I followed the Wiki instructions to create a new SD card installation. Putting the card into the Pi (3B+), however, has no effect. The monitor says "No signal detected" and there is no activity indicated by the friendly LEDs.
What I did:
Formatted the card with ext4 using gparted.
Copied the image to the card using
dd if=LibreELEC-RPi2.arm-9.0.2.img of=/dev/sdb1 bs=4M
per the instructions.
Do I have to set the boot flag on the card in gparted?
When I do parted -l I see
Model: Generic STORAGE DEVICE (scsi)
Disk /dev/sdb: 15.6GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Number Start End Size Type File system Flags

Hmm. No filesystem? Well maybe that's why the Pi doesn't like it, then...
fdisk -l /dev/sdb1
Disk /dev/sdb1: 14.5 GiB, 15548284928 bytes, 30367744 sectors

So... there is a filesystem after all? Confused as... something...
