    Mere - 

     

    Try mounting read/write ("sudo mount -o rw,remount /") and then editing /boot/efi/boot/grub.cfg

    That's just a guess though

    I tried "sudo qemacs /boot/efi/boot/grub.cfg" but got almost an empty file with no timeout to edit

    the following command :

    ls -a /boot/syslinux 

    shows 6 files in the syslinux folder, which is already bad luck if you believe in the devil lol

    1) README 2) default.cfg 3) root.A.cfg 4) rootB.cfg 5) syslinux.cfg 6) usb.A.cfg

    when I read, the README file, I'm told : 

    Partition 12 contains the active bootloader configuration when booting from a non-Chrome  OS BIOS

    so that must mean grub is on partition 12, i have 

     

    no idea how to mount that in Chromium OS / CloudReady

    it seems it's also not like Ubuntu's Grub, because thats under "/etc/default/grub" no such thing under /etc/default on here, only useradd vboot_reference, which both are to do with something else, best bet is partition 12

    end of the road, someone else with more skill will need to take over

    For us it's actually partition 27 because of the room we leave for Windows dualboot.

    You'd need to run

    Sudo mount /dev/sda27 /tmp/directory-you-created

    Then you find editing the files would work.

    When I follow your steps OP

     

    I end up with an error :

    mount: mount point /tmp/sda27 does not exist

     

    What I entered :

    sudo mount /dev/sda27 /tmp/sda27

    I have found a work around, I entered :

    sudo mount /dev/sda27 /tmp/

    I then went to : /tmp/efi/boot 

    & found 3 files, bootia32.efi bootx64.efi grub.efi

    I then did the following command :

    sudo qemacs /tmp/efi/boot/grub.efi

     

    I edited the timeout from 0 to 3, when i rebooted, the time out was still 15, then grub booted the other grub which was the one i edited, wrong one, so in effect i increased the boot time to 3 seconds more, i cant find what i need to edit

    Any update on this? Would absolutely LOVE if I could make the delay like 1/2 seconds. 99% of the time I just want it to boot into ChromeOS. In the off-chance I want to jump into Windows, I can easily click the down arrow to pause the timeout within 1-2 seconds.

    Thanks! (:
