operating system not found; booting from separate partition

Hey,
I tried to install Arch Linux on a laptop. I partitioned my hdd to have a boot partition and another partition which is encrypted with LUKE based on this tutorial . With lvm, I created a home, root and swap partition.They can all be mounted and I can chroot into the installed Arch Linux. I added lvm2 as well as encrypt to the HOOKS of /etc/mkinitcpio.conf so that I can properly access the HDD during the boot process. Into the default grub config, I included the line as shown in the linked tutorial above:

GRUB_CMDLINE_LINUX="cryptdevice=/dev/sda2:main root=/dev/mapper/main-root"

And I added the lvm module to preload in the grub config.

In the lvm config file, I set use_lvmetad = 0 .
I installed the GRUB bootloader on the whole disk (/dev/sdb) not just on a specific partition and generated the grub cfg file into the /boot folder, which is mounted by my small, unencrypted partition. I received no errors.

By rebooting, my BIOS doesn't find any operating system. My small bootpartition which is not encrypted has the bootflag set.
As suggested here , I checked where my bootable partition starts and it starts at sector 2048. I think that the bootloader somehow can't be called, but I'm no expert and my ideas start to come to an end.

UEFI or BIOS?
