Hello.
I’ve installed pre-last tumbleweed stable release as a second system (with windows 10), hovewer something went wrong with grub or mbr, so instead of menu with list of available systems there is grub console appears on startup, it’s possible to boot into installed system using it or bootable usb.

I also a little bit confused with root returning (hd0, 6) as far as I have only efi partition on sda 4 and btrfs on sda5.
I’ve chosen legacy boot and right boot order in bios, tried reinstall grub2 and even os itself, that didn’t help. I guess i miss something.
