I installed Manjaro alongside Windows 10 but system directly boots to W10 if I ever boot into W10.
To solve it, I followed this advice: GRUB not showing up on UEFI pc
sudo grub-install sudo cp /boot/grub/x86_64-efi/core.efi /boot/efi/EFI/boot/bootx64.efi sudo efibootmgr -c -d /dev/sda -p 1 -L "manjaro" -l "\EFI\Manjaro\grubx64.efi" sudo update-grub
After restart everything is all right. Grub shows up and I can select to boot to Manjaro. Then shut down and then boot with Grub again any time.
BUT if once I select to boot W10 it boots and never shows Grub again! My efibootmgr does not list Manjaro again!
The only way to boot Manjaro again is by booting from live USB -> Detect EFI bootloaders -> select Manjaro.
At next step GRUB 2.04 shows up and OSes can be selected. Boots to any OS I select.
The hardware is a SONY VAIO notebook with nVidia GPU.
Please help me to solve the boot issues. Thanks in advance!
EDIT: Both Win10 and Manjaro are installed in UEFI mode.
