[SOLVED] Kernel boot options removed by fault, no boot options

Hello Everyone,

First of all, I highly appreciate all Linux forum members and whole Linux community.

. I wish you the best for all of you !

I will try to be short and concise: I am using Linux Mint 10 for 2 months on 2 ws, and all went good so far (Vbox, developing, Unix scripting, etc); I am not a very beginner in UNIX, having some skills in PHP/MYSQL/APACHE/BASH/LINUX - WIN/BATCH as well (several years, let's say).

But what is happening now,

is putting me into a trouble: yesterday I have performed some wifi kernel modules installation with Synaptic and some new kernel were added to boot menu, some of them with --recovery option, some of them new ones. Uninstalling these last wifi modules (and probably another ones), all kernel modules (including the current (and good) one were uninstalled, of course, they disappeared from the boot menu as well).

I agree that was totally my fault because I have installed wifi modules which have required kernel recompiling, but I dd not know then the full image of this disaster.

In the last open session (just before reboot), I have seen that all kernel images/module disapperared from /root folder, /vmlinuz file disappeared too; of course using GUI boot loader, I have observed only 2 Memory test options and the M$Win OS (the second OS installed).

My issue now is: I would like to repair the previous Mint 10 installation, no to reinstall because it is taking some time to reparameter all settings .. if it is possible.

CURRENT STATUS:
> I have a Linux Mint 10 burned disk (this one where I typing these lines);
> wired/wireless network on;
> all partitions are not changed
> Linux Mint boot menu has only 2 Mem test option + 1 M$Win OS boot option
> Old Linux kernel definitions is missing from boot menu as well as from:
/root folder
in the / [root] there is no any vmlinuz binaries (I don't remember the correct name for the vmlinuz ..)
> I am able to burn any CD/DVD's, download any binaries/apps from the internet and so on.
> I am online now, ready to give you all details you need about my steps performed yesterday (as much as I remember ;(( -- poor of me ...)

QUESTIONS FOR YOU:
> I would like to avoid the full reinstallation in order to keep the old and full Linux Mint 10 destop;
> I would like to repair the linux kernel, putting it in the right place (/root, /) and create again the records in boot menu, in order to boot again LM10 as it was until yesterday evening.
> Hoping that this problem could have a solution, would you be kind to advise me a good procedure to peform (to install) as this kernel changes to do not happen again in the future.

Hoping that someone of you has encountered this before, I am here to follow your instructions. If the name of this topic could be redefined (in order to reflect this issue better), please do so or suggest me to do, I have not used so much the discussion forums until now, but I will do from now on

...

All the best for you.

Cristian

extlinux

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:
