Dualboot with Windows 10 in another HDD

Hello there!

I'm installing ArchLinux in another HDD along Windows 10. My motherboard has SecureBoot disabled since the first day I bought. I was able to install Antergos with Windows 10 without any problem.

I created the partitions with grub:

[1TB HDD partitions, EFI]
	/sdd1	-	EFI		(ef00, 600MiB)
	/sdd2	-	root	(8300, 430GiB)
	/sdd3	-	home	(8300, 496GiB)
	/sdd4	-	swap	(8200, 4.9GiB)

mkfs.vfat /dev/sdd1
mkfs.ext4 /dev/sdd2
mkfs.ext4 /dev/sdd3
mkswap /dev/sdd4
swapon /dev/sdd4
mount /dev/sdd2 /mnt
mkdir /mnt/boot
mkdir /mnt/home
mount /dev/sdd1 /mnt/boot
mount /dev/sdd3 /mnt/home
pacstrap /mnt base
genfstab -pU /mnt >> /mnt/etc/fstab
arch-chroot /mnt

Now, I cannot. I did the same as https://wiki.archlinux.org/index.php/GRUB#UEFI_systems. The problem is when I try to install grub:

pacman -S grub intel-ucode os-prober dosfstools efibootmgr efitools refind-efi
grub-install --efi-directory=/boot --bootloader-id=GRUB2 --boot-directory=/boot --target=x86_64-efi /dev/sdd
grub-mkconfig -o /boot/grub/grub.cfg

I appreciate the help.

grub-install --efi-directory=/boot --bootloader-id=GRUB2 --boot-directory=/boot --target=x86_64-efi /dev/sdd

Why are you trying to install GRUB to /dev/sdd? On EFI systems the bootloader must be installed in the ESP (read: the EFI partition), in your case /dev/sdd1.

https://wiki.archlinux.org/index.php/GR … allation_2
I don't know where do you read that command, but the right one (as the wiki states) is

# grub-install --target=x86_64-efi --efi-directory=esp_mount --bootloader-id=grub

where esp_mount is your EFI partition, [EDIT] better: the mount point of your EFI partition.

Installing a bootloader on a disk without specifing the partition is the case of a BIOS/MBR installation, which is not yours.

So, if I did:

mount /dev/sdd1 /mnt/boot

And then the chroot, my esp will be /boot?

Indeed.

However, the first steps for setting up Arch (actually, most of the things you'll need for a basic installation) are well documented in the wiki, start from the installation page and thoroughly go to post installation, be sure you don't miss them and welcome to the forums
