dual Booting with Windows, using Windows

[AgentS]

There are several tutorials for fixing UEFI booting problems, due to Windows overwrites, or OEM manufactures Linux-unfriendly hardware, where Manjaro GRUB doesn’t load first/default after installing Manjaro or Windows upgrades.
This is a simple solution for fixing this from within Windows, which maybe the easiest and fastest fix for this, when you have a Windows multi-boot with Linux/Manjaro.

The solution comes from It’s FOSS 5 and originally posted by @ManjaroBlack here :

1. Start/boot Windows
2. Run CMD as Administrator
3. Run this command (for a standard/default Manjaro UEFI installation, or adjust accordingly)

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

4. Reboot

That’s it! Grub should load first and WinOS can be started from its menu.

I edited it to read Windows instead of WinOS so people will find it searching for Windows. Hope you don't mind.
