```sh

# /mnt/efipart/EFI/BOOT/grub.cfg

set timeout=1

menuentry "Rancher from GPT" {

    search --no-floppy --set=root --label RANCHER_STATE

    linux    /boot/vmlinuz-4.14.138-rancher printk.devkmsg=on rancher.state.dev=LABEL=RANCHER_STATE rancher.state.wait panic=10 console=tty0 console=ttyS0 rancher.autologin=ttyS0

    initrd    /boot/initrd-v1.5.8

}

```

## Change kernel boot parameters

Because we're using UEFI, `ros config syslinux` won't work for editing kernel boot parameters. Use this instead:

```sh

$ sudo system-docker run --rm --privileged -it -v /:/host alpine /bin/sh

# inside the alpine container:

$ mkdir -p /mnt/boot; mount /host/dev/vda1 /mnt/boot

$ vi /mnt/boot/EFI/BOOT/grub.cfg

$ umount /host/dev/vda1

# exit the container and reboot rancheros

```
