[SOLVED] Stuck trying dual boot with W10

Hi.
At first I installed Arch, then W10
/sda1 -> arch ext4
/sda2 -> swap
/sda3 -> boot partition arch
/sda4 -> W10
/sda5 EFI boot

i mounted /sda1 on /mnt,  /sda3 on /mnt/boot and /sda5 on /mnt/boot/efi

by installing grub and efibootmgr with "arch-chroot" command on arch cd, i could make a folder named Grub which contains a file .efi. I tried to copy it to Boot folder, or /Microsoft/Boot folder, overwriting original file with no results.

What am I doing wrong?
Thanks

Re: [SOLVED] Stuck trying dual boot with W10

Why do you have separate "boot" and "efiboot" partitions?

Also, what exactly is the problem? You're telling us what you have done, but not what is happening.

Note: If you are going to dual boot (yuck), it is recommended to install Windows first, then Linux.

Are you following the Beginners or Installation guides? I think not...

There should be no need to manually create a "grub" folder or copy anything to the Microsoft folder - except in exceptional circumstances due to buggy EFI firmware.

As mrunion says - install Windows first then follow the Beginners Guide.

It would have been more useful to post the actual output of

lsblk

rather than the hand created tree you supplied which may not reflect your actual partitions and does not include some vital info (such as mountpoints etc)

Re: [SOLVED] Stuck trying dual boot with W10

sorry for not following the guide at first, i just did what I though, and look for bad information on google.
Now I started over again, following the begineers guide, I'm able to boot W10 perfectly, and have installed arch

/dev/sda1 arch
/dev/sda2 swap
/dev/sda5 EFI
/dev/sda4 W10

but now i continued to try to install grub, following the apropiate link to arch wiki.

got into arch-chroot with partition mounted on /boot, installed grub and efibootmgr with pacman.

grub-install --efi-directory=/boot/efi /dev/sda

grub-mkconfig .... etc etc

but when i restart it boots W10 as nothing happened. I'm writing now on windows, so i'll post lsblk when i restart again
[EDIT]

solved, --efi-directory route was incorrect, just had to write /boot.

Anyway, reading the guide was not enough, got that solution from another site
