I want to have Dual Boot, the problem is that if I install Arch Linux after Ubuntu I don't know how to make that Arch Linux detect Ubuntu.
I partitioned Ubuntu in this way
In Arch I only create root partition, so the result is this
Then I did this:
mkfs.ext4 /dev/sda4 mount /dev/sda4 /mnt mkdir /mnt/boot mkdir /mnt/boot/EFI mount /dev/sda1 /mnt/boot/EFI
The result is
Close to finish the installation I did
pacman -S grub efibootmgr grub-install --target=x86_64-efi --efi-directory=/boot/EFI --bootloader-id=GRUB grub-mkconfig -o /boot/grub/grub.cfg
But don't Found Ubuntu
Obs: I try making one EFI partition for Ubuntu and other EFI partition for Arch, I did the same process and nothing.
So what I need to do to add Ubuntu to Arch Linux grub. Thx
