hi

just tried to install next on a laptop
so two things :
with the web interface, the install (the first button) never goes ahead, it's like a refresh.
with the command line, it failed to install properly; with the grub installation asked, it just doesnt success to create a new grub one.

i did it selecting ext4 as / filesystem.
but here, an hour i'm trying to install next on the laptop, it just doesnt want to.

on next of 30th, slitaz web installer first button just refresh the page.

on next of 15th, slitaz web installer doesnt launch at all.

so here i have a laptop who cannot just boot, cause grub have been killed by next installation attempt.

so i'm in a deep sh..

Maybe all your problems are just because no Grub is installed...
In this case
tazpkg -gi <your_favorite_grub>
is probably the solution :)

mount /dev/sda9 /media/flash
(where sda9 is my NEXT / install)
grub-install --root-directory=/media/flash /dev/sda9
and
grub-install --root-directory=/media/flash /dev/sda

give the same :
root@slitaz:/home/tux# grub-install --root-directory=/media/flash /dev/sda
cmp: EOF on /tmp/grub-install.img.7j727o

The file /media/flash/boot/grub/stage1 not read correctly.

next killed grub

I don't think so.

Configuration #1: Next installed on a USB media ext4 formated.
1. Installation of the boot loader from Next:
  
  Grub2
  # grub-install /dev/sdb
  or
  # grub-install --root-directory=/mnt /dev/sdb Installing for i386-pc platform. grub-install: warning: your embedding area is unusually small. core.img won't fit in it.. grub-install: error: embedding is not possible, but this is required for cross-disk install.
  I've repeated this step on a device with Extlinux already installed. After grub-install failed, nothing has been written on the device and it still found Extlinux
  
  Grub 0.97
  # grub-install --root-directory=/mnt /dev/sdb Probing devices to guess BIOS drives. This may take a long time. The file /mnt/boot/grub/stage1 not read correctly.
  
  Grub4dos
  # grub-install --root-directory=/mnt /dev/sdb Probing devices to guess BIOS drives. This may take a long time. cmp: EOF on /tmp/grub-install.img.RyvLNJ cmp: EOF on /tmp/grub-install.img.RyvLNJ cmp: EOF on /tmp/grub-install.img.RyvLNJ cmp: EOF on /tmp/grub-install.img.RyvLNJ cmp: EOF on /tmp/grub-install.img.RyvLNJ The file /mnt/boot/grub/stage1 not read correctly.
  
  Extlinux
  # extlinux --install /mnt/boot/extlinux /mnt/boot/extlinux is device /dev/sdb1

2. Installation of the boot loader from Rolling:
  
  Grub2
  # grub-install /dev/sdb Installing for i386-pc platform. /proc/devices: No entry for device-mapper found /proc/devices: No entry for device-mapper found /proc/devices: No entry for device-mapper found grub-install: warning: your embedding area is unusually small. core.img won't fit in it.. grub-install: error: embedding is not possible, but this is required for cross-disk install.
  
  Grub 0.97

  Grub4dos

  Extlinux

Configuration #2: Next installed on a USB media ext3 formated.
1. Installation of the boot loader from Next:
  
  Grub2
  # grub-install /dev/sdb Installing for i386-pc platform. grub-install: warning: your embedding area is unusually small. core.img won't fit in it.. grub-install: error: embedding is not possible, but this is required for cross-disk install.
  
  Grub 0.97,Grub4dos and Extlinux
  Work.
The problem is neither Next/Rolling nor the boot loader; it is linked to EXT4. Maybe it is possible that something is missing in the SLiTaz's packages?

Concerning Grub2, the problem can be different:
warning: your embedding area is unusually small. core.img won't fit in it..
The first sector can be to small on some media; modifying the geometry at formatting can solve (see also https://wiki.gentoo.org/wiki/GRUB2/Troubleshooting#grub-install:_embedding_area_is_unusually_small). I didn't try it.

Another solution when EXT4 is required: create a small and specific EXT3 partition for the boot loader. I use a similar way: my boot loader is installed on my separate /home partition. I never meet boot loader problems. I can install and re-install; just have sometimes to adapt the configuration file.

Another wiki where the topic with embedding is mentioned, and similar solution with creating a small 1 MiB partition mentioned by Ceel. It's long, search keywords 'embedd', '1 MiB':
