I just set up Manjaro on my machine, but I’m facing a peculiar problem: Grub only starts correctly when I manually boot it via BIOS, otherwise it jumps straight into Grub Rescue with an error about no device and an unknown filesystem.

No, there is only one drive connected to the system.

Despite all other devices being turned off, the system still doesn't start properly.

I think you have multiple grub setups; some might use UEFI and one could reside in the MBR. The default boot is distinct from the one forced via BIOS, and the failed attempt suggests a missing grub config file on an unreachable device. In fact, this seems to be the only explanation possible. Once you switch to Linux, check if 'ls /sys/firmware/efi/efivars' shows any entries. Use 'efibootmgr' to list boot entries and identify whether the BIOS force is legacy or UEFI. Which firmware modules are present? Updated May 21, 2019 by Wild Penquin
