dual boot with Linux

[infinityux--- via freebsd-questions]

Hi all I am trying to dual boot my freebsd system with opensuse Linux so I made some changes to appear FreeBSD in grub boot menu. In opensuse I wrote$ sudo -i# nano /etc/grub.d/40_custom     And then,     menuentry "FreeBSD" {set root=(hd0,gpt2)kfreebsd /boot/loader }Now though freebsd is appearing in boot menu but when I am selecting one of them an error message is saying error:invalid signaturePress any key to continue... Can anyone help me? Do I have to install Linux as my first OS and then FreeBSD to appear it in grub menu?

error:invalid signaturePress

If I understand
http://askubuntu.com/questions/654530/error-invalid-signature-when-configuring-dual-boot-ubuntu-14-04-and-windows-1
correctly, than it might be, that one install is installed for
UEFI/secure boot and the other isn't. A shot in the dark, maybe a
default Suse nowadays assumes UEFI/secure boot while your FreeBSD
doesn't.

If I would have a mobo with UEFI/secure boot, I would take a look if
it's possible to turn of secure boot or to switch to a classic BIOS.

I can't help with this, since I don't own a UEFI/secure boot mobo.
AFAIK it gains you nothing and only is the source for issues.

recently I have installed OpenSUSE beside FreeBSD.

Does it mean that you first installed FreeBSD. It was possible to boot
FreeBSD. Then you installed Suse and after that booting FreeBSD was
impossible?
