[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.

wifi-radar(1) General Commands Manual wifi-radar(1) NAME
WiFi Radar - utility for managing WiFi profiles SYNOPSIS
wifi-radar [OPTION]... DESCRIPTION
WiFi Radar is a PyGTK2 utility for managing WiFi profiles. It will look for the config file in /etc/wifi-radar/wifi-radar.conf. You can change that in wifi-radar. If the configuration file does not exist, it will create it, so you must always run it within a correctly permitted account (as root or use sudo or pam). Recent versions partially implement WPA-TKIP with wpa_supplicant. You need a running wpa_supplicant installation with a /etc/wpa_suppli- cant/wpa_supplicant.conf file. Then by setting in your /etc/wifi-radar/wifi-radar.conf file the "use_wpa = yes" option and "wpa_driver = ipw" for example, wpa_supplicant will be launched when you connect using this profile. But currently you can't set your wpa_supplicant options like the psk, proto, key_mgmt etc. using wifi-radar. Your wpa_supplicant configu- ration file should be set and tested already. If you have different networks set in wpa_supplicant.conf, then you can switch using wifi- radar. The wifi-radar script accepts the following command-line options: OPTIONS
-v, --version for printing the version. FILES
/etc/wifi-radar/wifi-radar.conf See for more information. BUGS
Probably lots! Because of repeated scanning, WiFi Radar is very power consuming. Please report bugs to the mailing list <https://lists.anl.gov/mailman/listinfo/wifi-radar> MORE INFORMATION
