Hello Pludi,

Thanks for you answer. After many tries, I got the messages that states that the kernel is already installed, as well as the kernel image.

So far, I saw that /boot/vmlinuz and /boot/initrd are ok.

After another searches I found that the real problem is that GRUB (2) is vanished the config files, at least the LM10 records.
It has only the /memtest options and /windows boot record.

Trying again to many forums, I did not managed even with Super Grub Disk to deal, because, it seems that on the LM10 installin, I choosen (poorly) to have a ext2 fs, than ext4.
Trying another steps, I found on the SourceForge the bootscript for debugging such situations, and here are the output.

I hope to be clear for the experts to see what is my issue and the solution: in fact, I have no records in Grub/2 menu to point to /dev/sda7 LM10 installation.

Please pay some attention and give me some advice for this.

Thanks all for help.

Boot script attached. Inserting inline, on this reply, is loosing the formatting.

extlinux(1)						      General Commands Manual						       extlinux(1)

NAME

       extlinux - install the SYSLINUX bootloader on a ext2/ext3 filesystem

SYNOPSIS

       extlinux [options] directory

DESCRIPTION

       EXTLINUX is a new syslinux derivative, which boots from a Linux ext2/ext3 filesystem.  It works the same way as SYSLINUX, with a few slight
       modifications.  It is intended to simplify first-time installation of Linux, and for creation of  rescue  and  other  special-purpose  boot
       disks.

       The  installer is designed to be run on a mounted directory.  For example, if you have an ext2 or ext3 usb key mounted on /mnt, you can run
       the following command:

	      extlinux --install /mnt

OPTIONS

       -H, --heads=#
	      Force the number of heads.

       -i, --install
	      Install over the current bootsector.

       -O, --clear-once
	      Clear the boot-once command.

       -o, --once=command
	      Execute a command once upon boot.

       -r, --raid
	      Fall back to the next device on boot failure.

       --reset-adv
	      Reset auxiliary data.

       -S, --sectors=#
	      Force the number of sectors per track.

       -U, --update
	      Updates a previous EXTLINUX installation.

       -z, --zip
	      Force zipdrive geometry (-H 64 -S 32).

BUGS

       I would appreciate hearing of any problems you have with SYSLINUX.  I would also like to hear from you if you have successfully	used  SYS-
       LINUX, especially if you are using it for a distribution.

       If  you	are reporting problems, please include all possible information about your system and your BIOS; the vast majority of all problems
       reported turn out to be BIOS or hardware bugs, and I need as much information as possible in order to diagnose the problems.

       There is a mailing list for discussion among SYSLINUX users and for announcements of new and test versions. To  join,  send  a  message	to
       majordomo@linux.kernel.org with the line:
