ok i've done it! it was not cool, but still. when i rebooted to login in windows 8 computer said that "there was no operating system found press ctrl + alt + delete to restart(something like that)" i made DELL Laptop diagnostic. HDD and DVD-ROM cozed problems... i was shocked. but i fixed it with Hyren boot i had it on my USB fortunately.

I've used commands that you gave me without problem but here's another problem now i cant see wireless even in network settings i can't find it anymore ... there is nothing about WiFi. i have screenshots but i can't upload it ... if you'll tell me how to i will ... (it's linux format thats why maybe)


I wrote that commands two times i lost log of the first but second time i saved so here it is:

Code:
------------------@ubuntu:~$ sudo su -l
[sudo] password for ------------------: 
root@ubuntu:~# find /sys/module/iwlwifi/parameters -type f -printf "%p %f\n"| while read ITEM SHORT; do echo "${SHORT}: $(cat $ITEM)"; done

root@ubuntu:~# grep iwlwifi -Hr /etc/modules.conf /etc/modprobe.d/ /etc/modules-load.d/

grep: /etc/modules-load.d/: No such file or directory
root@ubuntu:~# sudo rmmod iwlwifi; sudo modprobe iwlwifi 11n_disable=1

I'm sorry to hear you have had computer problems but none of the command I showed you could have directly caused any of that.

- If iwlwifi or one of the other modules you need to get your Wifi connection working isn't loaded then as a symptom of that /sys/module/iwlwifi might not be available. Ignore for now.
- Ignore /etc/modules.conf or /etc/modules-load.d/ doesn't exist too as we can see you've loaded options into /etc/modprobe.d/iwlwifi.conf. (And incorrectly: I explicitly told you two posts back to leave empty options like "debug=" out.)
- The "does not exist in /proc/modules" just means 'rmmod' didn't find the module loaded. Just ignore that too.
- The insertion error points to reading 'dmesg'. Did you and what did it say?

Also the fact the iwlwifi module doesn't load means we have to troubleshoot that first. IIGC kernel 3.2.0-29-generic was released somewhere last month. I don't like to speculate but if you had a bad or intermittent network connection and you have automatic updates on the system may have upgraded the kernel. Or did you upgrade the kernel manually? If so try booting a previous kernel version from your boot menu. In any case it would be good to proactively check your syslogs in /var/log for clues.

Locate the screen shot file and run t eh 'file' command on it ('man file' for details) and post what it returns.
