    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
    Code:
    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 "@"
    Code:
    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:
    Code:
    NAME        FSTYPE LABEL       UUID                                 MOUNTPOINT

    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"
