menuentry 'Kubuntu'  {
search --no-floppy --set=root --label "main"
linux /@/boot/vmlinuz root=LABEL=main ro rootflags=subvol=@
initrd /@/boot/initrd.img
}

Note that:

• The rootflags=subvol phrase is specific for booting from a btrfs.

I use EXT4 filesystem. The above didn't work. I question what label your referring to. Here's a snippet of my grab.cfg:
This works

menuentry 'xubuntu' --class ubuntu --class gnu-linux --class gnu --class os{
insmod all_video
	insmod gzio
	insmod ext2
	search --no-floppy --fs-uuid --set=root ae1bb60b-0428-47ed-bc28-2f64bb54fe9f
	linux /boot/vmlinuz root=UUID=ae1bb60b-0428-47ed-bc28-2f64bb54fe9f ro quiet splash pci=noaer
	initrd /boot/initrd.img
}

This fails. Doesn't understand the "@"

menuentry 'xubuntu'  {
search --no-floppy --set=root --label "xubuntu"
linux /@/boot/vmlinuz root=LABEL=xubuntu ro
initrd /@/boot/initrd.img
}

The label I used, I got from lsblk:

EDIT: It boots now if I get rid of that "@" stuff. Whatever that is.

the "@" stuff is specific to the BTRFS file system , you are on EXT4 , so irreverent to you and shold not be in your "grub.cfg"

Thanks Vinny. I thought that might be the case. I'm starting the really like labels instead of uuid's. Not sure why it took me so long. "old dog, new tricks"
