[Solved] Dual boot Arch Linux with Windows 10

In my Acer laptop I have Windows 10 installed on /dev/sda4 and the ESP partition is /dev/sda2.

As described in the Beginner's Guide I installed Arch Linux on a newly created partition /dev/sda5 and swap /dev/sda6 with the Windows 10 created ESP  /dev/sda2 as /boot.
As the bootloader I chose systemd-boot which is recommended by the guide if the motherboard is UEFI (which is)

I configured the /boot/loader/loader.conf as follows;

timeout 10
default arch

Created an entry for arch.conf at /boot/loader/entries/arch.conf as follows;

title          Arch Linux
linux          /vmlinuz-linux
initrd         /initramfs-linux.img
options        root=/dev/sda5 rw

But after rebooting Windows 10 boots by default. Couldn't even see the bootloader menu. Also no option to select Linux Boot Loader in boot options. What am I doing wrong?

Note: Both fastboot(Windows 10) and secureboot (UEFI) are off.

Re: [Solved] Dual boot Arch Linux with Windows 10

The firmware is probably loading the Windows bootmanager automatically.

Check the boot order with

#efibootmgr -v

Change the boot order with:

# efibootmgr -o xxxx,yyyy,zzzz

If the "Linux Boot Manager" (or so) is already first in the list, change the boot order from Windows as per https://wiki.archlinux.org/index.php/Un … boot_order

The command would be:

bcdedit /set {bootmgr} path \EFI\systemd\systemd-bootx64.efi

EDIT:

@yoshiserry: re-install systemd-boot, see https://wiki.archlinux.org/index.php/Sy … t#EFI_boot

Re: [Solved] Dual boot Arch Linux with Windows 10

I have seen weird UEFI implementations. On a Packard Bell laptop (I think they are the same as ACER) the UEFI automatically detect the Windows boot manager and put it first. To boot something other by default, you have to go in the firmware setting and select the hard disk as default boot device instead of Windows. As I understand booting from the hard disk really mean "respect the normal UEFI boot variables". I have found a lot of problems on the internet with UEFI's "that love Windows". One other trick is to rename the Windows boot manager as well as bootx64.efi (a copy of the Windows boot manager). You can still load Windows by launching the renamed file with your boot loader (Windows shouldn't be affected).

Re: [Solved] Dual boot Arch Linux with Windows 10

OK, I have tried the suggestion of @Head_on_a_Stick.

#efibootmgr -v

Returns all my boot options. It has Linux boot manager in the list but boot order didn't specify any thing about it.

So, I manually edited the boot order by

# efibootmgr -o 1003,1001,2001 and something.

But, the problem is same. Boot order is reverted back after an reboot.

So I tried the other suggestion.

bcdedit /enum firmware

Contains my Linux boot manager. So I ran

bcdedit /set {bootmgr} path \EFI\systemd\systemd-bootx64.efi

Thanks @Head_on_a_Stick this did solve my problem. Now I have a working dual boot of Windows 10 and Arch Linux

Re: [Solved] Dual boot Arch Linux with Windows 10

Thanks
following this topic I've solved the same issue
the grub is put in last place and using efibootmgr the order is not changed at reboot
instead with bcdedit from windows all is ok

bye
