   hi,
   I am using

   $ uname -a
   Linux lxuser-Latitude-3580 4.10.0-28-generic #32~16.04.2-Ubuntu SMP Thu Jul 20 10:19:48 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
   $ lsb_release -a
   No LSB modules are available.
   Distributor ID: Ubuntu
   Description: Ubuntu 16.04.3 LTS
   Release: 16.04
   Codename: xenial
   $ grub-install --version
   grub-install (GRUB) 2.02~beta2-36ubuntu3.12

   I want to run slitaz fully from RAM by using its iso file and adding entry in grub2 menu .
   Has anybody done that ?
   If yes , can you provide details like custom_cfg_file and link to iso file.
   Thanks.

   BTW , I have tried http://mirror.slitaz.org/iso/stable/flavors/slitaz-4.0-core.iso but I get kernel too old. and in case of rolling version it hangs up.

   Hi,

   A simple entry for the 4-in1 Rolling ISO:

   menuentry "LiveISO" {
      loopback taziso (hd0,1)/boot/slitaz-rolling.iso
      linux (taziso)/boot/bzImage ro root=/dev/null kmap=fr-latin1 autologin
      initrd (taziso)/boot/rootfs4.gz (taziso)/boot/rootfs3.gz (taziso)/boot/rootfs2.gz (taziso)/boot/rootfs1.gz
   }
   

   Of course you can use the name you want instead "taziso"; and adapt (hd0,1) according at where is the ISO.
   BTW, take care of the support where your ISO is stored. I meat some troubles with NTFS.

   @Ceel
   I did as you have mentioned .
   I get a plain purple screen when I select the option 'LiveISO'
   I am sure that my iso is in right partition (type ext4) and folder but cannot say what is going on as there are no prints on screen.
   Is there a way to find out the cause of hangup ?

   Thanks.

   Maybe the kernel does not recognize your graphic card. Try to boot in console only:
   At the GRUB menu, select LiveISO but don't press [Enter], press [E]. Then edit the initrd line; supress (taziso)/boot/rootfs3.gz (taziso)/boot/rootfs2.gz (taziso)/boot/rootfs1.gz and press [F10] to boot.
   If it's OK, then boot X only: same as above but supress (taziso)/boot/rootfs2.gz (taziso)/boot/rootfs1.gz.
   By the way, in your grub.cfg it would be better to suppress autologin (and of course if you don't use a french keyboard kmap=fr-latin1 :/ )

   Hi, I don't know if it still works, but in that case it would boot from the grub with a "screen=text" (without quotes) then once logged in as root in text mode, it would give a "tazx" that would allow "install or reconfigure Xorg". Obviously only if you have internet available in the lan socket...
   At the end to test the graphics was enough to give a "slim" or simply "startx"

   As suggested by gibor, you can run tazx as root and install or reconfigure Xorg; then select the intel driver
   or from the prompt as root:
   tazpkg -gi xorg-xf86-video-intel
   Then startx. If it fails again, post the new Xorg.0.log.

    ok
    I will try that .

    I also have another laptop . Its model is https://pcsupport.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-edge-laptops/thinkpad-e470/20h1
    On it , I find that I get hungup purple screen after selecting option in grub2 even when rootfs4.gz is only present . Should I start a new thread for that one ?

    As root , I ran tazx and tried xorg , xorg-light , slim one by one but still no gui.
    Then I ran tazpkg -gi xorg-xf86-video-intel but it says already installed.
    Here is new failure log on trying startx .

    I found a topic on the Linux Mint forum about the Intel HD Graphics 620 (your graphic card); seems it needs at least a kernel 4.4 or later to work... :(

    Concerning the Lenovo, after you selected LiveISO, you even don't see something like this
    [Linux-bzImage, setup=0x3e00, size=0x3b3310]
[Linux-initrd @0xf5dc000, 0x903708 bytes]
    before to get a purple screen?

    I guess the last hope is to add "nomodeset" to the grub...
